Abstract:
This article considers the presence of ‘self-reflexive narrative’ in field recording. The authors interrogate a common presumption within sonic arts practice and sound studies discourse that field recordings represent authentic, impartial and neutral documents. Historically, field recording practice has not clearly represented narratives of how, when, why and by whom a field recording is made. In contrast, the social sciences have already experienced a narrative ‘turn’ since the 1970s, which highlighted the importance of recognising the presence and role of the researcher in the field, and also in representations of fieldwork. This provides an alternative framework for understanding field recording, in considering the importance of the recordist and their relationship with their recordings. Many sonic arts practitioners have already acknowledged that the subjective, personal qualities of field recording should be embraced, highlighted and even orated in their work. The authors’ own collaborative projectThoughts in the Fieldfurther explores these ideas, by vocalising ‘self-reflexive narratives’ in real time, within field recordings. The authors’ collaborative composition,Getting Lost(2015), demonstrates the compositional potentials this approach offers.

Abstract:
Audio forensics is a method used to analyze sound or audio recordings. Voice or audio recording is one of the digital evidence that is easy to manipulate. One way to manipulate sound is to use magic call. Magic call has several levels of character voices that can be used such as cartoon, children, male and female voices. The analysis of the original voice recording with the magic voice recording is done by comparing the magic call sound and the voice with the original voice recording. The purpose of this study was to determine the voice recording produced by magic call from the magic call applications. As for the method used in this research is audio forensics, research on magic call sound using audio has never been done before. The results of this study indicate that the analysis of magic call sound recordings can be done using formant analysis and spectrograms, while pitch analysis on magic call voice recordings cannot be used. The formant and spectrogram values on magical voice recordings can still be searched because the original voice recordings have characteristics that are still attached to the magic recording calls.

Abstract:
Purpose Simultaneous recording of cervical (cVEMP) and ocular (oVEMP) vestibular evoked myogenic potentials aids in reducing the testing time when compared to conventional sequential recordings. The purpose of this study was to examine the test–retest reliability of sequential and simultaneous acquisitions of cVEMP and oVEMP. Method cVEMP and oVEMP were recorded in 35 normal-hearing individuals. The cVEMP and oVEMP were obtained using sequential and simultaneous methods. The VEMP recordings were performed across 3 sessions. The 1st 2 recording sessions were consecutive with a gap of 5 min between sessions. The 3rd recording session was after a gap of 3–5 days. Results Both simultaneous and sequential recordings showed fair-to-good test–retest reliability for latencies and amplitude of cVEMP and oVEMP. Conclusion Simultaneous cVEMP and oVEMP recordings can be used to obtain fast VEMP recording with test–retest reliability comparable with that of sequential recording.

Abstract:
Sound or audio engineering is a branch of the field of engineering, which involves the process of recording sound and reproducing it by various means, as well as storing in order to be reproduced later. Known as sound or audio engineers, these trained professionals work in a variety of sound production fields and expert in recording methods. They can be instrumental to implement the affordable technologies and technical process to distribute the audio data hence, making it accessible for future generations. The current role of these engineers not only to perform or limited to recording session but they create metadata for archiving and preservation for future needs. Currently, product sleeves of ethnographic recordings represent no technical elements of how traditional music recordings are produced. The product details focus only to some extent on historical elements and musical notation. To an audio archivist, declaring what devices are in a recording is not linked with preservation data. Apart from the format, the sleeved design, technical specification is essential to other social scientists such as audio engineer and field recordist of the future. The aim of the present research is to capture optimum dynamic range of the sound and applying a signal processing that would not alter the tonality, timbre and harmonic of the sound. Further applying a suitable information storage for the metadata to be preserve or archived for future accessing and reproduction.

Abstract:
Quantitative electroencephalogram enables mathematical analysis of neurological recordings while conventional electroencephalogram lacks the mathematical output; hence, its usage is limited to neurological experts. This study was to determine if quantified conventional electroencephalogram recordings were compatible and comparable with quantitative electroencephalogram recordings. A group of post-call doctors was recruited and subjected to an EEG recording using a conventional electroencephalogram followed by a quantitative electroencephalogram device. The patterns and quantified recording results were compared. A comparative analysis of the two recording sets did not find differences in the recording patterns and statistical analysis. The findings promoted the use of a readily available conventional electroencephalogram in quantitative brain wave studies and have cleared potential compatibility bias towards data merging.

Abstract:
This article explores recent theories of listening, perception and embodiment, including those by Mark Grimshaw and Tom Garner, Salomé Voegelin, and Eric Clarke, as well as consequences and possibilities arising from them in relation to field recording and soundscape art practice. These theories of listening propose auditory perception as an embodied process of engaging with and understanding lived environment. Such phenomenological listening is understood as a relational engagement with the world in motion, as movement and change, which grants access to the listener’s emerging presence, agency and place in the world. Such ideas on listening have developed concurrently with new approaches to making and presenting field recordings, with a focus on developing phonographic methods for capturing and presenting the recordist’s embodied auditory perspective. In the present study, ‘first-person’ field recording is defined as both method and culturally significant material whereby a single recordist carries, wears or remains present with a microphone, consciously and reflexively documenting their personal listening encounters. This article examines the practice of first-person field recording and considers its specific applications in a range of sound art and soundscape art examples, including work by Gabi Losoncy, Graham Lambkin, Christopher Delaurenti and Klaysstarr (the author). In the examination of these methods and works, first-person field recording is considered as a means of capturing the proximate auditory space of the recordist as a mediated ‘point of ear’, which may be embodied, inhabited, and listened through by a subsequent listener. The article concludes with a brief summary of the discussion before some closing thoughts on recording, listening and the field, on field recording as practice-research and on potential connections with other fields in which the production of virtual environments is a key focus.

Full text
Abstract:
By analyzing the biography of Ryszard Siwiec’s recording of his message, we explore the function and changing identity of sensitive sound recordings, and the ethics of handling them. In our view, sensitive recordings are linked to the experiences of trauma, exclusion, and injustice of those whose voices were recorded and the community they were part of. A recording may also be considered sensitive if it is used in a racist context or for other stigmatizing practices. Sensitive recordings are “difficult,” sometimes “troubling,” but also “moving”; they stir emotions. Although sensitive recordings are associated with physical and social death and exclusion, we view them and what is recorded on them as a form of life. Each recording has its own biography and agency, becomes an active actor in a complex social network, and is subject to the actions of other actors. Our analyses of the biography of Siwiec’s recording reveal its affective and emotional power, its role as a carrier of family and national memory, its changing identity, and its agency in shaping the identities of its listeners. We would like to argue that sensitive recordings require attentive and sensitive listening. This kind of listening becomes an ethical postulate that results from a concern for those whose voices are made public, the author of the recording, and the recording itself.

Abstract:
Voice recordings can be changed in various ways, either intentionally or unintentionally, one of which is by using a voice changer. Reference voice recordings and suspect voice recordings will be more difficult to analyze if suspect voice recordings are changed using a voice changer application under certain effects such as telephone effect. Voice Changer can be one form of activity that can be carried out by anti-forensics, making it difficult for investigators to investigate if the voice recording is changed with telephone effect. This study has two types of recordings, namely the reference voice recording (unknown sample) and suspect voice recording (known sample) that has been changed using a voice changer application with telephone effect. Investigations were carried out based on data results extraction and analysis using pitch, formant, and spectrogram using the Analysis of variance (ANOVA) method and the likelihood ratio method. The results of this study indicate that the application of voice changer can be one form of activity that can be carried out by anti-forensics so that it can be difficult for investigators to conduct investigations on sound recording evidence. This research may help forensic communities, especially investigators to conduct investigations on sound recording.

Abstract:
AbstractPurpose Some previous studies have suggested that invasive ictal recording may be omitted in patients with medically refractory temporal lobe epilepsy (TLE) that have localizing scalp ictal recordings despite having normal magnetic resonance imaging (MRI). We investigated if and how often invasive ictal recording provided additional information to their pre-surgical evaluations.Methods In a retrospective review of 302 patients with intractable TLE who underwent pre-surgical evaluation between 1991 and 2006, we identified 45 patients who had normal MRI. Localization by scalp ictal recording, invasive ictal recording, and surgical procedures were obtained from medical records. Primary outcome was measured by comparing the concordance of localization by scalp and invasive ictal recordings and surgery to determine if invasive ictal recording provided additional information.Results Twenty-five patients were included in the analysis. Invasive ictal recordings were concordant in 72.0% (18/25) of the patients with unilateral temporal onset found on scalp ictal recording. 28.0% (7/25) of patients had their surgical plan altered by the results of invasive ictal recording. 61.1% (11/18) of patients who received anterior temporal lobectomies (ATL) remained seizure-free. Of the patients who received different surgeries based on invasive ictal recording, 80.0% (4/5) remained seizure-free.Conclusions Our study showed that findings from invasive ictal recording changed the type of surgery in 28.0% of the patients. Invasive ictal recording may not be an absolute prerequisite for resective epilepsy surgery in some patients with intractable TLE with a supposedly normal MRI of the brain but may alter the surgical decision.

Abstract:
Audio recording is used in language and music education as an active learning resource to help students reflect on their performance and improve their accuracy. Recordings may be used to provide feedback on both verbal and nonverbal skills and to prepare professional candidates for talking to vulnerable users or other professionals. Despite its potential, recording among health, social, and education candidates to help them improve their digital relations skills is usually not part of pre-service training. Therefore, the objective was to assess the extent to which professional students were affected by recordings in live-stream settings and to explore their perspectives through qualitative elaboration. The design was a repeated cross-sectional mixed-methods study conducted in 2020–2021 (n = 1040 and n = 2238, response rate: 46% and 45%, respectively). Although participation was reduced, active online participation was low, regardless of recording practice. Educational background and age were determinants of active participation, regardless of the recording practice. Active students were the least affected by recording. Students wanted more recordings. Their perspectives revolved around different practices, privacy issues, and the recording used for traditional knowledge transfer instead of active learning. Although the General Data Protection Regulation must be met, we suggest that recording is an underused learning resource.

ObjectiveTo increase clinical application of vestibular-evoked myogenic potentials (VEMPs) by reducing the testing time by evaluating whether a simultaneous recording of ocular and cervical VEMPs can be achieved without a loss in diagnostic sensitivity and specificity.MethodsSimultaneous recording of ocular and cervical VEMPs on each side during monaural stimulation, bilateral simultaneous recording of ocular VEMPs and cervical VEMPs during binaural stimulation, and conventional sequential recording of ocular and cervical VEMPs on each side using air-conducted sound (500 Hz, 5-millisecond tone burst) were compared in 40 healthy participants (HPs) and 20 patients with acute vestibular neuritis.ResultsEither simultaneous recording during monaural and binaural stimulation effectively reduced the recording time by ≈55% of that for conventional sequential recordings in both the HP and patient groups. The simultaneous recording with monaural stimulation resulted in latencies and thresholds of both VEMPs and the amplitude of cervical VEMPs similar to those found during the conventional recordings but larger ocular VEMP amplitudes (156%) in both groups. In contrast, compared to the conventional recording, simultaneous recording of each VEMP during binaural stimulation showed reduced amplitudes (31%) and increased thresholds for cervical VEMPs in both groups.ConclusionsThe results of simultaneous recording of cervical and ocular VEMPs during monaural stimulation were comparable to those obtained from the conventional recording while reducing the time to record both VEMPs on each side.ClinicalTrials.gov identifierNCT03049683.

Abstract:
The recording industry is now over 120 years old. During the first half of its existence, however, few archives documented or collected its products. Many early recordings have been lost, and discography, the documentation of historical recordings, has mainly been in the hands of private collectors. An emphasis on genre-based discographies such as jazz or opera has often left other areas of record production in the shade. Recent years have seen a growth of national sound collections with online catalogues and at least partial online access to content. While academic historians have been slow to approach the field, there has been outstanding new research on the history of the recording industry, particularly in the USA and UK. This has encouraged the development of new academic research on musical performance, based on historical sound recordings. The article discusses some recent works in this field.

Abstract:
The paper compares the variants of the Shor heroic epic “Künnü körgen Kün Köök” (“Kün Köök that saw the Sun”) recorded in 1999 with an interval of two months in the narrator’s self-recording (written in January 1999) and in audio recording (recorded in March 1999 by L. Arbachakova from V. E. Tannagashev (1932–2007). The version in the audio recording was performed by the Kai narrator accompanied by komus in the performer’s apartment in Myski city. V. E. Tannagashev learned this epic from his teacher P. N. Amzorov. The small period between the recordings resulted in insignificant discrepancies in the versions that were complementary and hardly influenced the qualitative content of the legend. The Kai narrator’s memory did not let him down, with the plots almost coinciding and different epic formulas used only in some fragments of typical places, or there were some permutations or omissions of lines. Sometimes the narrator uses synonymous words, or there are repetitions and reservations. However, there are practically no such flaws in the self-recordings. The typical points used by the kaichi, sometimes expanded and colorful, sometimes compressed, probably depended on his mood, as well as on different ways of fixing the epic (in the kaichi’s selfrecording and audio recordings). Live performance is influenced by the mood, health of the narrator, and other factors. Self-recordings made by hand are the most time-consuming since they require physical effort, perseverance, attention. It is perhaps for this reason that the recording turned out to be more shortened.

AbstractThe development of recording is arguably the most significant change to have affected music in the twentieth century. Never before have people had access to so much music and in so many different ways and with so many different patterns of use. This paper examines some of the effects of recording on listening, starting with a brief outline of an ecological theory of listening and focusing on three specific characteristics of recordings: the interpenetration of music and the wider environment; recordings as medium and as object; and the relationship between social and solitary listening practices. Recording has attracted both utopian and dystopian commentaries on its effects on musical culture, and the paper concludes by considering both the opportunities and the drawbacks of recordings as a means of access to music.

This study aimed to describe the comparison between languages on Gatot Nurmantyo's Similar Voice Sample (SVS) recording with language on Gatot Nurmantyo's Original Voice Sample (OVS) recordings. The data source were one SVS record and three OVS records (OVS01—OVS03). Data were collected through observation, copying, and recording. The instrument for data collection was in the form of human, researcher himself with the recording devices and stationery. The analysis was carried out comprehensively with a review of various aspects including Phonology, Sociolinguistics, Discourse, and Stylistics. The results of the study were as follows. First, there were significant differences between languages on SVS and language on all three OVS recordings in terms of Sociolinguistic, Discourse and Stylistic aspects. Second, on the Phonological aspect there was a tendency for the similarities between language on the SVS recording and language on all three OVS recordings in several parts including the duration of word utterance, the energy intensity of the word utterance, and the sound of the words. Therefore, it could be concluded that on a Classical Likelihood Scales, the SVS and OVS recordings were not from the same speaker. Keywords: forensic linguistic, comprehensive, recording, Praat

Full text
Abstract:
Bat surveys are frequently undertaken using ultrasonic detectors to determine the species present in an area on the basis of the identity of echolocation calls. We compared three techniques for using the Anabat II detector: the detector pointed along tracks (flyways) versus the detector pointed across tracks (non-flyways); recording output to audio cassette (analogue) versus direct recording to computer (digital); and active hand-held recording versus static automatic recording. In addition, we derived a species-accumulation curve from all-night Anabat recordings in the wet–dry tropics of the Northern Territory. We found no significant difference between flyway and non-flyway recordings; significantly more calls were identified from digital recordings; and significantly more species were detected using hand-held than static recordings. Species-accumulation analysis suggests that the minimum time required to achieve a satisfactory (80%) inventory of bat species at a site is during the three-hour period immediately after sunset. We use our findings to make recommendations for the design of bat surveys using the Anabat II detector.

Their findings–that the mechanical limitations of recording possibly contributed to Edison's distaste for vocal vibrato–is mirrored in much of the work on early instrumental recordings, but whereas the effect for instrumental recordings was an increased vibrato, the solution for vocal recordings was the opposite.

Abstract:
Selected methods of quantitative analysis of video recordings are presented, which can be used to analyse images from both fixed cameras (highways, intersections, etc.) and vehicle-mounted cameras. The article deals with the use of video recordings in the reconstruction of road traffic accidents. Many drivers use digital video recorders (DVRs), the so-called dashboard cameras, which record the situation in front of or behind the car while driving. There are also many places where cameras are installed, such as highways, intersections, etc. In some situations, such recordings can be important evidence in establishing liability for a road traffic accident. However, in most of these cases, the video recording is only analysed qualitatively, while the article shows that a lot of quantitative information can also be obtained from the video recording, such as speeds, accelerations and directions of movement of the vehicles. Analysing the image of the camera moving with the vehicle is more difficult, but possible thanks to the analysis methods presented in the article. The reconstruction of a road traffic accident event using the presented methods can be carried out on the basis of recordings made with the help of recording devices that capture images of different quality. It is not necessary to know the parameters of the camera recording the image. However, knowing these parameters makes the analysis much easier. In addition, reference was made to the problems of image analysis that experts have to deal with when reconstructing accidents. It was pointed out that video recordings should be analysed using different methods depending on the situation they represent. The influence of the quality of the recording (resolution, distortion, image sharpness, recording speed, etc.) on the usefulness of the recording for obtaining quantitative information is also discussed. Finally, a method for estimating the uncertainty of the results is presented. The article confirms that it is possible to determine selected parameters of vehicle movement based on the analysis of the DVR recorder.

Abstract:
Background: Audio recording of cognitive behavioural therapy (CBT) sessions has been recommended but not yet widely adopted. It is believed to have positive effects on later recall and reflection by the patient and on supervisory quality and accuracy for therapists. Aims: To evaluate self-reported attitudes and behaviour regarding audio recording of therapy sessions in both patients and therapists in a setting where such recording is routinely carried out. Method: In a centre specializing in CBT for anxiety disorders, 72 patients completed a questionnaire at the start of therapy and 31 patients completed a questionnaire at the end of therapy. Fifteen therapists also completed a similar questionnaire. Results: Ninety percent of patients reported listening to recordings between therapy sessions to some extent. The majority reported discussing the recordings with their therapist. Patients typically planned to keep the recordings after therapy ended. Most patients and therapists endorsed positive attitudes towards the use of recordings. Similar advantages (e.g. improving memory for sessions) and disadvantages (e.g. practical issues and feeling self-conscious) of recordings were generated by patients and therapists. Therapists were more likely than patients to express concern about recordings being distressing for patients to listen to. Both patients and therapists regarded the use of recordings for therapist peer supervision purposes favourably. Conclusion: The use of audio recording of sessions as an adjunct to therapy (where patients listen to recordings between sessions) and for therapist supervision is rated as both highly acceptable and useful by both therapists and patients.

Abstract:
Various types of low-cost acoustic recording equipment are available to the scientific community and the general public. While financial budgets can restrict what equipment can be purchased for a particular application, it is necessary to quantify the limitations of particular systems to determine their usefulness. Direct comparisons between recordings using low-cost equipment and using high fidelity equipment can highlight how the quality of low-cost recording is affected, which can help to determine whether or not budget recording systems are sufficient for a particular application. The Cornell Lab of Ornithology developed a low-cost terrestrial recording device for bioacoustic data collection known as the SwiftOne. This device can be set with various sampling rates and configurable recording schedules, making them suitable for long term data collection. Multiple SwiftOne units were used alongside a high-fidelity data acquisition system in both laboratory and outdoor data collection, including loudspeaker measurements in an anechoic chamber, ambient recordings at a bird refuge, and at a coastal rocket launch. The overall quality of the low-budget data recordings is investigated to determine the usefulness of the SwiftOne in these acoustic environments. Analyses include comparisons of measured waveforms, spectral content, and sound pressure levels.

Abstract:
Purpose This study examined the utility of the Language ENvironment Analysis (LENA) recording system for investigating the language input to bilingual infants. Method Twenty-one French–English bilingual families with a 10-month-old infant participated in this study. Using the LENA recording system, each family contributed 3 full days of recordings within a 1-month period. A portion of these recordings (945 minutes) were manually transcribed, and the word counts from these transcriptions were compared against the LENA-generated adult word counts. Results Data analyses reveal that the LENA algorithms were reliable in counting words in both Canadian English and Canadian French, even when both languages are present in the same recording. While the LENA system tended to underestimate the amount of speech in the recordings, there was a strong correlation between the LENA-generated and human-transcribed adult word counts for each language. Importantly, this relationship holds when accounting for different-gendered and different-accented speech. Conclusions The LENA recording system is a reliable tool for estimating word counts, even for bilingual input. Special considerations and limitations for using the LENA recording system in a bilingual population are discussed. These results open up possibilities for investigating caregiver talk to bilingual infants in more detail.

Abstract:
Objective:To explore the influence of environmental conditions on pattern visual evoked potential (VEP) recordings.Methods:Fourteen subjects with no known ocular pathology were recruited for the study. In an attempt to optimize the recording conditions, VEP recordings were performed in both the seated and recumbent positions. Comparisons were made between recordings using either LCD or CRT displays and recordings obtained in silence or with quiet background music. Paired recordings (in which only one variable was changed) were analyzed for changes in P100 latency, RMS noise, and variability.Results:Baseline RMS noise demonstrated a significant decrease in the variability during the first 50msec accompanied by a 73% decrease in recording time for recumbent position when compared to the seated position (p<0.05). Visual evoked potentials recorded using LCD monitors demonstrated a significant increase in the P100 latency when compared to CRT recordings in the same subjects. The addition of background music did not affect the amount of RMS noise during the first 50msec of the recordings.Conclusion:This study demonstrates that the use of the recumbent position increases patient comfort and improves the signal to noise ratio. In contrast, the addition of background music to relax the patient did not improve the recording signal. Furthermore, the study illustrates the importance of avoiding low-contrast visual stimulation patterns obtained with LCD as they lead to higher latencies resulting in false positive recordings. These findings are important when establishing or modifying a pattern VEP recording protocol.

Abstract:
In recent years there has been an increase in the number of students wanting to record lectures. Two factors have contributed to this. Firstly, there is wide availability of compact, solid state recorders, and recorders are often incorporated into other goods (MP3 players, mobile phones, cameras, laptops). Secondly, within many universities facilities have been provided by student support services for students with a special need to record lectures.However, the recording of lectures presents a number of issues related to ownership, data protection, potential misuse, and the pedagogic issue of ensuring equal treatment for all students. University recording policies address some of these issues, but the individual academic also needs to reflect on the consequences for their teaching.A trial has been carried out offering streamed recordings of lectures, and the merits of streaming and downloading are discussed. A survey was made on the usage by students and their reasons for accessing the recordings, and these are reported. There have been a number of advantages to students as well as to the lecturer which have required relatively little extra burden on the lecturer. One important initial conclusion appears to be the need to incorporate recordings as part of the teaching material in the initial pedagogic design rather than an addition. For some students the recordings have proved a valuable additional resource and feedback from students has been positive.

Abstract Fluid-coupled recording systems are the most popular method of recording intracranial pressure (ICP), but they can be prone to blockage and infection. A series of 378 recordings of ICP was analyzed to identify complications and cases in which recording had to be discontinued prematurely because of catheter blockage. Three different methods of ICP recording were used: a ventricular catheter, a Richmond screw, and a subdural catheter. Richmond screws became blocked more often (16%) than subdural catheters (2.7%) or ventricular catheters (2.5%). Complications of infection and intracerebral hemorrhage were observed mostly in the ventricular catheter patients. Of these three methods, a subdural catheter is the preferred method of recording ICP.

Abstract:
Microelectrode array recordings of neuronal activity present significant opportunities for studying the brain with single-cell and spike-time precision. However, challenges in device manufacturing constrain dense multisite recordings to two spatial dimensions, whereas access to the three-dimensional (3D) structure of many brain regions appears to remain a challenge. To overcome this limitation, we present two novel recording modalities of silicon-based devices aimed at establishing 3D functionality. First, we fabricated a dual-side electrode array by patterning recording sites on both the front and back of an implantable microstructure. We found that the majority of single-unit spikes could not be simultaneously detected from both sides, suggesting that in addition to providing higher spatial resolution measurements than that of single-side devices, dual-side arrays also lead to increased recording yield. Second, we obtained recordings along three principal directions with a multilayer array and demonstrated 3D spike source localization within the enclosed measurement space. The large-scale integration of such dual-side and multilayer arrays is expected to provide massively parallel recording capabilities in the brain.

Abstract:
Field sound recordings are an indispensable source of data for ethnomusicologists. However, to my knowledge there are no standards or guidelines of how this data should be captured and managed. With the progress made in machine learning, it has become vital to record data in a way that also supports the retrieval of information about the music. This article describes a model developed for field recordings that aims to aid an objective data gathering process. This model, developed through an action research process that spanned multiple field recording sessions from 2009–2015, include recording equipment, production processes, the gathering of metadata as well as intellectual property rights. The core principles identified in this research are that field recording systems should be designed to provide accurate feedback as a means of quality control and should capture and manage metadata without relying on secondary tools. The major findings are presented in the form of a checklist that can serve as a point of departure for ethnomusicologists making field recordings.

Abstract:
Our study tests the acoustic fidelity of remote recordings, using a large variety of stimuli and recording environments. With standard recording environments not available due to COVID-19, more studies investigate remote recordings for acoustic analyses [e.g., Guan and Li (2021); Freeman and De Decker (2021)]. High fidelity remote recordings also support crucial uses like reaching isolated populations and more speakers. A 188-word list was constructed from each English consonant followed by each vowel. Words recorded by a male and female speaker in a sound attenuated booth were input for test recordings. Stimuli were recorded on six devices across five operating systems, four tele-conferencing platforms, and three browsers, using internal and external microphones. Acoustic analysis investigates the impact of these recording configurations on features including pitch, relative intensity, vowel formant measures, spectral moments, spectral tilt, spectral rolloff, and Mel Frequency Cepstral Coefficients. Preliminary analyses found durational differences between original and test-recorded stimuli, posing challenges for automatic segmentation and alignment. Aperiodic noise was also introduced. We hypothesize further distortions in other measures. The findings from this study will allow us to identify acoustic measures which are robust across varied remote recording conditions and to highlight configurations least likely to introduce problematic artifacts.

Abstract:
Increasing demand for remote research techniques has led to several initial investigations of the suitability of remote recording for vowel production research. An initial consensus has emerged that remote recording may provide broadly accurate data for broad-strokes analysis, such as analyzing the relative positions of a speaker’s vowels, although some minor distortions may occur; fine-grained analysis of sociolinguistic variation suffers greatly from remote data collection (Freeman and De Decker, 2021). This study investigates the quality of data obtainable through two remote recording methods (online recording through Gorilla and offline recording via smartphone) for a vocalic phenomenon requiring a medium level of sensitivity of analysis, namely vowel reduction. Ten subjects completed a shadowing task eliciting target words containing one of five English vowels in reduced or unreduced form, taking simultaneous online and offline remote recordings. To determine whether the variability introduced through the remote recording process was sufficient to alter the findings of the study, results were compared to data from a second group of subjects who completed the task in person in a traditional laboratory setting. This comparison to in-person data allows for an assessment of the suitability of online and offline remote recordings for vowel reduction research.

Abstract:
Eye movement has become a new behavioral feature for biometric authentication. In the eye movement-based authentication methods that use temporal features and artificial design features, the required duration of eye movement recordings are too long to be applied. Therefore, this study aims at using eye movement recordings with shorter duration to realize authentication. And we give out a reasonable eye movement recording duration that should be less than 12 s, referring to the changing pattern of the deviation degree between the gaze point and the stimulus point on the screen. In this study, the temporal motion features of the gaze points and the spatial distribution features of the saccade are using to represent the personal identity. Two datasets are constructed for the experiments, including 5 s and 12 s of eye movement recordings. On the datasets constructed in this paper, the open-set authentication results show that the Equal Error Rate of our proposed methods can reach 10.62% when recording duration is 12 s and 12.48% when recording duration is 5 s. The closed-set authentication results show that the Equal Error Rate of our proposed methods can reach 5.25% when recording duration is 12 s and 7.82% when recording duration is 5 s. It demonstrates that the proposed method provides a reference for the eye movements data-based identity authentication.

Abstract:
Nowadays, the classic diagnostic method to monitor general foetus well-being using the foetal heart rate conditions, ultrasonic cardiotography, is called into question. A valuable alternative is foetal phonocardiography, a passive and low-cost recording of foetal heart sounds. This paper presents a software which generates synthetic foetal phonocardiographic recordings simulating different recording conditions (by modifying noise level). From a real foetal phonocardiographic recording this software calculates the foetal heart rate. The software was developed using information picked from the literature especially for identifying the waveforms and characteristics of foetal and maternal heart sounds, and the different noises involved in real phonocardiographic recordings. Considering the possibility to simulate different recording situations and physiological or pathological foetal conditions just by modifying some parameters, this simulator software can be useful for testing different foetal-heart-rate extraction algorithms, like the authors’ one. In this paper are presented the different postulates used for developing this software.

Abstract:
AbstractIn this article I emphasise the deliberate and reflexive way that Bob Dylan has approached studio recording, sketching the features of a phonographic aesthetic, to highlight a neglected aspect of Dylan's creative practice and to counter the view of Dylan as primarily a ‘performing artist’, one who approaches the studio in a casual manner as a place to cut relatively spontaneous drafts of songs that are later developed on stage. Drawing on Evan Eisenberg's discussion of the ‘art of phonography’ and the way recording radically separates a performance from its contexts of ‘origin’ (allowing recordings to be taken into a private space and subjected to intense, repeated listening), I argue that studio practice, a recording aesthetic and the art of phonography are integral to Dylan's songwriting. The process and practice of songwriting is realised through the act of recording and informed by listening to songs and performances from recordings, regardless of how much time is actually spent in the studio. Exploring how Dylan's phonographic imagination has been shaped by folk, blues and pop sonorities, along with film music, I argue that recording should be integrated into discussions of Dylan's art, alongside the attention devoted to lyrics, performance and biography.

Abstract:
We describe our misgivings concerning the use of transcripts of covert recordings of medico-legal assessments made by claimants as evidence in actions for compensation for personal injury. These recordings raise issues of lack of trust between the claimant and the medical expert, leading to bias in the consultation that is hidden from the medical expert. In addition, there is a risk of widespread dissemination of the recording through social media to the detriment of the reputation of the medical expert, and likely interference with the probity of the court hearing. We argue that the claimant and the medical expert have equal rights to privacy within a medical or medico-legal consultation, and recordings should not be made without mutual agreement. Furthermore, the courts should rely only on the report of the medical expert since a recording of the consultation represents only part of the process of medical assessment. We argue that the current advice given by the General Medical Council on covert recording of medical or medico-legal consultations should be reconsidered by a panel of experienced medical and legal experts.

Abstract:
Recordings of cougar (Puma concolor) vocalizations are rare in the wild. We made two night recordings from the same individual. The first recording was spontaneous whereas the second was made after a playback emission (using a third party recording) allowing for comparisons. We measured the calls before and after playback stimuli using Raven software and noted that only the minimum fundamental frequency presented differences between calls. As fundamental frequency is closely related to body size, a frequency reduction may indicate territoriality engagement. Our recording seems to be the first held in the Brazilian wild. Little is known about cougar natural history and behavior, and our data suggest that acoustic communication may have an important role on the species intraspecific interactions.

Abstract:
The Xenopus tadpole visual system shows an extraordinary extent of developmental and visual experience–dependent plasticity, establishing sophisticated neuronal response properties that guide essential survival behaviors. The external development and access to the developing visual circuit of Xenopus tadpoles make them an excellent experimental system in which to elucidate plastic changes in neuronal properties and their capacity to encode information about the visual scene. The temporal structure of neural activity encodes a significant amount of information, access to which requires recording methods with high temporal resolution. Conversely, elucidating changes in the temporal structure of neural activity requires recording over extended periods. It is challenging to maintain patch-clamp recordings over extended periods and Ca2+ imaging has limited temporal resolution. Extracellular recordings have been used in other systems for extended recording; however, spike amplitudes in the developing Xenopus visual circuit are not large enough to be captured by distant electrodes. Here we describe a juxtacellular tetrode recording method for continuous long-term recordings from neurons in intact tadpoles, which can also be exposed to diverse visual stimulation protocols. Electrode position in the tectum is stabilized by the large contact area in the tissue. Contamination of the signal from neighboring neurons is minimized by the tight contact between the glass capillaries and the dense arrangement of neurons in the tectum. This recording method enables analysis of developmental and visual experience–dependent plastic changes in neuronal response properties at higher temporal resolution and over longer periods than current methods.

AbstractThe performances of Ernő Dohnányi as pianist and conductor were preserved on numerous sound recordings. He was involved in the recording industry first in 1905, and his death was notoriously caused by a cold suffered in a recording studio in 1960. His interpretation is preserved on different audio media: piano rolls, 78rpm and Long Play discs, x-ray foils and reel-to-reel tapes. Although the number of his studio recordings, made for commercial purposes, is relatively small, the amount of live concert and home recordings, including the huge collection of unpublished recordings made in the USA between 1945 and 1960, expands it to a significant corpus of sound recordings. This article contains the complete discography of Ernő Dohnányi as a performer. The discography provides all available data of the studio and live recordings of Dohnányi, including the data of reissues (closing date: June 2022). It is preceded by an article in which Dohnányi's discography is analysed from several aspects. The analysis of the recorded repertoire sets the stage for further research on Dohnányi's interpretation; however, lost recordings are also reviewed. Dohnányi's controversial relationship to the technical media, and vice versa the recording firms changing interest in him as a performer, are also discussed in detail, involving several sources formerly unknown to Dohnányi research.

Object. The goal of this study was to determine the usefulness of electromyographic (EMG) recording in locating motor pathways near the central sulcus or internal capsule during surgery.Methods. Multichannel EMG recordings were compared with visual observation of contralateral body movement that was elicited by direct cortical or subcortical stimulation used to identify motor pathways before and during tumor resection.The EMG recordings were more sensitive than visual observation alone in identifying motor responses: in 30% of cases, responses were identified by EMG recording alone at some point during the operation and, in 9% of cases, EMG responses were the only responses observed. Additionally, EMG recordings often detected seizure activity resulting from electrical stimulation of the cortex that could not be appreciated on visual inspection. No new motor deficits were seen postoperatively in 88% of the patients in this series.Conclusions. Using EMG recording in addition to motor pathway mapping results in greater sensitivity, allowing the use of lower stimulation levels and facilitating detection of stimulation-induced seizure activity.

Abstract:
AbstractLo-fi music is commonly associated with a recording aesthetic marked by an avoidance of state-of-the-art technologies and an inclusion of technical flaws, such as tape hiss and static. However, I argue that lo-fi music is not defined merely by the presence of such imperfections, but by a discourse which deliberately draws attention to them. Album liner notes play an important role in this discourse, as they can function as curatorial practices, through which lo-fi artists give an appropriate frame of reference to their recordings. By highlighting the ‘honest’ character of the recordings, the intimate recording spaces, the materiality of the equipment and its ambiguous character as machine/instrument/performer, they invite listeners to adopt a genre-adequate mode of listening. Rather than listening past hiss and other recording artefacts as undesirable qualities, listeners are asked to listen for these qualities as an essential element of not just the recordings, but the music itself.

290 Background: The high prevalence of smartphone use means that most patients can easily audio record medical consultations. Oncologists’ attitudes towards recording visits are unknown yet may impact patient care. Methods: A mail survey of oncologists practicing at 5 U.S. Alliance for Clinical Trials in Oncology sites collected information on clinicians’ beliefs, preferences, and practices regarding patient-initiated recordings, along with sociodemographic and practice characteristics. Descriptive statistics and bivariate analyses were calculated. Results: Of 523 eligible oncologists, 352 (67%) completed the survey. Median age was 47 years, 33% were female, and 86% worked in an academic setting. 53% were medical oncologists, 30% surgical oncologists, and 17% radiation oncologists. Virtually all (93%) reported experience with patients recording visits, 79% at least weekly. The majority (74%) perceived that patients record visits in order to help understand treatment choices. While 79% reported that they “always” agree to recordings, 26% reported discomfort. Nearly one-third (29%) reported concerns about liability, 26% felt recording made discussion less natural, and 18% felt recording changed the way they conveyed information. Although 86% agreed that patients have the right to record visits, nearly all felt physician permission was required and 53% reported having been previously recorded without permission. Only 51% believed recording had a positive impact on the patient-doctor relationship. One-quarter (28%) felt that recording led to a less detailed conversation and 33% felt it contributed to avoidance of difficult topics, such as prognosis. Most preferred the patient/family taking notes or having access to a written summary. Views did not vary significantly based on practice setting, specialty, or region of the country. Older age and greater years in practice were associated with both greater comfort with recording and the perception that recording has a positive impact on the patient-doctor relationship (p < 0.001). Conclusions: While most oncologists report comfort with audio recording and recognize benefits for patients, a substantial minority have reservations about its impact on clinical discussions and their liability exposure. Adopting clear institutional policies about recording could help address some concerns, such as surreptitious recording, while ensuring that patients’ interests are served.

Abstract:
We compared the dynamic cerebral autoregulation (dCA) indices between 5- and 10-minute data lengths by analyzing 37 patients with ischemic stroke and 51 controls in this study. Correlation coefficient (Mx) and transfer function analysis were applied for dCA analysis. Mx and phase shift in all frequency bands were not significantly different between 5- and 10-minute recordings [mean difference: Mx = 0.02; phase shift of very low frequency (0.02–0.07 Hz) = 0.3°, low frequency (0.07–0.20 Hz) = 0.6°, and high frequency (0.20–0.50 Hz) = 0.1°]. However, the gains in all frequency bands of a 5-minute recording were slightly but significantly higher than those of a 10-minute recording (mean difference of gain: very low frequency = 0.05 cm/s/mmHg, low frequency = 0.11 cm/s/mmHg, and high frequency = 0.14 cm/s/mmHg). The intraclass correlation coefficients between all dCA indices of 5- and 10-minute recordings were favorable, especially in Mx (0.93), phase shift in very low frequency (0.87), and gain in very low frequency (0.94). The areas under the receiver operating characteristic curve for stroke diagnosis between 5- and 10-minute recordings were not different. We concluded that dCA assessed by using a 5-minute recording is not significantly different from that using a 10-minute recording in the clinical application.

Abstract:
In recent years, performance management (PM) has become a buzzword in public sector organizations. Well-functioning PM systems rely on valid performance data, but critics point out that conflicting rationale or logic among professional staff in recording information can undermine the quality of the data. Based on a case study of social service staff members, the authors explore three recording logics. The findings reveal a complexity of recording behavior and show how frontline staff shift between recording logics according to the situation. The actual data recordings depend not only on the overall logic but also on factors such as attitudes, assumptions, and motives. The authors suggest that shifting recording logics weaken the validity of performance data. These shifts undermine the idea of PM as a trustworthy strategy to bridge the gap between professional and managerial staff, as well as the possibility of a well-informed management.

Abstract:
Recordings of the physiological history of cells provide insights into biological processes, yet obtaining such recordings is a challenge. To address this, we introduce a method to record transient cellular events for later analysis. We designed proteins that become labeled in the presence of both a specific cellular activity and a fluorescent substrate. The recording period is set by the presence of the substrate, whereas the cellular activity controls the degree of the labeling. The use of distinguishable substrates enabled the recording of successive periods of activity. We recorded protein-protein interactions, G protein–coupled receptor activation, and increases in intracellular calcium. Recordings of elevated calcium levels allowed selections of cells from heterogeneous populations for transcriptomic analysis and tracking of neuronal activities in flies and zebrafish.

Abstract:
Abstract Objective. Neuromodulation of visceral nerves is being intensively studied for treating a wide range of conditions, but effective translation requires increasing the efficacy and predictability of neural interface performance. Here we use computational models of rat visceral nerve to predict how neuroanatomical variability could affect both electrical stimulation and recording with an experimental planar neural interface. Approach. We developed a hybrid computational pipeline, Visceral Nerve Ensemble Recording and Stimulation (ViNERS), to couple finite-element modelling of extracellular electrical fields with biophysical simulations of individual axons. Anatomical properties of fascicles and axons in rat pelvic and vagus nerves were measured or obtained from public datasets. To validate ViNERS, we simulated pelvic nerve stimulation and recording with an experimental four-electrode planar array. Main results. Axon diameters measured from pelvic nerve were used to model a population of myelinated and unmyelinated axons and simulate recordings of electrically evoked single-unit field potentials (SUFPs). Across visceral nerve fascicles of increasing size, our simulations predicted an increase in stimulation threshold and a decrease in SUFP amplitude. Simulated threshold changes were dominated by changes in perineurium thickness, which correlates with fascicle diameter. We also demonstrated that ViNERS could simulate recordings of electrically-evoked compound action potentials (ECAPs) that were qualitatively similar to pelvic nerve recording made with the array used for simulation. Significance. We introduce ViNERS as a new open-source computational tool for modelling large-scale stimulation and recording from visceral nerves. ViNERS predicts how neuroanatomical variation in rat pelvic nerve affects stimulation and recording with an experimental planar electrode array. We show ViNERS can simulate ECAPS that capture features of our recordings, but our results suggest the underlying NEURON models need to be further refined and specifically adapted to accurately simulate visceral nerve axons.
