Actual head position relative to the torso is found for 195 persons. The effect of the head position in HRTF is studied by modifying the 3D model of a Kemar head-and-torso simulator geometry by translating the head relative to torso in up-down and forward-backward directions and rotating the torso. The spectral difference is compared to that seen in the closest matching actual persons. Forward-backward location of the head has the strongest influence in the HRTF. The spectral difference between the fixed and rotated torso spectra can exceed a 1-dB limit for all sound arrival azimuth directions when the torso rotation exceeds 10°. The spectral difference decreases with increasing source elevation. A subjective listening test with personal HRTF demonstrates that the spectral effect of the torso rotation are audible as a sound color and location changes. The HRTF data in this work is found by calculating the sound field using the boundary element method and the 3D shape of the person acquired using photogrammetry.","PeriodicalId":50008,"journal":{"name":"Journal of the Audio Engineering Society","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141826125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methods are applied to an array of five microphones whose signals were simulated for static and dynamic array orientations. Methods under test involve scene-agnostic binaural reproduction methods as well as methods that have knowledge of (a subset of) source directions. The results of an instrumental evaluation reveal errors in the reproduction of interaural level and time differences for all scene-agnostic methods, which are smallest for the end-to-end magnitude-least-squares method. Additionally, the inherent localization robustness of the array under test and different simulated microphone arrays is investigated and discussed, which is of interest for a parametric reproduction method included in the study. In the listening experiment, the end-to-end magnitude-least-squares reproduction method outperforms other scene-agnostic approaches. Above all, linearly constrained beamformers using known source directions in combination with the end-to-end magnitude-least-squares method outcompete the scene-agnostic methods in perceived quality, especially for a rotating microphone array under anechoic conditions.","PeriodicalId":50008,"journal":{"name":"Journal of the Audio Engineering Society","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141824152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The management of many microphone signals and monitoring of various broadcast feeds mean engineers are often stretched, overseeing many tasks simultaneously. With the advancements in Next Generation Audio codecs providing many appealing features, such as interactivity and personalization to end users, consideration is needed as not to create further work for production staff. Therefore, the authors propose a novel approach to live sports production by combining an object-based audio workflow with the efficiency benefits of automated mixing. This paper describes how a fully object-based workflow can be built from point of capture to audience playback with minimal changes for the production staff. This was achieved by integrating Next Generation Audio authoring from the point of production, streamlining the workflow, and thus removing the need for additional authoring process later in the chain. As an exemplar, the authors applied this approach to a Premier League football match in a proof-of-concept trial.","PeriodicalId":50008,"journal":{"name":"Journal of the Audio Engineering Society","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141826952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through measurements of the binaural room transfer functions in a practical PSZ system with either translational or rotational movements of one of the two mannequin listeners, the PSZ filters were generated along the measurement grid and then spatially downsampled to different resolutions, at which the isolation performance of the system was numerically simulated. It was found that the spatial sampling resolution generally depends on factors such as the moving listener’s position, frequency band of the rendered audio, and perturbation caused by the other listener. More specifically, the required sampling resolution is inversely proportional to the distance either between two listeners or between the moving listener and the loudspeakers and is proportional to the frequency of the rendered audio. The perturbation caused by the other listener may impair both the isolation performance and filter robustness against movements. Furthermore, two crossover frequencies were found to exist in the system, which divide the frequency band into three sub-bands, each with a distinctive requirement for spatial sampling.","PeriodicalId":50008,"journal":{"name":"Journal of the Audio Engineering Society","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141827122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It presents the results of a dual-stage study, which utilized focus groups with eight professional music producers and a questionnaire completed by 140 practitioners. Analysis revealed the continued influence of stereo approaches on mix engineers, partly due to its historical dominance as a production platform and consumers’ continued use of headphones. It was also found that core elements of popular music productions, such as snare drums, tom-tom drums, kick drums, bass guitars, main guitars, and vocals, were less likely to have binaural processing applied compared with other sources. It was also shown there were perceived differences in the suitability of spatial audio mixing for specific genres, with electronic dance music, jazz, pop, classical, and world music rated as the most suitable. Regarding the binaural renderers, there was less user satisfaction with the Apple device compared with Dolby’s, and this dissatisfaction manifested mainly in the need for more user control. Finally, mix engineers were very aware of the importance of their mixes translating to smaller speaker systems and headphone playback, in particular.","PeriodicalId":50008,"journal":{"name":"Journal of the Audio Engineering Society","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141827633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interruptions can be detrimental to performance of the ongoing, interrupted task. Designers often can choose whether interruptions are delivered as visual or auditory alerts. Contradictory theories have emerged regarding whether auditory or visual alerts are more harmful to performance of ongoing visual tasks. Multiple Resources Theory predicts better overall performance with auditory alerts, but Auditory Preemption Theory predicts better overall performance with visual alerts. Nees and Sampsell previously found that multitasking was superior with nonspeech auditory alerts as compared to visual alerts. In the current experiment, their methods were replicated and extended to include a speech auditory alerts condition. Performance of the ongoing tracking task was worse with interruption from visual alerts, and perceived workload also was highest in this condition. Reaction time to alerts was fastest with visual alerts. There also was converging evidence to suggest that performance with speech alerts was superior to performance with nonspeech tonal alerts. The current experiment replicated the results of Nees and Sampsell and extended their findings to speech alert sounds. Like in their study, the pattern of findings here support Multiple Resources Theory over Auditory Preemption Theory.","PeriodicalId":50008,"journal":{"name":"Journal of the Audio Engineering Society","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141015505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
