MPEG-I Immersive Audio supports bitrate-efficient and high-quality storage/transmission of complex virtual scenes including sources with spatial extent and distinct radiation characteristics (like musical instruments) as well as geometry description of acoustically relevant elements (e.g., walls, doors, occluders). The rendering process includes detailed modeling of room acoustics and complex acoustic phenomena such as occlusion and diffraction due to acoustic obstacles and Doppler effects as well as interactivity with the user. Based on many contributions, this paper reports on the state of the MPEG-I Immersive Audio standardization process and its first technical Reference Model architecture. MPEG-I Immersive Audio establishes the first long-term stable audio format specification in the field of VR/AR and can be used for many consumer applications such as broadcasting, streaming, social VR/AR, or Metaverse technology.","PeriodicalId":50008,"journal":{"name":"Journal of the Audio Engineering Society","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42417044","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 is yet unclear whether the directivity variation as a function of the played tone leads to a perceptible difference compared to an auralization that uses an averaged directivity pattern. This paper examines the directivity of 38 musical instruments from a publicly available database and then selects three representative instruments among those with similar radiation characteristics (oboe, violin, and trumpet). To evaluate the listeners’ ability to perceive a difference between auralizations of virtual environments using tone-dependent and averaged directivities, a listening test was conducted using the directivity patterns of the three selected instruments in both anechoic and reverberant conditions. The results show that, in anechoic conditions, listeners can reliably detect differences between the tone-dependent and averaged directivities for the oboe but not for the violin or the trumpet. Nevertheless, in reverberant conditions, listeners can distinguish tone-dependent directivity from averaged directivity for all instruments under study.","PeriodicalId":50008,"journal":{"name":"Journal of the Audio Engineering Society","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43673443","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}

A sufficient number of VRS and adequate spatial mapping are required to approximate spatially anisotropic late reverberation, e.g., in rooms with inhomogeneous distribution of absorption or for coupled volumes. For coupled rooms, moreover, a dual-slope decay might be required. Here, an efficient and perceptually plausible method to generate and spatially render late reverberation is suggested. Incoherent VRS signals for (sub-) volumes are generated based on room dimensions and frequency-dependent absorption coefficients at the boundaries. For coupled rooms, (acoustic) portals account for effects of sound propagation and diffraction at the room connection and energy transfer during the reverberant decay process. The VRS are spatially distributed around the listener, with weighting factors representing the spatially subsampled distribution of absorption on the boundaries and the location and solid angle covered by portals. A technical evaluation and listening tests demonstrate the validity of the approach in comparison to measurements in real rooms.","PeriodicalId":50008,"journal":{"name":"Journal of the Audio Engineering Society","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46550341","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}
