AES69-2022: AES standard for file exchange - Spatial acoustic data file format
Printing Date: 2022-09-02
Publication History: Pub. 2015, Revised 2020, Revised 2022
Abstract: Binaural listening is growing fast, because of growing sales in smartphones, tablets and other individual entertainment systems. The lack of a standard for the exchange of head-related transfer functions (HRTF) means each company keeps its binaural capture and rendering algorithms private. 3D audio is arising, and binaural listening could be the very first 3D audio vector with sufficient fidelity of HRTF. The use of convolution-based reverberation processors in 3D virtual audio environments has grown with the increase in available computing power. Convolution-based reverberators guarantee an authentic and natural listening experience, but also depend on the acoustic quality of the applied spatial room impulse response (SRIR). With a standardized file format for HRTF and SRIR data, each company can contribute its best algorithms, providing good personalized capture and/or rendering, allowing the consumer to choose a combination of technologies for the best quality of experience. This document standardizes a file format to exchange space-related acoustic data, such as binaural listening parameters in the form of head related transfer functions. The format is scalable to match the available rendering process and is designed to include source materials from different databases.
