Project AES-X212 initiation

[page updated 2012-10-16]

This project was proposed by Matthieu Parmentier. It was approved under our rules by Subcommittee SC-02 and assigned to the working group SC-02-08 on Working Group on Audio File Interchange.

TITLE AES-X212, HRTF file format
SCOPE to standardize a file format to exchange binaural listening parameters in the form of head related transfer functions (HRTF). The format will be scalable to match the available rendering process. The format will be designed to include source materials from different HRTF databases.
RATIONALE Binaural listening is growing fast, because of growing sales in smartphones, tablets and other individual entertainment systems. The lack of a standard for HRTF exchange 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. With a standardized HRTF file format, each company could contribute its best algorithms, providing good personalized capture and/or rendering, allowing the consumer to choose its best combination of technologies for the best quality of experience.
WHO BENEFITS? 3D audio consumers who will have a more reliable 3D experience. Developers of 3D audio systems and services who use the standard to access more consumers.
WHY AES? The AES has the capacity to write and publish a real standard.
