Project AES-X213, MADI over twisted-pair cabling, has been initiated.
This project seeks to add twisted pair connectivity to AES10 in addition to the current connectivity options.
A twisted-pair interconnection should lead to further simplification of multichannel audio connectivity and significant cost reductions. 1. Interface cost reduction allowing for use in low and high channel capacity applications. 2. Allows use of commonly available Category 5 (or better) cabling infrastructures. 3. Smaller footprint for device connectors, allowing for high density connectivity. 4. Easier implementation, as the most of the coding is done by a cost effective and readily available Ethernet PHY. 5. Galvanic isolation for copper based AES10 interfaces. 6. Guarantees immunity from obsolete, boutique and expensive components 7. Optionally allows for standardized control using 10/100MB Ethernet on the same cable/connector as MADI. 8. Optionally allows for devices to be remote power over the interface using PoE phantom power.

Project AES-X212, HRTF file format, has been initiated.
This project seeks 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.
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's data is unreadable by others.
Interest in 3D audio is rising, 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.
