TC32-TG22 - Scalable Sparse Spatial Sound System (S5)

Scope - Programme of work - Activities

Scope:

To develop Standards and Technical Reports for a digital spatial audio system which uses Inverse Coding to achieve highly efficient coding of localization and ambiance information.

Programme of work:

1. To develop and maintain Standards/Technical Reports for an Inverse Coding based audio system covering:
   • Requirements on data formats and preprocessing of the audio source
   • Overall S5 architecture
   • Coding format of Inverse Coding parameter data
   • Recommendations/References regarding Base audio encoders
   • Multiplexing of base audio stream and Inverse Coding parameter data
     a) External multiplexing
     b) Internal multiplexing by embedding Inverse Coding parameter data in audio stream.
2. To develop and maintain Standards/Technical Reports on binaural rendering with Head Related Transfer Functions (HRTF).
3. To develop and maintain Standards/Technical Reports on highly efficient/low power binaural rendering with Head Related Transfer Functions (HRTF).
4. To develop and maintain Standards/Technical Reports on conformance testing tools for implementations.
5. To develop and maintain Standards/Technical Reports on quality testing tools for implementations.
6. To cooperate and liaise with Ecma TCs and external organizations and standardisation bodies working in related technical fields (e.g. ISO/IEC JTC 1/SC 29/WG 11 (MPEG)).
