At its 150th meeting, MPEG promoted three standards (among others) to Final Draft International Standard (FDIS), driving innovation in immersive audio and video coding:
- MPEG-H 3D audio
- MPEG-H 3D audio reference software
- MPEG-I Immersive audio reference software
At the 150th MPEG meeting, MPEG Technical Requirements (WG 2) issued a Call for Proposals (CfP) for technologies and solutions enabling efficient compression for audio coding for machines. Traditional coding methods aim for the best audio under certain bit-rate constraint for human consumption. MPEG-ACoM aims to define a bitstream and data format for compressing audio, multi-dimensional streams, or features extracted from such signals that is efficient in terms of bitrate/size and can be used for machine analysis tasks or hybrid machine and human consumption. In addition, such a data format can be used to transport recorded audio data from sensor networks to machine listening units. Applications for machine listening are in industrial, surveillance, control, medical, and multimedia applications. This call focuses on lossless audio coding enabling the use of the same compression scheme for all applications. This CfP welcomes submissions of proposals from companies and other organizations. Registration is required by the 1st of August 2025; the submission of bitstream files, results, and decoder packages is required by the 1st of September 2025; and the submission of proponent documentation is due by the 26th of September 2025. Evaluation of the submissions in response to the CfP will be performed at the 152th MPEG meeting in October 2025.
