IEEE P1857.5

Revision Standard - Active - Draft.
A set of tools to support specific audio coding functions including ACELP/TVC compression, bandwidth extension, stereo coding, frame erasure concealment, etc. is defined in this standard. The tool set defined in this standard provides high quality and efficient coding tool sets for compression, decompression, processing, and representation of speech, music or mixed audio signals to save transmission bandwidth and storage space. The target applications and services include but not limited to mobile communication, wireless broadband multimedia communications, internet broadband streaming media service and applications.

This standard outlines a set of tools for speech and audio compression, decompression and packaging tools, and supporting features like wide-band audio quality at low bit-rates, stereo effect, and error concealment. It is applicable to mobile communication, wireless multimedia, and internet streaming.
The standard provides a regular toolset for efficient speech and audio coding at low bit-rates, facilitating bandwidth optimization in wireless and mobile networks and storage space optimization.
