Revision Standard - Active. A set of tools to support specific audio coding functions including general audio coding and lossless audio coding are defined in this standard. The tool set defined in combination provides regular high-quality and efficient coding tool sets for compression, decompression, processing, and representing of audio data to save bandwidth for transmission; to save space for storage; to speed up indexing and multimedia search; and to enhance performance when using mixed media for virtual reality and other applications that demand high bandwidth. The target applications and services include but are not limited to audio transmission, audio recording, Internet streaming, and other video/audio-enabled services and applications.
This standard specifies the audio compression, decompression and packaging tools and mechanism to support the transmission and store of the multimedia data over the Internet in a highly efficient way. It can realize more efficient lossless compression than ALS m21 (BGMC1024) and the decoding speed is faster than EH-APE, and coding tool can be selected by taking into account compression efficiency and complexity.
This standard provides regular high-quality and efficient coding tool sets for compression, decompression and packaging of multimedia data to save bandwidth for transmission on the Internet or space for storage.
