This standard describes a set of speech and audio compression, decompression and packaging tools and mechanism. It is applicable to the following areas: Mobile communication; Wireless broadband multimedia; communication; Internet broadband streaming media business
Purpose
This standard provides regular low-bit rate speech and audio-coding tool sets for wireless and mobile speech and audio compression and decompression. It provides error masking ability, supports stereo effect, supports wideband audio quality and saves bandwidth for wireless transmission and mobile communication and memory space for storage.
Abstract
New IEEE Standard - Active.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.
