Motivations: In general, audio signals can be music, speech or a mix of both. Across applications, the bitrates available in transmission channels can vary greatly. Hence, this work addresses the need to provide high compression for signals that are a mix of music and speech.
Objectives: To create compression technology that provides high performance over a wide range if bit rates. Specifically, to code mono signals at 12 kb/s, stereo signals from 16 kb/s and 5.1 channel signals at 96 kb/s.
