AB  - Multichannel audio is increasingly ubiquitous in consumer audio applications such as satellite radio broadcast systems, surround sound playback systems, multichannel audio streaming and other emerging applications. These applications often present a challenging bandwidth constraint making parametric multichannel coding schemes attractive. Several techniques have been proposed recently to address this problem. Here we present a novel low bit rate 5 channel encoding system that has shown promising results. This technique called the Immersive Soundfield Rendition (ISR) System emphasizes accurate reproduction of multi-band temporal envelope. The ISR system also incorporates a very low over-head (blind upmixing) mode. The proposed multichannel coding system has yielded promising results for multi-channel coding in the 0-12 kbps range.
