A Backward-Compatible Multichannel Audio Codec
We propose in this paper a backward-compatible multichannel audio codec. This codec represents a multichannel audio input signal by a down mix and parametric data. In order to enab...

Low bitrate audio coding using generalized adaptive gain shape vector quantization across channels
Audio coding at low bitrates suffers from artifacts due to spectrum truncation. Typical audio codecs code multi-channel sources using transforms across the channels to remove redu...
