Abstract
An audio filterbank coder using both monophonic and stereophonic redundancy and irrelevancy is described. This coder, with a transform filterbank, uses both signal-processing gains and perceptual gains to provide transparent or nearly transparent coding of CD and R-DAT audio signals at 192 kb/s/stereo pair, and high-quality coding at 128 kb/s/stereo pair. Methods of using the interchannel redundancies and psychoacoustic characteristics are described.<>Keywords
