James D Johnston: Method and apparatus for coding audio signals based on perceptual model. AT&T Bell Laboratories, William Ryan, February 8, 1994: US05285498 (229 worldwide citation)

Coding of high quality stereophonic audio signals is accomplished in a perceptual filterbank coder which exploits the interchannel redundancies and psychoacoustic. Using perceptual principles, switching between a normal and short window of input samples improve output signal quality for certain inpu ...
