Dirk Jeroen Breebaart, Arnoldus Werner Johannes Oomen: Audio coding. Koninklijke Philips Electronics, February 20, 2007: US07181019 (33 worldwide citation)

Parametric stereo coders use perceptually relevant parameters of the input signal to describe spatial properties. One of these parameters is the phase difference between the input signals (ITD or IPD). This time difference only determines the relative time difference between the input signals, witho ...
