INTER-CHANNEL ENCODING AND DECODING OF MULTIPLE HIGH-BAND AUDIO SIGNALS

Abstract:

A device includes an encoder configured to generate a first high-band portion of a first signal based on a left signal and a right signal. The encoder is also configured to generate a set of adjustment gain parameters based on a high-band non-reference signal and a synthesized signal. The high-band non-reference signal corresponds to one of a left high-band portion of the left signal or a right high-band portion of the right signal.
