High Quality Multi-channel Time-Scaling and Pitch-Shifting Using Auditory Scene Analysis

A method of using auditory scene analysis of audio signals in conjunction with time and pitch scaling is presented. In the method described, a multi-channel audio signal is analyzed and the location and duration of the individual audio signal components that correspond to distinct auditory scene elements are identified. The audio data is then time and/or pitch scaled in such a way that the separate audio signal components are processed individually, thereby greatly reducing audible artifacts inherent in time and pitch scaling processing.
