Audio Time Stretching with Controllable Phase Coherence

This paper presents a hybrid audio time stretching technique in which the trade-off between vertical and horizontal phase coherence can be freely controlled by a single parameter. Depending on that parameter, the proposed technique sounds like a time domain technique at one extreme, like a phase-locked vocoder at the other extreme, or anywhere in between. By properly choosing the value of the control parameter, it is possible to manually adjust the algorithm to the characteristics of the audio signal being transformed in order to get an optimal result. Furthermore, appropriate middle values yield good results for a wide range of audio signals with mixed content.
