This MATLAB exercise implements the Waveform Similarity and Overlap Add (WSOLA) method of Verhelst and Roelands (An Overlap-Add Technique Based on Waveform Similarity (WSOLA) for High Quality Time-Scale Modification of Speech, Werner Verhelst and Marc Roelands , ICASSP 1993, pp. II-554-II-557).
The MATLAB exercise speeds-up or slows-down a speech or audio file by a factor of 'alpha', where 'alpha' is in the range of 0.33 (slow-down by a factor of 3-to-1) to 4.0 (speed-up by a factor of 4-to-1). The file '3.9 WSOLA.pdf' provides a User's Guide for this exercise.
