For start, I recomand to use "paulstretch_stereo.py".
The "paulstretch_mono.py" is a very simple test implementation of the Paulstretch algorithm.
The "paulstretch_newmethod.py" is a extended/slower Paulstretch algorithm which has onset detection.
"paulstretch_steps.png" describes the steps of Paulstretch algorithm graphically.
The Paulstretch algorithm is released under Public Domain.
