Are there any signal processing libraries that implement TD-PSOLA? For such a popular and old algorithm, I've had surprisingly little luck finding implementations. I've got it working in MATLAB, but am curious if any other languages have libraries containing it (python?). I've googled extensively to no avail.
When I'm looking for source code, I generally search the open repositories rather than Google.

Try this one in C++.

However, there don't seem to be many on github, and sourceforge has nothing of interest.
