Freesound is a lib used for audio processing. Unfortunately, it doesn't work with python3. It lives in extlib, so we don't own the code. But, since the patch is pretty trivial, it was decided to merge it anyway and propose the fix to upstream. Which was done in https://github.com/MTG/freesound/pull/700 . Also, a bugreport was opened to use upstream version instead of our local, when it gets merged, ticket 5403.
