Hi Paul,

I'm trying to run this on MacOS High Sierra 10.13.6. Python 2.7.10.

I've tried a variety of wav files from sample packs and so forth as a test, and have gotten nothing but "Error loading wav..."; I added a bit of code to get more information. Seems I get a ValueError exception, which contains the following: "string size must be a multiple of element size"

It is triggered from this line:

wavedata=scipy.io.wavfile.read(filename)

I can dig further but was hoping you might just have an idea of what might be wrong here.

All I did was clone, copy a wav to the working directory as a.wav, then run:

./paulstretch_stereo.py a.wav b.wav

Full output:
