[LAU] paustretch_stereo.py and 24bit files?

[Peter P.]

Dear Paul,

thank you for the command line version of paulstretch! Iterestingly
when I load a 24bit wav file into the GUI version, it gets accepted
(at what point in the processing is its wordlength reduce by the
way?). When I try to run paulstretch_stereo.py with any non-16bit wav
file It refuses to work, giving the error below.
Is there a reason the GUI version accepts these files and the python
version does not? I need to batch-process a large number of files, so
the command-line version would come in super handy. I can always
reduce the wordlength of the files myself before the processing, I
just thought i'd ask :)
Thank you again for these wonderful tools!
best, Peter
