[LAU] paustretch_stereo.py and 24bit files?

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 Here's the error: paulstretch_stereo.py -s 4 -w 0.22097 24bitInfile.wav outfile.wav Paul's Extreme Sound Stretch (Paulstretch) - Python version 20110222 by Nasca Octavian PAUL, Targu Mures, Romania stretch amount = 4.0 window size = 0.22097 seconds /usr/lib/python2.7/dist-packages/scipy/io/wavfile.py:147: WavFileWarning: Chunk (non-data) not understood, skipping it.
