Further:
Z=. 2 wavfile '/home/jph/j903/addons/media/wav/test1.wav'
$Z
22108
But ...
Z=. 2 wavfile '/home/jph/Desktop/Aomago/Ao1.wav'
$Z
0
So 2 wavefile 'name.wav' reads Oleg's test data but not mine.

I just tested--the wavfile and wavdata verbs, at least, seem to work
without issue on linux. I expect it is only playback that is
windows-specific. Are you specifically looking to perform playback,
or only analysis?
I tried wavdata on a 44mb wav file, and it produced a result without
issue, so I do not think there are size limitations. It's possible
there are nonstandard chunks in the file which are messing the parser
up. Try running e.g. 'ffmpeg -i x.wav y.wav', if your file is x.wav,
and see if you have better luck processing y.wav.

I have been investigating some data in the form of .wav files taken
with a compact digital audio recorder. In the addons I found the
tools by Oleg K under media/wav. One limitation is that they seem to
work only under windows. I normally work under Ubuntu linux or even
Mac OS. I do have a PC with j903 installed, and the media/wav
examples work on that machine. Has anyone tried to extend this addon
to other operating systems, or are there significant obstacles with
other OS's?
I also find that in trying to analyze my own .wav files which are
fairly large (~14 Mb), while wavinfo works fine, wavdata fails with
an index error or spelling error. I wonder if there are size
limitations that are the problem, or just some mistake of mine.
Anyway, if there are resources or further information on .wav files
under J (I've not searched extensively) I'd be interested to learn
about them.
Thanks, Patrick
