Problems with pvoc anal 1

[andbe]

Hi,
I have tried to do a pv analysis of a mono sound file in wav format (24-bit, 48kHz) like this:
pvoc anal 1 test.wav test.ana
but I keep getting
ERROR: Invalid data
ERROR: Cannot open output file test
I am on OSX 10.9.5 working from terminal.
Any ideas what's wrong?
Best,
Andreas

At the terminal, enter "export CDP_SOUND_EXT=wav", then try your command again.  If it works, just add this export line to your .bash_profile (sans quotes) and this shouldn't crop up again.

That did it! Thanks a lot
