Another sound file cannot be used #1

This sound file, although having about the same length and similar structure, cannot be opened. I'm not sure what's the reason. (Audacity doesn't support other bitrates, if that's the matter.) https://dl.dropboxusercontent.com/u/6721960/2014/throat.wav.zip

If there is something my little program hasn't, it's flexibility ! I believe the problem is that your wav file has two channels. If you open the file in Audacity and remove one channel (make it mono) it should work.

That did work, thanks! Cople of flies to try :) https://dl.dropboxusercontent.com/u/6721960/2014/throat-singing.zip
