well
I've found out what causes the problem. It's this:
AUDIO: 8000 Hz
I've tried playing the file with audacity, and it woks fine. If I reencode it using
Project Rate (Hz) 44100
which I see is the rate of all my mp3 files, then it sounds correct.
Now I have to find out how to do this from the command lline
Any one is patient enough to tell me what this "rate" consists of?
