Re: MP3 encoding of wav files from Olympus voice recorder

My Olympus Voice Recorder VN-960PC generates wav files, and I wonder
why I cannot mp3 encode them using LAME. If I try to do so, I get mp3
files that are inaudible, I mean, I can hear nothing else than a
background noise like compressed air leaking out of a cut tire.

Take one of these .wav files and run file on it. Like so:

clairissa:/usr/share/sounds$ file k3b_error1.wav
k3b_error1.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 8
bit, mono 8000 Hz

....and reproduce the data for us. Also give the exact lame command
you're using. Finally, play one of these .wav files using play or
whatever, and make sure it plays properly.

I can successfully encode *.wav files coming from anywhere [else], but
not those that come out from my voice recorder. Could anyone explain
me what the problem could be and what to do about it?

..wav files do not necessarily have to contain PCM data. They usually
do, but not always. They could contain audio that's compressed in some
way, or they could have a strange sampling rate, or they could be mono
where lame is expecting stereo. The output of the file command will
tell you what the file really is.

How should I set lame parameters for those particular wav files?

Check what the file really is, and check the man page for lame to set
things up properly. HTH,
