You can use the command line, as it is able to decode mpeg audio
files, but I'm not really sure about the library (I think not).

Nevertheless, I would recommend that you use another decoder, since
the decoder in lame has not been updated for quite some time if I
recall correctly.

I can say for sure that more than once I had an mp3 file that I wanted
to transcode to a lower bitrate mp3 file and the file had some
bad/corrupted frames. The decoding in lame just skipped everything
from the error untill the end of the file, which was not great.

On the other hand, you can use, say, mplayer (with the -ao pcm option)
or madplay to decode your mp3 files.


Hope this helps,

Do you still have those corrupted files? I mean, you could fix
our decoder to handle such cases, or maybe give someone else
the chance to do it.

Ciao Robert
