I would like to convert wav files to mp3 using the lame encoder (lame.exe). The wav files are recorded along the following specifications:

Bit Rate: 64kbps
Audio sample size: 8 bit
Channels: 1 (mono)
Audio sample rate: 8 kHz
Audio format: CCITT A-Law

If I try to convert such a wav file using lame.exe, I get the following error message:

Unsupported data format: 0x0006

Could anyone provide me with a command line string using lame.exe that will enable me to convert these kind of wav files to mp3?

If you try the version that's compiled with 'libsndfile', that should do the trick. The standard .exe doesn't know how to decode A-law files.

Thanks a lot john33. I downloaded "LAME 3.98.2 using libsndfile 1.0.18pre22a" from rarewares.org. That version converted the .wav-file to .mp3, and I didn't have to add any command line parameters.
