WAV audio format: MPEG3 to PCM

How can you convert wav files with MPeg layer 3 (MPeg3) audio format to PCM?

From stackoverflow

• You could use FFMPEG called from the command-line, like so:

  ffmpeg -i source.wav -f wav -acodec pcm dest.wav
  

  NOTE: Untested

  Also, Windows binaries are available (I had some from another place as well) here.

• LibMAD could be what you are looking for.

• If finding a windows binary of ffmpeg is too much work you can install foobar2k and do it from there
