MP3 to WAV Conversion on Linux
MP3 to WAV conversion is remarkably simple:
mpg123 -w out.wav in.mp3
For the purpose of writing an audio CD, a sample rate of 44100 Hz and stereo output are essential:
mpg123 --stereo -r 44100 -w out.wav in.mp3
And then to write the WAV files to a CD:
cdrecord -audio -pad *.wav
