LinuxQuestions.org - decoding mp3 to pcm format !!

Code:

shell$ mpg123 -s some_music.mp3 >some_music.pcm

From the mpg321 man page:

mpg321 -- Free clone of mpg123, a command-line mp3 player

[..snip..]

-s, --stdout
Use standard output instead of an audio device for output.
Output is in 16-bit PCM, little-endian.

-w N, --wav N
Write to wav file N instead of using the audio device. This
option will be preferred if --cdr or --au are specified too.
Specifying '-' for N will cause the file to be written to
standard output.

--cdr N Write to cdr file N instead of using the audio device. Speci-
fying '-' for N will cause the file to be written to standard
output.

--au N Write to au file N instead of using the audio device. Speci-
fying '-' for N will cause the file to be written to standard
output.

See the "sox" program for some other/more conversions.
