Re: [SoX-users] mp3 support in bin for win32 or ubuntu?

[Chris B. <ch...@cn...>]

MP3 is encumbered with patents and we can not distributed binaries.

Your best bet is to download an command line MP3 player; such as
mpg123, mpg321, or madplay.  I think you'll have a higher chance
of finding these binaries or at the least they are easier to
compile yourself.

Then you can use this in conjunction with SoX.  
Something along the lines of:

madplay --output=wav:- filename.mp3 | sox -t wav - outputfile.wav

Exact commandline will vary between programs.
