I want to play music in the terminal with sox.

# install sox/lame
sudo apt-get install sox
sudo apt-get install lame

# play music
play music.mp3
# play FAIL formats: no handler for file extension `mp3'

# mp3 -> wav
lame --decode music.mp3 music.wav

# play music
play music.wav

~ $ cat /etc/lsb-release 

~ $ sox --version
sox: SoX v14.3.2

The size of music.wav is +10 times larger than music.mp3.
I don't want to convert all *.mp3 to *.wav.
Is it possible to add mp3-handler to sox?

  • what linux distro are you on... and what version of the distro and sox are you running... also running sox -h reports codecs supported by the program... please check if mp3 is supported therein... May 6, 2012 at 7:59

    instead of the present accepted answer (lame/pipe), the correct/simplest answer is install libsox-fmt-all superuser.com/a/421168/73961

lame --decode music.mp3 - | play -

Won't leave any trace.

    The question was about a sox handler. This is definitely not sox :)

    @Elektordi The play command is SoX. It's basically sox -d. Like ffmpeg vs. ffplay.

Install libsox-fmt-mp3:

sudo apt-get install libsox-fmt-mp3

    I found I also needed to upgrade sox after that; so it doesn't hurt to add "sox" to the above command. Sep 12, 2012 at 5:44
  • This does not work for me. Even after aptitude reinstall sox I still get a SoX was compiled without MP3 encoding support when I try to run sox afterwards. (Though admittedly I'm still running Lucid, this might work better on a more modern Ubuntu.)

    @kev, you should select this as the accepted answer. Also, there is a libsox-fmt-all package that installs the mp3 format, as well as all other available formats.

    +1, this should be the accepted answer because it allows for other things beyond playing as well, for example conversion (e.g. sox input.wav output.mp3 won't work without this package)
