mpg321 — Simple and lightweight command line MP3 player
mpg321 [options] file(s) | URL(s) | -
mpg321 is a free command-line mp3 player, which uses the mad audio decoding library. mpg321 was written to be a drop-in replacement for the (by-then) non-free mpg123 player. Some functions remain unimplemented, but mpg321 should function as a basic drop-in replacement for mpg123 front-ends such as gqmpeg, and those programs which use mpg123 to decode mp3 files (like gtoaster, and other CD-recording software).
- -o devicetype
- Set the output device type to devicetype. devicetype can be one of:
- oss - the Linux Open Sound System;
- sun - the Sun audio system;
- alsa - the Advanced Linux Sound Architecture;
- alsa09 - the Advanced Linux Sound Architecture, version 0.9;
- esd - the Enlightened Sound Daemon;
- arts - the analog real-time synthesiser
- See -a device, below.
- -a device, --audiodevice device
- Use device for audio-out instead of the default device, depending on the output device you've chosen (via -o devicetype). By default this is the native sound device. Generally this is the device for devicetype (or the default system device) to use for output (i.e. /dev/sound/dsp1).
- This option has no effect with -o arts.
- For -o esd, specify the host on which esd is running; defaults to localhost.
- For -o alsa, specify audio device using the hw:x,y syntax, where x and y are numbers, default is hw:0,0. For example, if there is only one device installed, in most cases, the device should be named hw:0,0. When there is only one device, the device should always have the same name and numbers.
- -g N, --gain N
- Set gain (volume) to N (1-100).
- -k N, --skip N
- Skip N frames into the file being played.
- -n N, --frames N
- Decode only the first N frames of the stream. By default, the entire stream is decoded.
- -@ list, --list list
- Use the file list for a playlist. The list should be in a format of filenames followed by a line feed. Multiple -@ or --list specifiers will be ignored; only the last -@ or --list option will be used. The playlist is concatenated with filenames specified on the command-line to produce one master playlist. A filename of '-' will cause standard input to be read as a playlist.
- -z, --shuffle
- Shuffle playlists and files specified on the command-line. Produces a randomly-sorted playlist which is then played through once.
- -Z, --random
- Randomise playlists and files specified on the command-line. Files are played through, choosing at random; this means that random files will be played for as long as mpg321 is running.
- -v, --verbose
- Be more verbose. Show current byte, bytes remaining, time, and time remaining, as well as more information about the mp3 file.
- -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. Specifying '-' 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. Specifying '-' for N will cause the file to be written to standard output.
- -t, --test
- Test mode; do no output at all.
- -q, --quiet
- Quiet mode; suppress output of mpg123 boilerplate and file and song name.
- Read recursively the given directories. Allows you to define only the directory or directories and then mpg321 recursively plays all the songs.
- Turn on FFT analysis on PCM data. Remote mode only
- Report song to AudioScrobbler (last.fm).
- Set xterm title setting
- Number of decoded frames for the output buffer.
- Enable Basic Keys.
- "Remote control" mode. Useful for front-ends. Allows seeking and pausing of mp3 files. See README.remote (in /usr/share/doc/mpg321 on Debian and some other systems.)
- -3, --restart
- Restart "remote shell". Used only when in "Remote control" mode.
- Force stereo output: duplicates mono stream on second output channel. Useful for output for devices that don't understand mono, such as some CD players.
- Aggressive mode; try to get higher priority on the system. Needs root permissions.
- Skip N frames between printing a frame status update, in both Remote Control (-R) and verbose (-v) mode. Can help CPU utilisation on slower machines. This is an mpg321-specific option.
- -l N, --loop N
- Loop song or playlist N times.If N is 0 means infinite times.
- --help, --longhelp
- Show summary of options.
- -V, --version
- Show version of program.
