MPG321(1)		    General Commands Manual		     MPG321(1)

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

SYNOPSIS
       mpg321 [options]	file(s)	| URL(s) | -

DESCRIPTION
       mpg321  is a free command-line mp3 player, which	uses the mad audio de-
       coding library. mpg321 is written to be a drop-in replacement  for  the
       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).

       mpg321 differs from mpg123     in several ways. First and foremost,  it
       is  fully  Free,	under the GNU General Public License. Secondly,	it al-
       lows run-time switching of output devices (via the -o switch).  (mpg321
       also  allows  configuring  a default output device at compile-time, but
       run-time	switching is always allowed).

OPTIONS
       -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, de-
		 pending on the	output device you've chosen  (via  -o  device-
		 type).	  By  default this is the native sound device.	Gener-
		 ally 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; de-
		 faults	to localhost.

		 For -o	alsa, specify card:device; defaults to 0:0.

       -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	 file-
		 names	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.	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.

       -t, --test
		 Test mode; do no output at all.

       -q, --quiet
		 Quiet	mode;  suppress	 output	of mpg123 boilerplate and file
		 and song name.

       -R	 "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.)

       --stereo	 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
		 Aggressive mode; try to get higher priority  on  the  system.
		 Needs root permissions.

       --skip-printing-frames=N
		 Skip N	frames between printing	a frame	status update, in both
		 Remote	Control	(-R) and verbose (-v) mode. Can	help CPU util-
		 isation  on  slower  machines.	This is	an mpg321-specific op-
		 tion.

       --help, --longhelp
		 Show summary of options.

       -V, --version
		 Show version of program.
