reads Ogg Vorbis audio files and decodes them to the devices specified
on the command line. By default,
writes to the standard sound device, but output can be sent to any
number of devices. Files can be read from the file system, or URLs
can be streamed via HTTP. If a directory is given, all of the files in
it or its subdirectories will be played.
Use an output audio buffer of approximately 'n' kilobytes.
-@ playlist, --list playlist
Play all of the files named in the file 'playlist'. The playlist should have
one filename, directory name, or URL per line. Blank lines are permitted.
Directories will be treated in the same way as on the command line.
-b n, --buffer n
Use an input buffer of approximately 'n' kilobytes. HTTP-only option.
-p n, --prebuffer n
Prebuffer 'n' percent of the input buffer. Playback won't begin until
this prebuffer is complete. HTTP-only option.
-d device, --device device
Specify output device. See
section for a list of devices. Any number of devices may be specified.
-f filename, --file filename
Specify output file for file devices. The filename "-" writes to standard
out. If the file already exists,
will overwrite it.
Show command help.
-k n, --skip n
Skip the first 'n' seconds. 'n' may also be in minutes:seconds or
-K n, --end n
Stops playing 'n' seconds from the start of the stream. 'n' may also have the
same format as used in the
-o option[:value], --device-option option[:value]
Sets the option
for the preceding device. See
for a list of valid options for each device.
Quiet mode. No messages are displayed.
Display version information.
-x n, --nth
Play every 'n'th decoded block. Has the effect of playing audio at 'n' times
faster than normal speed.
-y n, --ntimes
Repeat every played block 'n' times. Has the effect of playing audio 'n'
times slower than normal speed. May be with -x for interesting fractional
Repeat playlist indefinitely.
Play files in pseudo-random order.
Play files in pseudo-random order forever.
supports a variety of audio output devices through libao. Only those
devices supported by the target platform will be available. The
option may only be used with devices that write to files.
Options supported by all devices:
Turn on debugging output [if any] for a chosen driver.
Force a specific output channel ordering for a given device.
is a comma
seperated list of AO style channel names, eg, L,R,C,LFE,BL,BR,SL,SR.
Turn on verbose output for a chosen driver. the -v option will also set the
driver verbose option.
Force chosen driver to be completely silent. Even errors will not produce any
output. -q will also set the driver quiet option.
AIX live output driver. Options:
Set AIX output device to
Advanced Linux Sound Architecture live output driver. Options:
Override the default hardware buffer size (in milliseconds).
ALSA device label to use. Examples include "hw:0" for the first soundcard
and "hw:1" for the second. The alsa driver normally chooses one of
automatically depending on number of output channels. For more information,
Override the default hardware period size (in microseconds).
Override the default hardware period size (in microseconds).
is set to "yes" or "no" to override the compiled-in default to use or not use
mmap device access. In the past, some buggy alsa drivers have behaved better when
not using mmap access at the penalty of slightly higher CPU usage.
aRts Sound Daemon live output driver. Options:
is set to "yes" or "no" to allow opening the aRts playback device for multiply
concurrent playback. Although the driver works properly in multi mode, it is
known to occasionally crash the aRts server itself. Default behavior is "no".
Sun audio file output. Writes the audio samples in AU format. The AU
format supports writing to unseekable files like standard out. In
such circumstances, the AU header will specify the sample format, but
not the length of the recording.
Enlightened Sound Daemon live output. Options:
specifies the hostname where esd is running. This can include a port number
after a colon, as in "whizbang.com:555". (Default = localhost)
IRIX live output audio driver.
MacOS X 'AUHAL' live output driver. This driver supports MacOS X
10.5 and later (10.4 and earlier uses an earlier, incompatable
Set the hardware buffer size to the equivalent of
Network Audio Server live output driver. Options:
Set size of audio buffer on server in bytes.
Set location of NAS server; See nas(1) for format.
Null driver. All audio data is discarded. (Note: Audio data is not
!) You could use this driver to test raw decoding speed without
Open Sound System driver for Linux and FreeBSD, versions 2, 3 and 4. Options:
DSP device for soundcard. Defaults to
Pulseaudio live audio sound driver. Options:
Specifies location of remote or alternate Pulseaudio server.
Specifies a non-default Pulseaudio sink for audio stream.
Raw file output. Writes raw audio samples to a file. Options:
Chooses big endian ("big"), little endian ("little"), or native ("native") byte order.
Default is native order.
Roar Audio Daemon live output driver. Options:
Specifies location of remote Roar server to use.
OpenBSD SNDIO live output driver. Options:
Specifies audio device to use for playback.
Sun Audio live output driver for NetBSD, OpenBSD, and Solaris. Options:
Audio device for soundcard. Defaults to
WAV file output. Writes the sound data to disk in uncompressed form.
If multiple files are played, all of them will be concatenated into
the same WAV file. WAV files cannot be written to unseekable files,
such as standard out. Use the AU format instead.
Windows MultiMedia live output driver for Win98 and later. Options:
Selects audio device to use for playback by device name.
Selects audio device to use for playback by device id (card number).
command line is fairly flexible, perhaps confusingly so. Here are
some sample command lines and an explanation of what they do.
Play on the default soundcard:
Play all of the files in the directory ~/music and its subdirectories.
Play a file using the OSS driver:
ogg123 -d oss test.ogg
Pass the "dsp" option to the OSS driver:
ogg123 -d oss -o dsp:/dev/mydsp
Use the ESD driver
ogg123 -d esd test.ogg
Use the WAV driver with the output file, "test.wav":
ogg123 -d wav -f test.wav test.ogg
Listen to a file while you write it to a WAV file:
ogg123 -d oss -d wav -f test.wav test.ogg
Note that options apply to the device declared to the left:
Create an echo effect with esd and a slow computer:
ogg123 -d esd -d esd test.ogg
You can abort
at any time by pressing Ctrl-C. If you are playing multiple
files, this will stop the current file and begin playing the
next one. If you want to abort playing immediately instead
of skipping to the next file, press Ctrl-C within the first
second of the playback of a new file.
Note that the result of pressing Ctrl-C might not be audible
immediately, due to audio data buffering in the audio device.
This delay is system dependent, but it is usually not more
than one or two seconds.
Can be used to set the default output device for all libao programs.
Per-user config file to override the system wide output device settings.
Piped WAV files may cause strange behavior in other programs. This is
because WAV files store the data length in the header. However, the
output driver does not know the length when it writes the header, and
there is no value that means "length unknown". Use the raw or au
output driver if you need to use ogg123 in a pipe.
