PROGRAM:
NAME
out123 - play raw PCM audio to an output device
SYNOPSIS
cat audio.raw | out123 [ options ]
DESCRIPTION
out123 reads raw PCM data (in host byte order) from standard input and plays it on the
audio device specified by given options.
OPTIONS
out123 options may be either the traditional POSIX one letter options, or the GNU style
long options. POSIX style options start with a single ``-'', while GNU long options start
with ``--''. Option arguments (if needed) follow separated by whitespace (not ``='').
Note that some options can be absent from your installation when disabled in the build
process.
-o module, --output module
Select audio output module. You can provide a comma-separated list to use the first
one that works.
--list-modules
List the available modules.
-a dev, --audiodevice dev
Specify the audio device to use. The default is system-dependent (usually
/dev/audio or /dev/dsp). Use this option if you have multiple audio devices and
the default is not what you want.
-s, --stdout
The audio samples are written to standard output, instead of playing them through
the audio device. The output format is the same as the input ... so in this mode,
mpg123 acts like the standard tool cat.
-O file, --outfile
Write raw output into a file (instead of simply redirecting standard output to a
file with the shell).
-w file, --wav
Write output as WAV file file , or standard output if - is used as file name. You
can also use --au and --cdr for AU and CDR format, respectively. Note that WAV/AU
writing to non-seekable files or redirected stdout needs some thought. The header
is written with the first actual data. The result of decoding nothing to WAV/AU is
a file consisting just of the header when it is seekable and really nothing when
not (not even a header). Correctly writing data with prophetic headers to stdout is
no easy business.
--au file
Write to file in SUN audio format. If - is used as the filename, the AU file is
written to stdout. See paragraph about WAV writing for header fun with non-seekable
streams.
--cdr file
Write to file as a CDR (CD-ROM audio, more correctly CDDA for Compact Disc Digital
Audio). If - is used as the filename, the CDR file is written to stdout.
-m, --mono
Set for single-channel audio (default is two channels, stereo).
--stereo
Select stereo output (2 channels, default).
-r rate, --rate rate
Set sample rate in Hz (default: 44100). If this does not match the actual input
sampling rate, you get changed pitch. Might be intentional;-)
-e enc, --encoding enc
Choose output sample encoding. Possible values look like f32 (32-bit floating
point), s32 (32-bit signed integer), u32 (32-bit unsigned integer) and the variants
with different numbers of bits (s24, u24, s16, u16, s8, u8) and also special
variants like ulaw and alaw 8-bit. See the output of out123's longhelp for
actually available encodings. Default is s16.
-o h, --headphones
Direct audio output to the headphone connector (some hardware only; AIX, HP, SUN).
-o s, --speaker
Direct audio output to the speaker (some hardware only; AIX, HP, SUN).
-o l, --lineout
Direct audio output to the line-out connector (some hardware only; AIX, HP, SUN).
-b size, --buffer size
Use an audio output buffer of size Kbytes. This is useful to bypass short periods
of heavy system activity, which would normally cause the audio output to be
interrupted. You should specify a buffer size of at least 1024 (i.e. 1 Mb, which
equals about 6 seconds of usual audio data) or more; less than about 300 does not
make much sense. The default is 0, which turns buffering off.
--preload fraction
Wait for the buffer to be filled to fraction before starting playback (fraction
between 0 and 1). You can tune this prebuffering to either get sound faster to your
ears or safer uninterrupted web radio. Default is 1 (wait for full buffer before
playback).
-t, --test
Test mode. The audio stream is read, but no output occurs.
-v, --verbose
Increase the verbosity level.
-q, --quiet
Quiet. Suppress diagnostic messages.
--aggressive
Tries to get higher priority
-T, --realtime
Tries to gain realtime priority. This option usually requires root privileges to
have any effect.
-?, --help
Shows short usage instructions.
--longhelp
Shows long usage instructions.
--version
Print the version string.
