NAME
adplay - AdPlay/UNIX console-based OPL2 audio player
SYNOPSIS
adplay [OPTION]... FILE...
DESCRIPTION
AdPlay/UNIX is AdPlug’s UNIX console-based frontend. It tries to play
back all given FILEs, using one of many available output mechanisms.
AdPlay/UNIX plays endlessly, if only one file is given. With multiple
files, it plays them in a sequence and exits after the last file. The
same can also be accomplished with only one file, by using the -o
option. When using the disk writer, -o is implied.
EXIT STATUS
adplay returns 0 on successful operation. 1 is returned otherwise.
OUTPUT MECHANISMS
AdPlay/UNIX can play back using many different output mechanisms, which
can be selected with the -O argument. The availability of a method
depends on compile-time settings. Available methods are printed out
after the help text, displayed with --help.
Next is a brief description of all output mechanisms, following their
abbreviations:
oss -- Open Sound System (OSS) driver
This output method is available on most Linux and other UNIX systems.
null -- Total silence
Discards anything sent to it. It can be useful for testing purposes.
disk -- Disk writer
Writes its output to a file in Microsoft RIFF WAVE format.
esound -- EsounD output
Creates a socket connection to an EsounD server and streams the audio
to it.
qsa -- QNX Sound Architecture (QSA) driver
Uses the QNX system’s standard output method.
sdl -- Simple Directmedia Layer (SDL) driver
Uses the SDL library for sound output. The library has a broader
platform support than any of the other output methods. Thus, it could
be useful on some exotic systems.
alsa -- Advanced Linux Sound Architecture (ALSA) driver
Uses the standard output method on newer Linux systems.
ao -- libao driver
Libao is a cross-platform audio library with very broad platform
support. Might be useful on systems, where SDL is not available, and
generally to do tricky things.
OPTIONS
The order of the option commandline parameters is not important, except
for the -d option, which always has to be specified after an -O option.
Output selection:
-O, --output=OUTPUT
Specify output mechanism. Available mechanisms depend on
compilation settings and are printed on --help output. A
reasonable default is automatically selected, based on the
availability of the output mechanisms.
OSS driver (oss) specific:
-d --device=FILE
Set sound output device file to FILE. This is /dev/dsp by
default.
Disk writer (disk) specific:
-d --device=FILE
Write sound data to FILE. The data is written in Microsoft RIFF
WAVE format (little-endian). You can specify a single ’-’ to
write to stdout instead. This option has no default and must be
specified when the disk writer is to be used!
EsounD output (esound) specific:
-d --device=URL
Connect to "hostname:port" combination in URL. Example:
"myhost.sound.net:1234". The default is "localhost:16001".
ALSA driver (alsa) specific:
-d --device=DEVICE
Set sound output device to DEVICE. This is plughw:0,0 by
default.
Playback quality:
-8, --8bit
Use only 8-bit samples for playback.
--16bit
Use only 16-bit samples for playback (default).
-f, --freq=FREQ
Set playback frequency to FREQ, in Hz. This is 44100Hz by
default.
--stereo
Use only stereo samples for playback. The sound stream is just
doubled, no further audio processing is done. This option is
pretty useless unless you have very obscure audio hardware that
only accepts stereo streams. AdPlug only generates mono streams
because the OPL2 only generates mono sound.
--mono Use only mono samples for playback (default).
-b --buffer=SIZE
Set sound buffer size to SIZE samples. If you notice sound
skipping with the default setting, try a greater buffer size.
Note that this is measured in samples, not bytes! This is 2048
samples by default. Only the OSS, SDL, ALSA and libao output
drivers support this option.
Informative output:
-i --instruments
Display instrument names (if available).
-r --realtime
Display realtime playback information, while playing. This will
display a one-line status bar, containing essential playback
information.
-m --message
Display the song message (if available).
Playback:
-s --subsong=N Play subsong number N, instead of the first
subsong. Only useful for file formats that support multiple
subsongs.
-o --once
Play just once, don’t loop. This will exit adplay after the song
ended. This is the default when multiple FILEs are given.
Miscellaneous:
-D, --database=FILE
Additionally use database file FILE. This option may be
specified multiple times. Each database file is additionally
merged with the others, creating one large database on the fly.
-q, --quiet
Be more quiet.
-v, --verbose
Be more verbose.
-h, --help
Show summary of options.
-V, --version
Show version of program.
