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.
