AdPlay/UNIX 1.8.1                                 May 24, 2020                                         ADPLAY(1)

       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.

adplay returns 0 on successful operation. 1 is returned otherwise.

       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.

   Outputselection:-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.

   OSSdriver(oss)specific:-d--device=FILE
              Set sound output device file to FILE. This is /dev/dsp by default.

   Diskwriter(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!

   EsounDoutput(esound)specific:-d--device=URL
              Connect  to  "hostname:port"  combination in URL. Example: "myhost.sound.net:1234". The default is
              "localhost:16001".

   ALSAdriver(alsa)specific:-d--device=DEVICE
              Set sound output device to DEVICE. This is plughw:0,0 by default.

   Playbackquality:-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 if AdPlug <= 2.1.)

       --surround
              Use only stereo samples for playback, but generate them from two mono OPL2 chips.  One  OPL2  chip
              is  very  slightly  transposed  to  produce  a pleasant harmonic/surround sound effect (default if
              AdPlug >= 2.2.)

       -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.

   Informativeoutput:-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 default subsong of the file. 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.

       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--OpenSoundSystem(OSS)driver
       This output method is available on most Linux and other UNIX systems.

   null--Totalsilence
       Discards anything sent to it. It can be useful for testing purposes.

   disk--Diskwriter
       Writes its output to a file in Microsoft RIFF WAVE format.

   esound--EsounDoutput
       Creates a socket connection to an EsounD server and streams the audio to it.

   qsa--QNXSoundArchitecture(QSA)driver
       Uses the QNX system's standard output method.

   sdl--SimpleDirectmediaLayer(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--AdvancedLinuxSoundArchitecture(ALSA)driver
       Uses the standard output method on newer Linux systems.

   ao--libaodriver
       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.
