       aqualung [--output (jack|pulse|alsa|oss|sndio|win32)] [options] [file1 [file2 ...]]


       Aqualung  is  an  advanced  music  player  originally  targeted at the GNU/Linux operating
       system, today also running on FreeBSD, OpenBSD and Microsoft Windows. It plays audio  CDs,
       internet  radio  streams and podcasts as well as soundfiles in just about any audio format
       and has the feature of inserting no gaps between adjacent tracks. It  also  supports  high
       quality sample rate conversion between the file and the output device, when necessary.

       Audio  CDs  can  be  played  back  and ripped with on-the-fly conversion to WAV, FLAC, Ogg
       Vorbis or CBR/VBR MP3 (gapless via LAME). Seamless tagging of the created files is offered
       as part of the process. Internet radio stations streaming Ogg Vorbis or MP3 are supported.
       Subscribing to RSS and Atom  audio  podcasts  is  supported:  Aqualung  can  automatically
       download  and  add  new  files  to  the Music Store. Optional limits for the age, size and
       number of downloaded files can be set.

       Almost all sample-based, uncompressed formats (e.g. WAV, AIFF, AU etc.), as well as  files
       encoded  with  FLAC  (the  Free  Lossless  Audio Codec), Ogg Vorbis, Ogg Speex, MPEG Audio
       (including the infamous MP3 format), MOD audio formats (MOD, S3M, XM, IT, etc.),  Musepack
       and Monkey's Audio Codec are supported. Numerous formats and codecs are also supported via
       the FFmpeg project, including AC3, AAC, WMA, WavPack and  the  soundtrack  of  many  video
       formats.  There  is  also  a native (non-FFmpeg) WavPack decoder. The program can play the
       music through OSS, ALSA, sndio, PulseAudio, the JACK Audio Connection Kit, or  even  using
       the  Win32  Sound  API  (available  only  under  Cygwin or native Win32). Depending on the
       compile-time options, not all  file  formats  and  output  drivers  may  be  usable  in  a
       particular build. Type aqualung -v to get a list of all the compiled-in features.

       Aqualung  supports  the  LADSPA  1.1  plugin  standard. You can use any suitable plugin to
       enhance the music you are listening to.

       Other features of the program are: tabbed playlist, internally working volume and  balance
       controls  (not touching the soundcard mixer), multiple skin support, random seeking during
       playback, track repeat, list repeat and shuffle mode (besides normal playback).  In  track
       repeat mode the looping range is adjustable. Aqualung will come up in the same state as it
       was when you closed it, including playback modes, volume and balance  settings,  currently
       processing LADSPA plugins, window sizes, positions and visibility, and other miscellaneous
       options. Aqualung has the ability to display and edit Ogg Xiph comments, ID3v1, ID3v2  and
       APE tags, as well as FLAC picture frames found in files that support them. See the section
       about metadata support for full reference.

       The method of assembling the title string of a track is programmable (via a  user-provided
       Lua  function)  and  can include nearly any metadata item or audio file attribute. See the
       documentation of the Programmable title format file config setting for full reference.

       You can control any running instance of the program remotely from the command line (start,
       stop,  pause  etc.). Remote loading or enqueueing soundfiles as well as complete playlists
       is also supported.

       In addition to all this, Aqualung provides a so-called Music Store that  is  an  XML-based
       music  database,  capable  of  storing  various  metadata  about  music  on  your computer
       (including, but not limited to, the names of  artists,  and  the  titles  of  records  and
       tracks).  You  can  (and should) organize your music into trees of Artists/Records/Tracks,
       thereby making life easier than with the all-in-one Winamp/XMMS playlist.  Importing  file
       metadata (ID3v1, ID3v2 tags, Ogg Xiph comments, APE metadata) into the Music Store as well
       as getting track names from a CDDB/FreeDB database is supported. For  audio  CDs,  CD-Text
       retrieval is also implemented.

       Please  refer to the documentation available at the homepage for a detailed description of
       features, usage tips and troubleshooting issues. This manual page is  merely  an  abstract
       from  the  User's Manual, and documents only the command line interface of the program for
       quick reference.


       Normally you should be able to start Aqualung without any options. This  case  the  output
       device  will  be  selected  by  probing for a usable driver (in order of JACK, PulseAudio,
       ALSA, OSS) with default parameters.

       If no driver could be started with default parameters, or you want to explicitly choose  a
       suitable  output  configuration,  you have to tell the program which output device to use.
       This is possible with the -o (--output) option. There are specific optional parameters for
       all five output drivers. You can also specify which sample rate converter you want to use,
       or request a list of available converters. You may also control another  instance  of  the
       program remotely, or add files to the Playlist.

       General options

       -D, --disk-realtime
              Try  to  use  realtime (SCHED_FIFO) scheduling for disk thread, a background worker
              thread doing file decoding and sample rate conversion. Try this (and optionally -Y)
              if  you  experience short audio dropouts caused by other programs (e.g. web browser
              loading a complex page).

       -Y, --disk-priority <int>
              When running -D, set scheduler priority to <int> (defaults to 1).

       Options relevant to ALSA output

       -d, --device <name>
              Set the output device (defaults to 'default').

       -r, --rate <int>
              Set the output sample rate.

       -R, --realtime
              Try to use realtime (SCHED_FIFO) scheduling for ALSA output thread.

       -P, --priority <int>
              When running --realtime, set scheduler priority to <int> (default is 1 when  -R  is

       Options relevant to OSS output

       -d, --device <name>
              Set  the  output  device  (defaults  to  /dev/audio  on  OpenBSD, /dev/dsp on other

       -r, --rate <int>
              Set the output sample rate.

       -R, --realtime
              Try to use realtime (SCHED_FIFO) scheduling for OSS output thread.

       -P, --priority <int>
              When running --realtime, set scheduler priority to <int> (default is 1 when  -R  is

       Options relevant to JACK output

              Auto-connect  output  ports  to  given  JACK  ports (defaults to first two hardware
              playback ports).

       -c, --client <name>
              Set client name (needed if you want to run multiple instances of the program).

       Note that in the case when JACK output has been selected as part of the  automatic  output
       device detection, the -a option is implicitly applied.

       Options relevant to PulseAudio and sndio output

       -r, --rate <int>
              Set the output sample rate.

       -R, --realtime
              Try to use realtime (SCHED_FIFO) scheduling for sndio output thread.

       -P, --priority <int>
              When  running  --realtime, set scheduler priority to <int> (default is 1 when -R is

       Options relevant to Win32 output

       -r, --rate <int>
              Set the output sample rate.

       Options relevant to the Sample Rate Converter

       -s[<int>], --srctype[=<int>]
              Choose the SRC type, or print the list of available types if no number  given.  The
              default is SRC type 4 (Linear Interpolator).

       Options for remote cue control

       Note  that  remote  controlling  of instances is only possible if the instance you want to
       send a command to is running as the same user  as  you  are  when  you  issue  the  remote

       -N, --session <int>
              Specify  the  instance number to send the remote command to. Instances are numbered
              on a per user basis, starting with 0. Except  for  the  zero-th  instance  (started
              first), the instance number is displayed in the title bar of the main window (e.g.:
              `Aqualung.3'). If you don't use this option, the following options will control the
              zero-th  instance  by default, except for -L which defaults to the present instance
              (so as to be able to start playback immediately from the command line).

       -B, --back
              Jump to previous track.

       -F, --fwd
              Jump to next track.

       -L, --play
              Start playing.

       -U, --pause
              Pause playback, or resume if already paused.

       -T, --stop
              Stop playback.

       -V, --volume [m|M]|[=]<val>
              Adjust the volume. m/M means mute; if = is present, the  remote  instance's  volume
              control  will be set to the value specified, otherwise, the volume will be adjusted
              by the supplied (signed) value. The values are in dB units.

       -Q, --quit
              Terminate remote instance.

       Options for file loading

       You may specify filenames on the command line. These may be ordinary  soundfiles  playable
       by  Aqualung, directories, or playlist files you saved earlier. The program will decide if
       a file is a playlist, and add its contents accordingly. In addition to  Aqualung's  native
       (XML) playlist format, the program will load M3U and PLS playlists whenever possible.

       If  you  used  the  --session  option  (see above), the files will be sent to the Aqualung
       instance you specified. Otherwise a  new  instance  will  start  up  with  the  files  you
       specified.  Note  that  if  you  enabled the Save and restore the Playlist on exit/startup
       option  in  the  Settings  dialog,  the  files  you  specify  will  be  loaded  after  the
       automatically loaded ones.

       -E, --enqueue
              Enqueue  added  files  to  the  Playlist instead of loading them (which removes the
              previous contents of the Playlist). Use this if you want to keep the existing items
              in the Playlist.

       -t[<name>], --tab[=<name>]
              Specify target tab for file loading (either remotely using the --session option, or
              at startup). If --tab is used without the name parameter, the files will  be  added
              to  a  new (untitled) tab. If a name is supplied, Aqualung will check whether a tab
              with that name already exists. If so, the files will be loaded (or enqueued if  you
              used  -E)  to  that tab. If no such tab exists, one with that name will be created,
              and the content goes there.

       Options for changing state of Playlist/Music Store windows

       -l [yes|no], --show-pl=[yes|no]
              Show/hide Playlist window.

       -m [yes|no], --show-ms=[yes|no]
              Show/hide Music Store window.


       $ aqualung -s3 -o alsa -R -r 48000 -d plughw:0,0

       $ aqualung --srctype=1 --output oss --rate 96000

       $ aqualung -o jack --auto=system:playback_17,system:playback_18

       $ aqualung -o jack -a -E --tab="Led Zeppelin" `find ./ledzeppelin/ -name flac`


       Here is a list of files that Aqualung creates, reads and relies on.

              Directory containing user settings.

              GUI (skin, window size/position, etc.) and other settings.

              List of running plugins and all their settings.

              Automatically saved and restored playlist (if you enable this feature).

              Locally available skin <skin-name> (useful for skin development).

              System-wide skin directory.


       Aqualung obeys two environment variables concerning LADSPA plugins.

              Colon-separated list of paths to search for LADSPA plugin .so files.

              Colon-separated list of paths to RDF metadata files about these plugins.

       When any of these is not specified, the program will use sensible defaults and look in the
       obvious places.
