NAME

       alsaplayer - plays various sound files

SYNOPSIS

       alsaplayer [options] [ filename ...]

DESCRIPTION

       This  manual  page documents briefly the alsaplayer command.  This manual page was written
       for the Debian GNU/Linux distribution because the original program does not have a  manual
       page.

       alsaplayer is a generic music player that can play back a large amount of file formats.

       If  files are specified on the command line, these files are played.  Otherwise alsaplayer
       plays its playlist from its last run, if any.

FILENAME

       Play the specified file(s). Can be a file or an URL.

       CD.cdda
              Special filename. Play a  CD.  /dev/cdrom  will  be  used  by  default.  Otherwise,
              AlsaPlayer   will   use   the   device  specified  in  your  config  file  (usually
              ~/.alsaplayer/config).

OPTIONS

       These programs follow the usual GNU command line syntax, with long options  starting  with
       two dashes (`-').  A summary of options is included below.

       -c, --config <file>
              Use the given config file for this session.

       -h, --help
              Print this help message.

       -i, --interface <interface>
              Use the specified interface instead of the default one.

       -I, --script <file>
              Specify the script to pass to the interface plugin.

       -l, --startvolume <vol>
              Start with this volume [default=1.0].

       -p, --path <path>
              Set the path alsaplayer looks for add-ons.

       -q, --quiet
              Quiet operation, no output.

       -s, --session-name name
              Name this session "name"

       -v, --version
              Print version of this program.

       --verbose
              Be verbose about the output.

       --nosave
              Do not save playlist content at exit.

   Player control:
       -n, --session #
              Select session # [default=0]

       -e, --enqueue file(s)
              Enqueue file(s) in a running alsaplayer.

       -E, --replace file(s)
              Clears and queues file(s) in a running alsaplayer.

       --status
              Get some information about the session.

       --volume #
              Set software volume [0.0-1.0].

       --start
              Start playing.

       --stop Stop playing.

       --pause
              Pause/unpause playing.

       --prev Jump to the previous track.

       --next Jump to the next track.

       --seek <second>
              Jump to the specified second in the current track.

       --relative <second>
              Jump <second> seconds from current position.

       --speed <value>
              Set  the  playback  speed  with  -10  <= <value> <= 10.  1.0 = normal speed, -1.0 =
              normal speed backwards.  Be aware that alsaplayer respect your LOCALE. That implies
              that  the  decimal  point  will vary accordingly. I.e., with french LOCALE, a valid
              speed value is 1,5 and not 1.5.

       --jump #
              Jump to the specified playlist track.

       --clear
              Clear the whole playlist

       --quit Quit the session.

   Sound driver options:
       -d, --device string
              Select the specific device for the output plugin.  For the ALSA plugin, the default
              is      "default".      For     the     JACK     plugin,     the     default     is
              "alsa_pcm:playback_1,alsa_pcm:playback_2".

       -f, --fragsize #
              Set fragment size in bytes [default=4096].

       -F, --frequency #
              Set the output frequency [default=44100].

       -g, --fragcount #
              Fragment count [default=8].

       -r, --realtime
              Enable realtime scheduling.  To use this as a normal user, alsaplayer must be  SUID
              root.

       -o, --output [alsa|esound|jack|nas|null|oss|sgi|sparc]
              Use the specified output driver.

   Experimental options:
       -S,--loopsong
              Loop the file.

       -P,--looplist
              Loop the playlist.

       -x,--crossfade
              Crossfade playlist entries.

JACK OUTPUT PLUGIN

       For  use  with  JACK,  -F <sample_rate> is mandatory for best results. The value of sample
       rate must be the same as the one used by jackd.

       If you forget the -F parameter, the sound can be very bad. The only remedy at that time is
       to restart both jackd and AlsaPlayer.

DAEMON INTERFACE

       With  the daemon interface, it is mandatory to add the -s option.  You must process in two
       steps to get sound with it. First launch the daemon:

       alsaplayer -i daemon -s <name>

       and then add some song:

       alsaplayer -e <some.song>

GTK+ INTERFACE

       The gtk+ interface provide some basic keyboard controls:

       v      Stop

       x      Play

       c      Pause

       b      Next Song

       z      Previous Song

       g      Seek Forward

       a      Seek Backward

       f      Forward Play

       s      Reverse Play

       t      Speed Up one musical semitone. (handy for changing the key the song is played  back
              in)

       q      Speed Down one musical semitone.

       h      Speed  Up  one comma. (handy to tune the song instead of the guitar when playing at
              the same time as listening)

       i      Speed Down one comma.

       r      Volume Up

       w      Volume Down

       l      Loop
