       fische - standalone sound visualisation


       fische [options]


       -D --driver driver

              Use  the  specified audio input driver. Presently alsa and pulse
              are supported. Autodetected by default.

       -d --device device

              device names the alsa pcm capture device to get the  sound  data
              from. Does nothing when PulseAudio is used. On most systems, the
              default will do just fine.

       -g --geometry XxY

              X and Y specify the width and height of the animation.  Defaults
              to 800x400.

       -v --virtual XxY

              X  and Y specify the width and height of the application window.
              Use this to prevent your  computer  from  trying  to  switch  to
              non-existent fullscreen resolutions.

       -f --fullscreen

              Start fische in fullscreen mode.

       -s --fps fps

              fps  specifies the target frames per second. The default, 30, is
              what fische is designed for

       -1 --single

              Use only one CPU, even if there are more available

       -p --predictive

              Use predictive beat detection (experimental)


              Exit  when  a  mouse  button  is  clicked  (useful   mainly   on

       -n --nowrite

              Do not update the configuration file with the last known working

       -h --help

              Display a basic help message.


       At runtime, press P to pause, F to toggle fullscreen mode  and  ESC  to
       quit.  R  toggles  predictive  beat detection, which is experimental at
       this stage. With the --exit-on-mouseevent  flag,  fische  does  exactly


       If you get an error like "X Error of failed request: BadValue..."

              Try  to  start fische with the -v or --virtual flags and set X/Y
              to values that correspond to a fullscreen  resolution  that  you
              know exists. For example: fische -g 1400x700 -v 1400x1050

       If fische starts, but wont react to sound

              First  of  all,  try a different input driver. If you are lucky,
              this already solves your problem.

              If not, you now have to choose which driver you  would  like  to
              get working:

              pulse:  Fische  opens the default source as set with pavucontrol
              or similar tools. For example, if you would  like  to  visualize
              "what’s  playing", set the corresponding "monitor of output XYZ"
              device as default.

              alsa: You might be using the  wrong  ALSA  device.  By  default,
              fische  tries  to  open  the  "default"  device.  It  should  be
              correctly configured on most systems, but with  some  soundcards
              you   need  complex  ALSA  configuration  to  achieve  recording
              capabilities - look into the ALSA  documentation.  For  example,
              soundcards  with  ICE1712 chips record internally produced sound
              on channels 10 and 11 instead of 0 and 1.

              alsa: Recording might not be enabled. Check with "alsamixer"  or
              an  other  mixer  application.  If  you  are trying to visualize
              sounds produced by an audio player, you must enable recording of
              what’s  called  "PCM"  on most cards. For external input, record
              "Line In", and so on...

              alsa: Your sound card might not support recording of your chosen
              source. In this case, you are in bad luck. Most notably, many C-
              Media based cards do not allow recording while SPDIF out  is  in
              use.  You can try a setup using an "aloop" dummy card - but that
              process is far beyond the scope of this README,  and  with  most
              distributions,   it  requires  kernel  or  ALSA  re-compilation.
              However, in this case the PulseAudio input  driver  might  still
              give you the desired results.
