NAME
       fische - standalone sound visualisation

SYNOPSIS
       fische [options]

OPTIONS
       -D --driver driver

              Use  the specified audio input driver. Presently alsa,
              pulse, portaudio and dummy are supported.

       -d --device device

              device names the pcm capture device to get  the  sound
              data  from.  On most systems, the default will do just
              fine. This  Option  is  ignored  with  the  PulseAudio
              driver.  The PortAudio driver knows the special device
              help, which will spit out a list of all known devices.

       -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 applica‐
              tion window. Use this to prevent  your  computer  from
              trying  to  switch  to non-existent fullscreen resolu‐
              tions. CAUTION: when specifying  a  virtual  geometry,
              set the actual geometry FIRST!

       -f --fullscreen

              Start fische in fullscreen mode.

       -e --extra-nervous

              Start fische in nervous 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

       --exit-on-mouseevent

              Exit when a mouse button is clicked (useful mainly  on
              touchscreens)

       -n --nowrite

              Do  not  update  the  configuration file with the last
              known working configuration.

       -h --help

              Display a basic help message.

RUNTIME CONTROLS
       At runtime, press P to pause, F to toggle fullscreen mode,  N
       to  toggle  nervosity  and  ESC  to quit. With the --exit-on-
       mouseevent flag, fische does exactly that.

KNOWN ISSUES
       PortAudio is currently slow on Linux. If able, use a  differ‐
       ent driver.

       On  Windows,  the  actual frame rate is often quite different
       from the specified one. The actual rate is shown after  exit.
       Use the -s flag to increase it to about 30.

TROUBLESHOOTING (Linux only)
       If  you  get  an  error like "X Error of failed request: Bad‐
       Value..."

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

       If fische starts, but won't 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 cor‐
              responding "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 configura‐
              tion 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 man page, and with
              most distributions, it requires kernel or ALSA re-com‐
              pilation.  However,  in this case the PulseAudio input
              driver might still give you the desired results.
