       This manual page documents briefly the tapiir application.

       tapiir  is  a  software  multitap  delay  with realtime audio I/O. It's
       internal processing modules consist of six  delay-lines,  each  with  a
       mixer  at  it's  input  and a gain control at it's output, and a stereo
       output mixer. Stereo input from an external source, typically a musical
       instrument,  is  routed  to  all input mixers. In addition to this, the
       output of each delay line is also routed to the  input  mixers  of  all
       delay lines, including itself.

       For  a detailed explanation of the multitap delay technique, and a more
       comprehensive description of tapiir capabilities and internals, see the
       document referenced in the SEE ALSO section below.

       A   set   of   example   configuration   files   are  provided  in  the
       /usr/share/doc/tapiir/examples directory, which offer a  good  overview
       of  the  things  you  can achieve using tapiir, and also provide a good
       starting point to learn to use it.

       To run tapiir, you need either the ALSA sound system or the JACK  audio
       server,  and  the  audio from your musical interpretation fed into your


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

       --alsa Use ALSA, same as running tapiir_alsa

       --jack Use JACK, same as running tapiir_jack

       -h, --help
              Show summary of options.

       -P, --pdevice  playback_device
              Set the ALSA device to use for audio output  to  playback_device
              (default "hw:0,0")

       -C, --cdevice  capture_device
              Set  the  ALSA  device  to use for audio input to capture_device
              (default "hw:0,0")

       -m, --min  minimun_latency
              Set the desired latency to minimun_latency samples (default 256)
              Set the sampling rate to rate Hz (default 48000)

       -b, --block
              Use blocking access to the audio device (not used by default)

       -t, --time  time
              maximal tick time in us

       -p, --poll
              Use polling access to the audio device (used by default)
