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
--alsa Use ALSA, same as running tapiir_alsa
--jack Use JACK, same as running tapiir_jack
Show summary of options.
-P, --pdevice playback_device
Set the ALSA device to use for audio output to playback_device
-C, --cdevice capture_device
Set the ALSA device to use for audio input to capture_device
-m, --min minimun_latency
Set the desired latency to minimun_latency samples (default 256)
Set the sampling rate to rate Hz (default 48000)
Use blocking access to the audio device (not used by default)
-t, --time time
maximal tick time in us
Use polling access to the audio device (used by default)
