Usage

Overview

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 soundcard.

Options

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.

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)

-M, --max maximun_latency

Set the highest allowed latency to maximun_latency samples (default 1024)

-r, --rate rate

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)

Options

-C, --cconnect <LEFT,RIGHT>

jack-connect to the specified capture client jack ports (default: none)

-P, --pconnect <LEFT,RIGHT>

jack-connect to the specified playback client jack ports (default: none)

-a, --alsaconnect

jack-connect to alsa_pcm.
