# tapiir(1)

A software multitap delay with realtime I/O

## NAME

tapiir - A software multitap delay with realtime I/O

## SYNOPSIS

**tapiir** \[**--alsa** \[*alsa\_options*\] \| \[**--jack** \[jack\_options\] \] \[**-h** \| --help**\]**\
 **tapiir\_alsa** \[*alsa\_options*\]\
 **tapiir\_jack** \[*jack\_options*\]\

## DESCRIPTION

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.

## ALSA 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)

## JACK 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.
