meterbridge for Jack Audio Connection Kit

## NAME

meterbridge - meterbridge for Jack Audio Connection Kit

## SYNOPSIS

**meterbridge** \[*options*\] *portname* \[portname\] *...*

## DESCRIPTION

This manual page documents briefly the **meterbridge** program.

This manual page was written for the Debian distribution because the original program does not have a manual page.

meterbridge shows the signal values of the audio signals that flow through JACK ports. The possible representations include the classical VU meter, as well as PPM meter, Digital Peak meter and others. See the OPTIONS section for more information.

## OPTIONS

A summary of options is included below.

- **-r rev-level**

  Use rev-level as the reverence level for 0db on the meter.

- **-c columns**

  number of columns that are used for displaying several meters.

- **-n jackname**

  Use jackname as identifier with the JACK system.

- **-t type**

  Use the one of the following meter types:\
        'vu'  - classic moving needle VU meter\
        'ppm' - PPM meter\
        'dpm' - Digital peak meter\
        'jf'  - 'Jellyfish' phase meter\
        'sco' - Oscilloscope meter

## EXAMPLES

      test with\
          meterbridge -t vu alsa\_pcm:capture\_1 alsa\_pcm:capture\_2

      if you want to see what your JACK system is outputting you can use:\
          meterbridge -t ppm alsa\_pcm:playback\_1 alsa\_pcm:playback\_2

      if you want to start a bridge with unconnected 4 meters:\
          meterbridge -t ppm x x x x\
       (or any other invalid port names)
