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.


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


      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:
