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

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)
