       This  manual  page  was written by Guenter Geiger <geiger@debian.org>, for the Debian project (but may be
       used by others).

                                                 April 11, 2012                                   METERBRIDGE(1)

       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.

             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)
