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)
