Jack Meter

Jack Meter is a basic console based DPM (Digital Peak Meter) for JACK. I wrote it for quickly checking remote signal levels, without having to run X11 to use a pretty graphical meter such as meterbridge.

Usage

Usage jack_meter [-f freqency] [-r ref-level] [-w width] [-n] [<port>, ...]

where  -f     is how often to update the meter per second (8)
       -r     is the reference signal level for 0dB on the meter
       -w     is how wide to make the meter (79)
       -n     changes mode to output meter level as number in decibels
       <port> the ports to monitor (multiple ports are mixed)

Screenshot

Registering as 'meter-01'.
Connecting 'alsa_pcm:capture_1' to 'meter-23750:meter'...
