jack_meter_simple

A simple script that displays amplitude in db of the output of a jack device as plain text. This is a fork/rework of Nicholas J. Humfrey's jackmeter but with a much more simplified output that works well with status bar programs like i3blocks and i3status.

Example command

Run the command:

jack_meter_simple SuperCollider:out_1

Set several ports (which will be mixed to mono before analysis)

jack_meter_simple "PulseAudio JACK Sink:front-left" "PulseAudio JACK Sink:front-right"

Example i3blocks config

[jack_db]
align=left
command=$HOME/code/c/jack_meter_simple/jack_meter_simple SuperCollider:out_1
interval=persist
label=<span color="#B57614">db: </span>

Building

git clone https://github.com/madskjeldgaard/jack_meter_simple

./autogen.sh && make
