Cadence-JackMeter is a digital peak meter for JACK.
It automatically connects itself to all application JACK output ports that are also connected to the system output.

This tool can be executed as 'cadence-jackmeter' for monitoring outputs or 'cadence-jackmeter -in' for monitoring inputs.

This is a regular digital-audio peak meter as you probably have seen many times before.
Note that the peak values are based on programming data (0.0 <-> 1.0) and not dB.

The meter has small lines to guide you. The value of these lines are (from bottom to top):

Usage

Simply run it and it will automatically connect to all JACK audio ports currently outputting sound to the 'system' client (or inputs if using '-in' argument).
The JACK client name is 'M' for "meter". When you change connections in the JACK graph, Cadence-JackMeter will change accordingly.
