GAKKEY LAB

Small macOS tools lab

Small tools for the little things
I wish I had.

I make macOS apps for my own creative workflow.
If they look useful to you, you are welcome to give them a try.

Bridge Meter & Bridge Plugin

A compact meter
made to stay in view.

Bridge Meter works with the Bridge Plugin and Mac audio input, and can also capture audio directly from your Mac with no complex setup. Just select “System Audio Out” as the input and start metering.

Detach the panels you want
to keep in view.

The Loudness and Analyzer panels can be detached temporarily.
Reference Level can also be adjusted to suit your workflow.

Bridge Plugin System Audio Input System Audio Output AAX / VST3 / AU
Bridge Plugin window

Bridge Plugin is also included.

Add the AAX / VST3 / AU Bridge Plugin to your DAW to send display data directly to Bridge Meter. It offers lower latency than System Audio Out and excludes audio from other apps. The plugin only sends metering data and does not alter the audio itself.

System Requirements macOS Sonoma 14.2 or later / Universal Binary (Apple silicon and Intel)
