LEVELS
A native per-app volume mixer for macOS. Turn one app down without touching the rest.
Shipped · notarized macOS release
Shipped and available at uselevels.app.
OVERVIEW
Levels gives every running app its own volume slider. A loud browser tab can come down while music and calls stay exactly where they are.
It is a finished, notarized macOS product with licensing, distribution, and a complete public product surface.
THE BUILD
The application is native Swift and SwiftUI on top of Core Audio taps. Product work included the audio system, interaction model, code signing, notarization, licensing, distribution, and launch site.
WHAT'S NOVEL
Levels provides per-application gain on macOS without placing a virtual audio device in the signal path.
