mactooloud. The per-app volume mixer macOS forgot to ship.
mactooloud is a native SwiftUI menu-bar app that turns the single macOS volume control into a per-app mixer. Boost one app, mute another, route a third to different speakers, and let music duck automatically when a call starts. All audio processing happens on-device.
