Per-app sliders

One volume slider per running app that's making sound. Drag one down without touching system volume or any other app.

One-click mute

Mute a single noisy app instantly — no digging through its own settings.

Lightweight, on purpose

Built to stay out of the way: no bundled effects engine, no background bloat. Just the mixer.
