Every app. Its own volume.

macOS gives you one volume slider. teenysound gives you one for every app.

Per-App Sliders

Drag to adjust any app from 0 to 100% independently.

Per-App Mute

Mute individual apps with a single click. Unmute anytime.

System Volume

A master slider that controls overall output level alongside per-app mixing.

Live Detection

Apps appear automatically when they produce audio. Uses Apple's CATap API — no drivers needed.

Mix your apps like a soundboard.

teenysound shows every app that's producing audio with its own volume slider. Turn down your browser while keeping music at full blast, or lower a meeting while your notification sounds stay audible. Each slider goes from 0 to 100%.

Mute everything with one shortcut.

Press Option+Shift+A and every app goes silent instantly. A quick HUD overlay confirms mute is active. Press again to restore all volumes to exactly where they were. A second shortcut (Option+Shift+S) opens or closes the mixer from anywhere. Both shortcuts are fully customizable in Settings.

Route apps to different speakers.

Send Spotify to your headphones and a video call to your desk speakers — at the same time. teenysound lets you route individual apps to specific output devices. Your per-app volumes are remembered independently for each device and restored automatically when you switch.
