Per-app volume & boost

The heart of mixr: every app gets its own volume slider, independent of every other app and of your system volume.

Setting an app’s volume

Open mixr from the menu bar and you’ll see a slider for each app that’s playing audio. Drag it to set that app’s level. That’s it — the change is instant, and only that app is affected.

Your call stays where it is when you turn your music down. A loud game doesn’t force you to drop everything else to hear a video.

Boosting past 100%

Some apps are just too quiet — a video with low audio, an app that won’t go loud enough even at full system volume. mixr’s sliders go past 100%, so you can boost a quiet app louder than macOS normally allows, without turning everything else up with it.

Boost is per-app, like everything else: turn one thing up without affecting the rest.

It remembers

Set an app’s volume once and mixr keeps it there. Close the app, reopen it later — it comes back at the level you left it. You don’t have to reset it every time.

Apps that aren’t playing yet

mixr shows apps that are currently producing audio. If you want to set a level for an app that’s quiet right now, you’ll find it under recent apps — you can set its volume ahead of time, and mixr will apply it when the app plays.

Pinning apps you use often

If there are apps you always want at the top of the list, you can pin them, so they stay visible whether they’re playing or not. Right-click an app and choose Pin.

Muting is here too: each app’s speaker icon toggles it silent. And if you want to reset an app to normal volume, double-click its slider.
