SoundTune — Per-App Volume Mixer for the Mac Menu Bar
SoundTune is a small menu bar app that gives every app on a Mac its own volume. Turn a noisy browser tab down to a whisper while the music stays where it is, mute a game without pausing a call, or push a quiet meeting past 100%. Output devices and their volumes sit in the same panel. It suits anyone who juggles sound from several apps at once and is tired of one system volume for all of them.

One licence, personal and client work, forever. No resale.
SoundTune puts a mixer behind a fader icon in the Mac menu bar. Every app that is playing sound gets its own slider, so one app can be turned down, muted or boosted while everything else carries on untouched.
One slider per app
Each app playing audio appears with its own volume, from silent to a boost above 100%. The setting is remembered, so an app that is always too loud stays turned down next time it opens.
Mute one, keep the rest
Silence a noisy tab, a game or a notification sound without pausing the music or missing a word of a call.
Outputs in the same panel
Speakers, headphones or a display: switch the output in a click and set its volume without opening System Settings.
Turn a quiet app up
Push a quiet video or a soft-spoken meeting past 100%, with a limiter that keeps the boost from clipping.
Mute everything, instantly
A right-click on the menu bar icon silences every app at once, and a second right-click brings it all back.
How it works
- Left-click the fader icon opens the mixer: your output devices at the top, then every app that is playing sound, each with its own slider from silent to 200%.
- Drag an app's slider to set its volume, or click the speaker button beside it to mute just that app. Double-click a row to put it back to 100%.
- Click a device to make it the output, and use its slider for the device volume.
- Right-click the icon, or Control-click it, to mute every app at once, and again to bring them all back.
- The options menu holds Reset All Volumes and Open at Login. Each app's volume is remembered for next time.
Opening it the first time
SoundTune is signed and notarized by Apple, so it opens with a normal double-click.
Why does it need macOS 14.4?
Per-app volume relies on the audio tap support Apple added in macOS 14.4 Sonoma. On earlier versions there is no way for an app to do this without installing an audio driver, which SoundTune deliberately avoids.
Why does macOS ask about system audio?
Setting one app's volume means taking over that app's audio and playing it back at the level you chose, and macOS asks permission before any app can do that. Nothing is recorded, saved or sent anywhere.
What happens when SoundTune is not running?
Audio goes straight to the output device as usual. Apps are only routed through SoundTune while a slider is away from 100%, and quitting the app puts everything back.
Which Macs does it run on?
Any Mac with Apple silicon or Intel running macOS 14.4 Sonoma or later.
