The best per-app volume apps for Mac

Windows has had a volume mixer for decades; macOS still has one slider for everything. Four apps that let you turn down Slack without turning down Spotify, and what each one installs to do it.

How we chose

We picked apps that can set a different volume for each app on current macOS and Apple Silicon. We compared how they do it, since that affects reliability: older tools install a virtual audio device that all sound passes through, while newer ones use the process taps Apple added in macOS 14.2.

A driver-based tool becomes your default output device, so if it crashes or an update breaks it, sound can stop entirely until you switch back in System Settings › Sound.

Which one should you pick?

  • Audio is your job, or you want per-app EQ and routing: SoundSource is worth the money.
  • You want a free mixer that installs nothing: Stat Space, on an Apple Silicon Mac with macOS 14.2 or later.
  • You mostly want a system EQ: eqMac.
  • You want free and open source and can live with alpha software: Background Music.

Quick fixes without an app

You can still get some of the way with what macOS has:

# Set output volume (0–100) from Terminal
osascript -e 'set volume output volume 40'

# Show audio devices and the current default
system_profiler SPAudioDataType

Click Sound in Control Center (or the menu bar, if you’ve added it) to switch output devices quickly. More options are in our guide to per-app volume on Mac.

Where Stat Space fits

We make Stat Space, and its Volume tab is free. It covers the everyday case well: turn a noisy app down, mute everything but your call, send music to the speakers while calls stay on headphones. If you need EQ or effects per app, SoundSource does far more.

We make Stat Space, so weigh our pick accordingly. Prices and features as of November 2026; spotted something out of date? Email [email protected].

Questions

Does macOS have per-app volume control?

No. macOS has one output volume for everything. Some apps (Zoom, Spotify, Music) have their own volume slider, but there’s no system mixer, so you need a third-party app.

Is there a free volume mixer for Mac?

Yes. Stat Space’s volume tab is free, and Background Music is free and open source. eqMac’s per-app mixer requires Pro.

Why does my Mac show a purple dot when I change an app’s volume?

Apps that use Core Audio process taps need System Audio Recording permission, and macOS shows a purple indicator while one is active. The audio is adjusted locally; it isn’t recorded or sent anywhere.
