Why Faders exists

Spotify drowns out your Slack call. Again.

Most of us run four to six audio-producing apps at once. A music player, a chat app, a meeting client, a browser playing something in a background tab, the system, and whatever Pomodoro timer is supposed to make us focus. macOS gives you exactly one volume knob to control all of it.

The existing options haven't held up. The free open-source tools break with every macOS update — you find out the moment a meeting starts. The professional audio suites cost $49 and bundle features no one needs to turn down Spotify during a Zoom.

Windows shipped a per-app volume mixer in 2007. macOS still hasn't, in 2026. So we built one.

How it works

Three things. Done well.

One per app

One slider per app. That's it.

Every audio-producing app on your Mac gets its own volume slider. Drop Spotify to 20% during a call. Mute Slack notifications without quitting Slack. Adjust your browser tab without touching your music.

Output routing

Send each app to the right device.

Music to your speakers. Zoom to your AirPods. Slack notifications to nothing at all. Faders remembers your routing choices and restores them when devices reconnect.

Audio Scenes

Meetings shouldn't require five clicks.

Save your perfect audio configuration as a Scene. When Zoom opens, Meeting Mode activates: Spotify drops to 20%, Slack mutes, system sounds quiet. When Zoom closes, everything restores. Set it once, never think about it again.

The privacy story

What Faders does not do.

After Bartender's quiet acquisition in 2024, the Mac community learned the hard way that menu bar utilities can become liabilities overnight. Faders is built so that can never happen here.
