volume mixerFaders gives every app its own volume slider. Turn the music down, the call up, boost a quiet video to 200 %, and get working volume keys on any display. It lives in the menu bar and uses 0 % CPU when idle.

This is the real Faders panel. Press play and every app makes sound, so you can hear what each slider does.
All sound is generated in your browser. Nothing is recorded.
Try the orange boost zone past 100 %, the mute buttons, and “Start a call”. The app looks and works just like this.
macOS has one volume for everything, so the Slack ping is as loud as the call and the video is too quiet to hear.
Faders gives each app its own slider, mute and output device, and remembers them. Browsers and Electron apps play through a dozen helper processes; Faders groups them so Chrome is one row, not twelve.
Push any app past 100 % for quiet calls and videos. A limiter keeps the sound clean instead of letting it distort.
Calls in your headphones, music on the speakers. If a device disconnects, the app moves back to your normal output.
Apps you haven't touched are never processed. When nothing is playing, Faders sleeps completely: no polling, no timers.
Three small annoyances every Mac user hits on video calls, fixed automatically.
When a Bluetooth headset's mic is used, macOS drops your music into muffled "call mode". Faders keeps the Mac's own mic, so everything keeps sounding right.
When Zoom, Teams, Meet, FaceTime, Slack or Discord uses the mic, other apps fade down and come back when the call ends.
A global shortcut mutes all your microphones, including the ones an app picked for itself, and restores them exactly as they were.
Monitors connected over HDMI or DisplayPort have no volume control on a Mac. The keys show a crossed-out speaker and do nothing.
Faders adds the missing volume in software. Your volume keys work again, with an on-screen indicator that looks like it belongs. Press the keys to try it.
Rank your outputs and microphones, and mark the ones macOS should never switch to on its own, like the monitor you never want sound from.
Faders only steps in when macOS switches by itself. If you pick a device, your choice always wins. Alert sounds follow your output instead of staying behind.

To change an app's volume, macOS asks you to let Faders “record” system audio. Faders only adjusts the sound live. It never records, saves or sends a single sample.
Built on Apple's own audio APIs. Nothing to install at the system level, no restart, no reduced security.
No account, no tracking, no telemetry. Faders doesn't know which apps you use or when.
It checks your license. That's it. Everything else happens on your Mac.
The earlier you buy, the less you pay. The price goes up as each launch batch sells out.

No. macOS calls the permission “record system audio” because that's the API that lets an app take over another app's sound. Faders uses it to change the volume live, in memory, and immediately plays it back. Nothing is saved, and Faders makes no network request except the license check.
No. Older mixers installed a virtual audio driver that broke with macOS updates. Faders uses the audio-tap APIs Apple added in macOS 14.2, so there's nothing to install and nothing to uninstall.
Faders uses 0.0 % CPU and about 15 MB of memory when nothing is playing. Apps you haven't adjusted are never processed at all. When an adjusted app goes quiet, Faders sleeps again within seconds.
Only apps you actually adjust pass through Faders, which adds about 60 ms. That's a limit of Apple's audio system and is the same for every app of this kind. Apps you leave at 100 % are untouched and have no delay.
Yes. Faders also keeps your Mac's built-in mic in use when Bluetooth headphones connect, so your music doesn't drop into low-quality call mode. If you choose the headset mic yourself, Faders remembers and leaves it alone.
No. Browsers play every tab through one audio process, so Faders controls the whole browser. You can still turn the browser down while leaving your music and calls where they are.
The App Store doesn't allow the permissions Faders needs for volume keys on external displays. You buy it here, and it's signed and notarized by Apple like any other Mac app.
