VolumeMixer
Every app gets its own volume slider.
Music too loud over your call? Chrome screaming over your podcast? VolumeMixer lives in your menu bar and lets you set independent volume and mute for every running app.
Features
Per-app faders
Independent volume and mute for each running app — turn Chrome down without touching your music.
No drivers. No hacks.
Built on Apple's modern CoreAudio Process Tap API. No kernel extensions, no virtual audio devices, no reboots.
Zero-touch passthrough
Apps at 100% stay on their native audio path, completely untouched. VolumeMixer only steps in when you move a slider.
Master channel
A system-wide "All Sound" fader that works with every output device — even HDMI displays without hardware volume.
Remembers everything
Your levels are saved per app and restored automatically the next time the app plays audio.
Private by design
Audio never leaves your Mac. No analytics, no network calls, no accounts. Ever.
