About
macOS still has no built-in per-app volume control. Sonance Mixer adds it — a menu-bar mixer with a separate volume slider and mute for every app currently playing sound.
GREAT FOR
• Turning a loud game down without touching your Discord call
• Keeping background music quiet while you're on Zoom
• Instantly muting one noisy browser tab or app — not everything
• Sending a movie to your speakers while notifications stay on your headphones (Pro)
No driver, no kernel extension, no reboot. Sonance Mixer uses Core Audio process taps (macOS 14.4+), so it installs like any normal app and adjusts every level live, with no clicks or glitches.
FEATURES
• Independent volume + mute for every app playing audio
• Per-app output routing (Pro) — send different apps to different devices
• Driverless and lightweight — lives quietly in your menu bar
• Smooth, real-time changes with no zipper noise
Free: volume + mute for every app. Pro (one-time purchase): per-app output routing.
Your audio is processed live on your Mac and never leaves it.
