Sonora 0.2.0

Per-app volume control for macOS, right in your menu bar.

Install

1. Download Sonora-0.2.0.dmg below, open it, and drag Sonora onto Applications.
2. Open Sonora. macOS says it can't verify the developer, because Sonora isn't notarized by Apple yet. Click Done.
3. Open System Settings → Privacy & Security, scroll down and click Open Anyway next to Sonora. You only need to do this once.
4. The welcome window walks you through the audio permission.

Requires macOS 14.2 or newer. Runs natively on Apple Silicon and Intel.

What's in it

• One slider per playing app, 0–150%, with a click on the icon to mute. Levels are remembered per app.
• Look-ahead limiter, so boosting never crackles or clips.
• Calls (WhatsApp, FaceTime, Zoom…) are detected automatically:
  • other apps fade down so your music doesn't leak into the call, and fade back gently afterwards
  • voices are leveled to a steady loudness when people join or leave
  • a separate call volume
  • when the call is the only thing playing, Sonora steps aside entirely
• A tip for macOS Voice Isolation, the strongest filter for your microphone.
• Detects a missing System Audio Recording permission and never leaves an app silent.
• Welcome window, open at login, and an animated menu bar title.

Known limitations

• An app whose volume isn't 100% is heard about 60 ms late (macOS's tap path).
• Not yet notarized, hence the one-time Open Anyway step.
