macOS has no built-in per-app volume control. Your music is too loud while a podcast is too quiet. FineTune fixes that:
- Turn down notifications without touching your music
- Play different apps on different speakers
- Boost quiet apps, tame loud ones
- Free forever, no subscriptions
- macOS 15.0 (Sequoia) or later
- Audio capture permission (prompted on first launch)
FineTune can apply headphone-specific frequency response corrections using profiles from the AutoEQ project.
Browse built-in profiles — Click the wand icon next to any headphone device and search for your model. Profiles are fetched on demand and cached offline.
Import custom profiles — Click "Import ParametricEQ.txt..." at the bottom of the AutoEQ panel. FineTune accepts EqualizerAPO ParametricEQ.txt files:
Preamp: -6.2 dB
Filter 1: ON PK Fc 100 Hz Gain -2.3 dB Q 1.41
Filter 2: ON LSC Fc 105 Hz Gain 7.0 dB Q 0.71
Filter 3: ON HSC Fc 8000 Hz Gain 2.1 dB Q 0.71
Supported filter types: PK/PEQ (peaking), LS/LSC (low shelf), HS/HSC (high shelf). Up to 10 filters per profile.
You can download ParametricEQ.txt files from autoeq.app — select EqualizerAPO ParametricEq as the equalizer app — or create your own in any text editor.
No sound / audio stops working? Grant Screen & System Audio Recording permission in System Settings → Privacy & Security. Restart FineTune after granting.
App not appearing? Only apps actively playing audio show up. Start playback first. If an app is hidden, open edit mode (pencil icon) and look for the eye icon.
App causing audio issues? Some apps (audio processors, VoIP tools) don't work well with process taps. Use edit mode to ignore the app — this tears down its tap entirely.
Volume slider not working? Some apps use helper processes. Try restarting the app.
Input devices not showing? Grant microphone permission in System Settings → Privacy & Security → Microphone.
Control FineTune from Terminal, shell scripts, Shortcuts, Raycast, or any app that can open URLs.
