Quick Start

1. Install FineTune and launch it from your Applications folder
2. Grant Screen & System Audio Recording permission when prompted
3. Click the FineTune icon in your menu bar. Apps playing audio appear automatically.

That's it. Adjust sliders, route audio, and explore EQ from the menu bar.

Features

🎚 Volume Control

• Per-app volume — Individual sliders and mute for each application
• Per-app volume boost — 2x / 3x / 4x gain presets
• Pinned apps — Keep apps visible in the menu bar even when they're not playing, so you can configure volume, EQ, and routing in advance
• Ignore apps — Completely disengage FineTune from specific apps. Tears down the audio tap so the app returns to normal macOS audio

🔀 Audio Routing

• Multi-device output — Route audio to multiple devices simultaneously
• Audio routing — Send apps to different outputs or follow system default

• Auto-restore — When a device reconnects, apps automatically return to it with their volume, routing, and EQ intact

🎛 EQ & Correction

• AutoEQ headphone correction — Search thousands of headphone profiles or import your own ParametricEQ.txt files for per-device frequency response correction
