I’ve been looking for a tool like this for a long time, and FineTune finally checks all the boxes. It’s basically the volume mixer macOS should have shipped with: true per-app volume control with individual sliders and mute.
It also supports multi-device output, flexible audio routing, input and mic level control, a 10-band EQ with presets, pinned apps, and volume boost up to 400%, all in a lightweight menu bar app.
> brew install –cask finetune
