Fader

You want to adjust one app's volume or quickly switch input/output devices, but the system volume control isn't enough. Fader lives in the menu bar: a menu bar volume mixer with per-app volume, set each app's volume separately in the menu bar and switch input/output devices fast, like a mixing desk on hand, handy while watching video, meeting or listening to music. A macOS app, open source.

Features

Per-app volume: Set volume per app.

Device switching: Switch input/output devices fast.

Menu bar mixer: A volume mixer in the menu bar.

Open and free: An open-source project, free to use.
