Mute the app, not the whole Mac
The keyboard mute key silences the current system output. If you only want to silence a browser, game, or media app, a per-app mute control avoids interrupting everything else.
VolumeDirector places a mute button on each app row. Muting one row does not change the volume of other apps or the Mac’s master output.
Mute a single app

When an app is not visible
An app normally appears after it begins producing audio. Recently active and pinned apps can also stay visible. If an app is missing, start playback, confirm System Audio Recording access is enabled, and reopen the menu.
