Auto Ducking is a Mac menu bar utility for mic ducking. When any app starts using your microphone, for a call, dictation, recording, streaming or an AI voice chat, it fades your Mac's system output volume down to the level you choose, then restores the previous volume when microphone use ends. Set ducking level, restore delay and fade timing, use presets, app trigger rules, per-output-device levels and global hotkeys. It never records, transcribes or uploads audio. 7-day full trial, then a one-time Lifetime Unlock.
