Keep background audio under control while you dictate, record, join calls, or talk to AI. Try every feature free for 7 days. Auto Ducking lowers your Mac’s background audio when a microphone app becomes active, then restores the previous volume when microphone use ends. Keep music, video, or ambient audio playing while you dictate, join calls, record, talk to AI, prepare a podcast, or use voice input on your Mac. Set your ducking level once and let Auto Ducking handle the volume change from the macOS menu bar. TRY BEFORE YOU BUY Auto Ducking includes a 7-day full-feature trial. After the trial, Lifetime Unlock is required to keep automatic ducking enabled. KEY FEATURES • Automatic audio ducking When a Mac app starts using the microphone, Auto Ducking lowers system output volume to your chosen level. • Automatic restore When microphone use ends, your Mac volume returns to where it was before. • Smooth fade controls Use fade down and fade restore so volume changes feel less abrupt. • Adjustable ducking level Choose how quiet your background audio gets while the microphone is active. • Restore delay Add a short delay before volume comes back, so quick pauses do not cause volume jumps. • App trigger rules Use Auto Ducking with every microphone app, only selected apps, or exclude apps you do not want to trigger volume changes. • Presets for different workflows Set up reusable presets for calls, dictation, recording, podcast prep, or your own custom workflow. • Output device memory Keep separate ducking levels for supported speakers, headphones, displays, and other output devices. • Manual ducking Lower audio manually even when the microphone is not active. • Global hotkeys Pause Auto Ducking, restore volume, trigger manual ducking, or open the control panel without opening the menu. • Usage insights See how often Auto Ducking helps you avoid manual volume changes. • Menu bar only Runs quietly from the macOS menu bar with no Dock icon. PRIVACY Auto Ducking does not record audio, transcribe speech, or upload microphone audio. It detects microphone activity and adjusts your Mac’s system output volume. Usage statistics are stored locally on your Mac and can be reset.
