What is a Mac auto ducking app?

A Mac auto ducking app lowers background audio when the microphone turns on and brings it back when the microphone turns off. Auto Ducking does this from the menu bar: it fades the system volume down to your Lower to level, waits for your restore delay, then fades it back. You get a separate level for each sound output, presets for dictation, recording, podcast prep or your own setup, app rules, Manual Lower, Restore Now and global shortcuts. Calls stay at full volume by default, so the volume drops when music or video is playing under your voice. Auto Ducking only checks whether the microphone is in use and never records or uploads audio.

Who needs auto ducking on Mac?

Auto ducking fits people who speak often on a Mac and want fewer manual volume changes.

01

Voice-first Mac users

Useful for dictation, voice input, AI voice chats, and voice notes.

02

Meeting-heavy users

Calls stay at full volume so you hear everyone, and music still steps back when you dictate between meetings.

03

Creators and streamers

Save a preset for recording or podcast prep, and use Manual Lower to bring the volume down before you start.

What Auto Ducking controls

  1. 01

    Choose the Lower to level

    Set how quiet background audio gets while the microphone is on. Speakers, headphones, displays and AirPods each keep their own level.

  2. 02

    Set the restore delay and fades

    Fade down, wait a moment after the microphone turns off, then fade back, so short pauses never make the volume jump.

  3. 03

    Pick the apps

    Let every microphone app trigger Auto Ducking, only the apps you choose, or every app except the ones you skip.

  4. 04

    Keep control from the menu bar

    Use the status panel or global shortcuts to pause Auto Ducking, Restore Now, Manual Lower, or open the panel from any app.

03FAQ

Mac auto ducking FAQ

What does Auto Ducking do with my microphone?

It checks whether the microphone is in use, and which app turned it on, then adjusts your Mac system volume. Auto Ducking never records, transcribes or uploads audio.

What happens when the microphone turns off?

Auto Ducking waits for your restore delay, then fades your previous volume back. To bring it back straight away, press Restore Now.

Can I choose how much the volume is lowered?

Yes. Set the Lower to level from 0 to 20%, separately for each sound output, and tune the restore delay and fades. Save the combinations you like as presets.

What happens during a video or voice call?

With “During Calls” on, which is the default, the call stays at full volume so you hear everyone, and Auto Ducking lowers the volume only when something else is playing, like music while you dictate. To lower every time the microphone turns on, switch off “During Calls” in Settings > Ducking.
