AI voice workflows can feel more natural when background audio stays available but gets out of the way while you speak.

How does Auto Ducking help AI voice chats?

Auto Ducking lowers your Mac background audio whenever you speak to an AI assistant. Dictating a prompt or holding push-to-talk turns the microphone on, so music or video fades down to your chosen level and comes back when you stop. For back-and-forth voice chats where the assistant answers aloud for a while, Auto Ducking treats the conversation like a call and keeps the volume up by default, so you hear every reply. If you want the music low for the whole chat, switch off “During Calls” in Settings > Ducking, and Auto Ducking lowers every time the microphone turns on. It only checks whether the microphone is in use and never records, transcribes or uploads audio.

Where it fits in AI voice work

Use it when you talk to AI tools often and want the music to make room for your voice.

01

Dictated prompts

Speak a prompt and the music steps back, then returns once the microphone turns off.

02

Push-to-talk

Each press turns the microphone on, so background audio drops while you hold and fades back when you let go.

03

Spoken conversations

For long voice chats where the assistant talks back, switch off “During Calls” so the music stays low every time the microphone is on.

FIG.01

Set up AI voice ducking

  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

AI voice chat 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.

What if the AI assistant talks back aloud?

A voice chat where the assistant answers aloud for a while is treated like a call, so the volume stays up and you hear every reply. To have the music lowered for the whole chat, switch off “During Calls” in Settings > Ducking.
