01Auto Ducking FAQ

What should you know before using Auto Ducking?

Auto Ducking is a Mac menu bar app that lowers your system volume when the microphone turns on and restores it when the microphone turns off. Any app that turns on the microphone can trigger it, or only the apps you choose. You pick the Lower to level, restore delay and fades for each sound output. Calls stay at full volume by default, and Auto Ducking only checks whether the microphone is in use, so it never records, transcribes or uploads audio. Every feature is free for 7 days; after that, a one-time Lifetime Unlock keeps automatic lowering on, with no subscription. It runs on macOS 14 or later.

Common evaluation questions

Most questions fall into three groups: what triggers ducking, how the volume feels, and what happens to microphone privacy.

Trigger behavior

Auto Ducking reacts when an app turns the microphone on, with app rules for all apps, only chosen apps, or skipped apps.

Volume behavior

Lower to level, restore delay, fade down, and fade back control how the change feels.

Privacy behavior

The app checks only whether the microphone is in use and keeps usage stats on your Mac.

FIG.01

Start with these settings

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.
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.
03

Pick the apps

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

Auto Ducking questions

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.

Is there a trial?

Yes. Every feature is free for 7 days. After the trial, a one-time Lifetime Unlock keeps automatic lowering on. No subscription.

Does it run from the menu bar?

Yes. Auto Ducking runs from the macOS menu bar, with a status panel in light and dark, and global shortcuts for common actions.

Which sound outputs does it work with?

Auto Ducking remembers a separate level for speakers, headphones, displays, AirPods and other outputs. A few HDMI and USB devices only let the device itself set the volume; the status panel tells you when that happens, and you can use the volume control on the device.

How do I get started?

Install Auto Ducking on macOS 14 or later. A short welcome guide on first launch walks you through the basics, and you can test the lowering with music playing before your next voice session.
