Ducking controls
Adjust the ducking level on Mac
The right ducking level depends on whether background audio should almost disappear or stay gently audible while you speak.

Can you choose how much Mac volume is lowered?
Auto Ducking lets you choose how much Mac background audio is lowered when the microphone is active. The ducking level sets the quieter volume, while restore delay controls when the previous volume comes back after microphone use ends. Fade down and fade restore settings make the change feel less abrupt. You can also use presets for calls, dictation, recording, streaming, or custom workflows, remember different ducking levels for supported output devices, and use hotkeys for pause, restore, manual ducking, or opening the control panel. Auto Ducking focuses on system output volume and microphone activity. It does not process, record, transcribe, or upload microphone audio.
Ducking controls worth tuning
A good setup is predictable: quiet enough to speak, not so quiet that background audio disappears unless you want it to.
Ducking level
Choose the lower background volume while the microphone is active.
Restore delay
Delay volume restore so short pauses do not create jumpy audio.
Fade timing
Use fade down and fade restore to make volume changes smoother.
