Utilities / Productivity

Mic on. Volume down. Auto restore.

Auto Ducking watches microphone activity, lowers system output volume to your chosen level, and restores the previous volume when speaking ends.

  1. 01

    Any microphone app becomes active.

  2. 02

    System output volume fades down to the selected ducking level.

  3. 03

    When the mic stops, volume restores after your chosen delay.

Built for short mic moments and long calls

Auto Ducking fits workflows where you want background audio present, just quieter while you speak.

Controls

Controls for real speaking patterns

Set separate presets for calls, dictation, recording, streaming, or your own workflow.

  • Adjust ducking level, restore delay, fade down, and fade restore.
  • Use every microphone app, selected apps only, or exclude apps you do not want to trigger ducking.
  • Remember different ducking levels for speakers, headphones, displays, and other output devices.
  • Use global hotkeys to pause Auto Ducking, restore volume, trigger manual ducking, or open the control panel.

Privacy

Private by design for a microphone utility

Auto Ducking does not record audio, transcribe speech, or upload microphone audio. It detects microphone activity and adjusts system output volume.

  • Settings, presets, output-device memory, hotkeys, and usage statistics are stored locally on your Mac.
  • Usage insights track timing and volume changes, not recordings, transcripts, or app usage details.
  • If an output device cannot be controlled by software, Auto Ducking shows a clear unsupported-output status.

Let background audio step back while you speak

Set the level once, keep your audio playing, and stop reaching for the volume keys every time your microphone turns on.
