MarcX Studio Comparison guide
Auto Ducking focuses on one moment, the microphone turning on, and handles it for you. That focus keeps setup quick and daily use effortless.
01mic-triggered ducking vs volume mixers
Simple mic-triggered ducking is the right fit when the change you keep making is always the same: microphone on, background audio down, microphone off, volume back. A volume mixer gives you levels to set by hand; Auto Ducking makes that change for you the moment any app turns the microphone on, then restores the previous volume after your restore delay. You set the level once per sound output, choose which apps trigger it, save presets, and keep everything one click away in the menu bar or on a global shortcut. Calls stay at full volume by default, and Auto Ducking never records or uploads audio.
02Controls
Auto Ducking turns a repeated manual volume change into something that happens on its own.
01
The volume drops when the microphone turns on and fades back when it turns off, with no sliders to touch.
02
Lower to level, restore delay, fades and app rules are remembered per preset and sound output.
03
The menu bar panel and global shortcuts cover pause, Restore Now and Manual Lower.
Dictation, recording, voice chats or calls: note when you usually reach for the volume keys.
Choose the Lower to level, restore delay and fades for each sound output.
Use every microphone app, only the apps you pick, or skip the ones you want left alone.
Let Auto Ducking run quietly and step in with shortcuts when you want to.
03FAQ
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.
Auto Ducking waits for your restore delay, then fades your previous volume back. To bring it back straight away, press Restore Now.
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.
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.
One automatic step: when any app turns the microphone on, the system volume fades to your chosen level, and it comes back when the microphone turns off. Per-output levels, app rules, presets and global shortcuts let you shape that step to your workflow.
If your main pain is manual volume changes when the mic turns on, Auto Ducking is built for that.
