If you create video or audio content Auto-Duck in Real Time is a must-have tool for you.
Improve audio quality, your audience deserves it!

Sample use case (The Sims and OBS are just examples):
Let's say you are streaming the game The Sims using Open Broadcaster Software (OBS) and want to lower game volume on your commentary. You can select your microphone as Input Channel and The Sims as Channel to Duck. After configuring threshold for Input Channel, max and min volume of Channel to Duck and fading you are good to go.
In such a setup, you will hear changing game volume for yourself. If you don't want it you can select OBS as Channel to Duck and your viewers will still hear ducked game audio and you will hear original game audio (not ducked).

Version 2.2 is having some problems. Don't worry Auto-Duck'S programer is working hard with corrections as he said to me by email. This program is simple THE BEST PROGRAM FOR A STREAMER WHO WANTS TO ADD AMAZING SOUND CONTROL. Is the only program in the world who can auto duck ANY audio source from your PC. ANY SOURCE! IS FREAKING AWESOME.
Yep, it's finally here!
Highly improved, fixed, and refreshed Auto-Duck v3.0-RC1:
Enjoy! :)
I've been using this application for a number of years now, for the simple fact that it's the only thing I can find for this purpose. But, I can't give it a passing grade just because it does the thing I need it to do. I've had COUNTLESS issues, crashes, and other nonsense to deal with this thing, and it's extremely frustrating. I can't even close the application without it crashing, and deleting my profiles entirely. I would love to know how many of these 5-star reviews actually used this app for any extended period of time...
Please try highly improved, fixed, and refreshed Auto-Duck v3.0-RC1:

PS. There was no one crash on beta tests :)
Auto-Duck works as expected.
Excellent customer service.
Nice application
Cannot recommend this enough. An easy to use program to easily add some production value to your streams/recordings. Use promo code ACHMETHA for 10% discount (or more).
This program is amazing and because of it you don't have to fiddle with finding a good balance between sound and voice. Made my life so much easier :)
With the addition of the boost it should now work for everyone, even with very quiet Microphones. Keep up the good work :)
