Corel VideoStudio - Problems with Audio Ducking

[Wanderings]

Hi,
I've recently bought Corel VideoStudio Ultimate 2022 and can't understand how to use audio ducking in the way i want.
I have a video track (with sound), a voiceover track and a background music track.
When I turn on audio ducking on the music track, it recognises the sound on the main video track and ducks properly. But no matter what I try, it doesn't seem to duck for the voiceover track when that has sound on it.
(I mean that the background music is not ducking down when there is speech on the voice track)

What am I doing wrong? Am I missing something obvious? I've tried turning up the levels of the voiceover track, so I don't think it's a loudness/sensitivity issue.

Help please!

Some people have managed to get good results, would like to learn how. I assume you cleaned the audio so that it has no background noise, and then tweaked the sensitivity and then tweaked the gain. The sensitivity setting gave odd results after sliding it all over the place and running it about on 12 different levels I found one that was roughly OK. I used Audacity to first silence background noise and then normalised the audio as well, before importing as mp3. I guess once you get the hang of it, it probably does work well, but it was not as sweet as I had hoped. I'm not sure how people get good results, I ended up doing a lot of manual fixups I'll probably not bother with it in future unless someone specifically asks or requires me do it. As with all things, it will take a few goes. How long is the speaking for? Might be easier in Audacity https://manual.audacityteam.org/man/auto_duck.html.

Audio ducking has been the topic of several issues posted over recent years. I suggest you search for those and review the suggestions made in them.

I've found audio ducking might get me in the "ball park" so adjusting, while still necessary, is slightly easier. But if I have to do some ducking, I'll do it manually.
