addressed How do you turn off the auto audio duck?

The feature doesn't allow me to fine tune audio the way I want.

The ducker works quite well.  Look under the Audio tab in OPTIONS and experiment with the settings.

To disable it, right click the audio tracks and UNcheck BACKGROUND SOUND.

Background sound is unchecked for this waveform and all the other ones yet it still ducks the audio.

I've been messing around with the numbers in the settings as well but to no effect.

What version of VP is being used?  Install the latest.  For licensed users upgrades are free for up to six months from purchase date.  After that, VP will continue to fully function but a fee will be required in order to register the newest.  Retain your old install file and registration info.

If that's still the case, then something is wrong.  Share the project so it can be analyzed.  It easy and can be done privately.  Just follow these steps...

•     Back up --- With your project on the timeline, click on MENU at the top-left.  Click FILE|BACK UP PROJECT FILES TO FOLDER.  Choose a folder and SELECT FOLDER.
•     Upload ---  Use a free server - Google Drive, MS OneDrive, etc.* - to upload the saved, numbered FOLDER.    Do NOT upload the individual VPJ or export file. 
•     Get link --- Get a public link.  If using Google Drive click GET SHAREABLE LINK. If necessary change "restricted" to "anyone with the link can view" 
•     Share ---     Click COPY LINK | DONE.  Paste that link here, or click the folder at the top-right of this forum to message it privately to me.  It won't be shared.

          *    Before uploading, right-click the folder, click PROPERTIES.  Look at the File Size to confirm that it's not too big for the free space on the server.
