Synching audio from two different sources

I have audio from two different sources: YouTube and our soundboard. The gentlemen on the soundboard were monkeying too much, and there are drastic changes in 4 different sections of the YT audio file. The audio from the soundboard sounds much better and does not have these jarring changes of tone and such in it.

I want to take audio from the soundboard and replace it in the YT file, but the time/length is noticeably off and out of synch by several seconds at the end of the file. Is there a way to fix this beyond chopping it up and using small sections at a time? If there is, I would be more inclined to drop the YT audio and replace it with the soundboard version. But again, audio and video would be wildly out of synch.

I'm currently using Audition build 25.3.0.71

So, if I understand correctly, you want to sync the soundboard file to the YouTube video?

This should be fairly easy to do in Premiere. Select the YouTube video, then the soundboard audio. Right click, select merge clips, choose the Youtube audio as the synchronize point.

See this page.

Sorry if I've misunderstood and you've already tried this.

Thank you, but unfortunately, this didn't work. Overall, the audio from YouTube is still longer than that of our soundboard. I tried a few different ways, including using YouTube as the in point. For some reason, the soundboard audio is faster than the YouTube audio, and I'm unable to find a reason why or how to fix it.

I do thank you and greatly appreciate your trying to help.

You mean the audio is board's is longer although the content is the same, i.e., same in and out point on by content?

I suppose you could visually match the waveforms at some points and then time stretch (preserving pitch of course). I presume the YouTube audio is visually syncing with you video. You might have to do this in segments if the timing drifts over the course of the program.

The best way I can describe these drastic changes is if you removed too much reverb or noise reduction, and the affected parts now sound like they might be underwater. Warbly might be a good descriptive term, too.
