Export = MultiCore - Export w/AudioSnap = SingleCore

If I export a multi-track project to .wav in Sonar, I see all 6 of my CPU cores working and the export is reasonably quick.

If I have AudioSnap enabled on some tracks on that same project and export, I see only one core heavily loaded and the export takes 30 to 40 minutes.

I could understand this if I had AudioSnap enabled on just one track and so all the work was occurring on a single thread.  But if I have multiple AudioSnap enabled tracks, why is all the work happening serially in one thread only?

I know what you guys are going to tell me - I should be bouncing the AudioSnap tracks first.  Sorry, no.  I don't make destructive edits if I can avoid it.  Export should just work properly with AudioSnap.  If I have a number of tracks with A/S, why doesn't each track get its own thread?

Thanks for the answer Noel, at least I now know the reason.

I guess it's not possible for multiple instances of the Izotope algorithm to run simultaneously huh?  No worries, I look forward to seeing this in a patch or a new version one day.

Possible in theory. In practice this is a third party library so we'd have to test it to make sure there aren't concurrency issues. It is on our todo list.

what i've done in the past when i used audio snap is bounce the snapped clip to a new track and then mute the audio snapped track.  i have to test it on x2 to see if it works the same.
