exporting creating cracks and pops

[SlowTurtle]

Hi! I am a beginner producer creating music out of my bedroom! Whenever I try to export my song I'm working on, it makes pops and cracks in the exported file, but when I go back to the multitrack and listen, there's nothing there. I have tried creating different tracks for just the cracking sections, which has fixed some of the problems, but not all of them. And the cracks and pops aren't happening when a clip ends, it's happening in the middle of the clip too. I think I've narrowed it down to the automatic pitch correcter making the pops, but sometimes I play it back, and they disappear.

I have spent so long researching and trying to troubleshoot this, so ANY help would be apprecieated! 

I'm seriously at my wits end

Thank you so much!

You shouldn't ever try to do anything like automatic pitch correction during a mixdown!

The trick with anything like this is to pre-render your tracks. This applies all of the processing to the track before the mixdown, and means two things in your case; firstly that you've unloaded a load of intensive processing from the mix (which is almost certainly why it glitches) and secondly, you get to hear the results before you finally commit to it. What you are looking for is the little lightning bolt:

These occur in several places (as indicated) and can get you out of a load of trouble. What's even better is that if you change your mind about something you've pre-rendered, that's not an issue - you can undo the pre-render, make changes and then pre-render it again.

Sorry I should have said, all my vocal tracks are prerendered already!

Ok by the grace of God I have got them all down to just one crack. I rendered all of the tracks with effects, not just the vocals that were popping/had automatic pitch correction on them, and that fixed all but one of them!! Thank you!
