Hey mate,
I never got the responce for this problem but figure it out myself!
I exported it and it made crackely sounds here and there, it was a wedding i was editing so its defenitly no option to even think about trying to blend it in, after i even tried to export to a DVD and it still did the same(just to make sure it wasnt my sound card options).
So i tried something (which worked for me), which was lower the sound on the actual timeline, because i had so many little clips everywhere and from 2 diferent camers the sounds were diferent and when i adjusted the sound i was on a clip from the worse camera out of the 2 so obviously the sound wasnt as good and had to turn it up and made the clips from my (good camera lol) too high, i did adjust the sound and it came out just right but what i did was listen to a song on Media player and adjusted the speakers sound to how i thought it was the right volume, then just switched over to APP and adjusted the sound on all clips by adjusting each one to the volume setting.
Off cource that was just a home made quick solution there may be many more and much better ones and APP probably could do something in less than half the time i took but i did what i thought was best to my knowledge, hope it helps...
Im more than happy to help, anymore problems just say
