Bounce either too quiet or crackles
So, for context, here's the Logic file via Google Drive, if anyone wants to see: https://drive.google.com/file/d/1qdq4N0z1Vpq32jjYVUXaFBLodLQlqthZ/view?usp=sharing
I'm fairly new to all this, so terminologies and jargon might be a bit lost on me. In essence, I'm trying to create a loud and triumphant cinematic piece. Many tracks, orchestral, quite loud most of the way through. This is the first time I've made a song with this many tracks and instruments, but if I take too many away then the piece starts to lose its fullness and 'oomph'.
Whenever I play it back in Logic, it sounds fine. It sounded fine even before I tried adding compressors to every track and creating a slow decrease in volume in the master output, to see if that would help balance out the volume as the track gets louder throughout. My CPU seems fine. Adding an adaptive limiter to the master output makes it noticeably crackly during in-app playback, albeit not as crackly as the 2nd thing below:
Whenever I try to bounce the hecking thing, one of two things happen:
1) It's far too quiet when I normalise or "overload protect only".
2) When I turn normalise off, it's certainly loud enough, but very crackly and gainy.
I have no idea why Logic isn't simply able to take what I hear during in-app playback and put it into MP3 and WAV form, but it's not, and I don't know what's wrong.
Help pls.
