Should audio be kept in as few audio bounces as possible for FMOD? Does it save CPU and/or optimize the build in any capacity?  
For example: (Car Engine)  
Bounce all stages of RPM of an engine side by side, in one audio bounce, then separate them in FMOD?  
Or does it make no difference at all to just bounce out each stage of RPM as seperate files.

Thanks so much in advance

Hello,  
I would say the number of audio files you put into FMOD is irrelevant.  
So I would go with multiple files, just easier for me to handle - if you add an audio editor to your FMOD project (Like iZotope RX) you can edit a single file really quickly if needed without interfering with other events.
