I always keep the audio as the last thing I tweak in the project.
For one thing, audio volume is cululative, so there’s no sense in adjusting audio on one track if there might be additional audio at the same time.
If I am mixing audio from multiple tracks and later decide that the mix volume is too high or low, I will adjust that from either the master audio track (B key toggles it on and off the interface), or send them to a bus.
I also apply the Track Compressor set to ‘Limit Levels to -6db’ at the track or project level (or both).
