Due to loudness normalization on streaming platforms,
the days of needing crazy loud mixes are thankfully over.
Dynamic is the new Loud!
Before the mastering session, I recommend removing anything doing a large amount of gain reduction (more than 4-6dB) on your main bus, especially ultra-maximizers like Waves L2/L3, FabFilter Pro-L, iZotope Ozone Limiter, etc.
If you like the flavor added by whatever mix bus processor/compressor/limiter you have, go ahead! However, I don’t recommend letting it do much more than 2 to 4dB of gain reduction.
A 6dB gain reduction is a change of -50% of the signals original amplitude.
