If I load a limiter into the master section, obviously I cannot change settings on a per-clip basis. All of the songs would have to have the exact same limiter settings.
If I load the final limiter into every single clip, and I dither within the limiter plugin to 16-bit, I can set limiters differently for every song. My question though: If I do this, is the signal path completely transparent from this point all the way to the final master section output? This way, I can trust there will be no artifacts added or anything after final limiting within clip fx?
