@d-healey Exactly...it is exactly as you said...this is the only way to have a louder result using saturation(of course very carefuly...we dont want much saturation)...the higher peaks of the sound will be altered on a tranparent way (not as compression acts) so we will have finaly in the middle area (and this is the real acoustic area that is perceived by human ears) clearly more volume.
For example you listen to the same track that is mixed by 2 different but lets say good producers
The one of them used no compression and no saturation and made a good mix
The other made the same good mix but used a combination of saturation and compression but not only globally on the Master channel (imagine that every different track needs different approatch)
Finally we have 2 finished tracks both play at 0db but the second is about 6 dbs louder (i am talking now as a producer that i have seen that hundrends of times)...
Final conlusion...if you will not saturate or compress or the better of the 2 worlds both you will never be loud enough as the other senario...
If you dont care about the volume it's perfectly ok
If you care it is one way.
