Gario,
That is amazing work! This is exactly the kind of thing I was hoping to find on OCRemix. Audacity really did bring out the volume on my mix that I couldn't find on StudioOne. So with that, I attempted the same process on another piece with similar instruments and mixing. I don't want to get too off-topic or merge posts but I had some questions about what you did. So for one, if you see a large spike in audio only for a brief millisecond, is there an easier way of tracking the source down other than importing the mix with a suspect instrument muted to see if the spike is still there, and repeating this process until you find the culprit? Also, would it ever be beneficial to use both soft and hard limiting in between amplifications, or is it always cleaner to just choose one? I wasn't aware Audacity had these extra tools available, so this is a whole new world opened up for me. For that I'm deeply appreciative.
