FWIW I don't use those tools. I export the mix down as a wav file, bring it into Audacity, then normalize to -3.0dB. I probably could do it in Studio One Pro 7 but I like to listen to the song on another program. There have been a few times that I had to go back into my DAW, remix, then listen in Audacity. Then in Audacity you could export the song as a MP3 or any other file format you want.

This is an old habit that I got use to and see no reason to change. YMMV

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.
