oh sorry lol I found the mastered vocals on yt. sorry to dissapoint you lol, but I actually am very good at mixing and mastering acapellas, but I don't got the isotope machine thingie unfortunately. rodrigo has a ton of great juice acapellas on his channel, that's where I found them. I belive he got the raw acapellas from the studio juice goes to (enviyon), and he somehow accessed the compters or asked the engineers for it
