AUTO TUNED? - ITZY “CAKE” M/V @ITZY 

All those K-pop, and J-pop groups are autotuned or pitch corrected, even this very good 8 girl Pinoy pop group, who actually do their own singing live. But they can really sing. Here's a video from January 2022 of the group rehearsing, dancing and singing a cappella in front of a mirrored wall. They are really accurate and have very good harmonies while doing their routine. There's no way this could be pitch corrected, as far as I know, as it's all one microphone picking it up, and it doesn't seem to be pitch corrected. Maybe you could analyze this. You don't even have to remove any music. The best singer of the group is Maloi, the girl with the black short pants and black knee wrappings, who is also the lead singer, I think. ‘Kahit Na’ Mirrored Dance Practice With Live Acapella Vocals | #BINI ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WZcTczAL78I.html
