Thank you Teodur! Actually, there is no autotune there. Instead they use a program called Melodyne and alike which does not "kill" the voice like autotune does (in pop music for example) but just align it where a note is not hit perfectly while preserving all the dynamics of a human singer. These are the standards of today's production and everybody use it without exception.
Anyways, I'm happy you loved it! Thank you for your kind words and stay tuned! :rolleyes:
