Hello guys I'm a newbie here! I want to record a vocal track in Garageband (came free with my macbook), but I don't know what effect to use to get a certain sound I want. I'll give you an example: Boyfriend (Official Single) - Justin Bieber - YouTube Starting from 0:37, how does he make it so it sounds like that? I know it's not reverb. But what effect can I use in Garageband that gives that "double voice" effect? Thank you very much for reading and hopefully I can get some help!
