T-Pain popularized the hard-straightened pitch, even going as far as releasing an iOS app called “I Am T-Pain.” It’s sounds incredible, leaving little to no artifacts on vocals recorded in a treated space, but are in need of a little fixing.īut Autotune isn’t reserved exclusively for pitch correction. In a hurry? I love Melodyne 4 Studio from Celemony. Whether you’re a home producer or work at a major recording studio, Autotune and other pitch correction software can help deal with a weak vocal performance.
