Pitch correction in Music

It is long known that popular singer's vocals are pitch corrected through software. I mean off-key notes are adjusted. Yes technology can do wonders!

Computer Software is changing the way musicians create, record, and manipulate music. Software called Music Objects Recognition (MOR) can dynamically adjust music elements like harmony, tempo, melody, etc. and can even emulate human performance on the piano..!

Dr. Andy Hildebrand, Inventor of Autotune

Andy Hildebrand, inventor of pitch correction software Auto-Tune, developed it by applying the data processing knowledge he gained from his work in geophysics, where acoustical waves are used to search for oil. Amazing isn't it..!

He estimates that 90% of popular music vocals go through Auto-Tune. Also hardware versions are used to pitch correct live performances on the fly.

Recently released “Throat and Harmony Engine” is capable of analyzing a person’s voice recording and recreating it.
