That Melodyne sounds so good and is so simple to use is based on two things. The less important is the technology.

The decisive factor is its understanding of the music.

Melodyne identifies the notes and the relationships between them. It is only as a result of this knowledge that Melodyne’s algorithms are able to “think” and operate in such a musical way. The benefits to you as a musician and producer include the famously superior sound of Melodyne and many other advantages that software lacking this understanding of musical contexts is incapable of offering.
