Melodyne is able to change the musical parameters of voices or instruments without any actual influence on the character of the recording. Melodyne extracts the pitch and the rhythm, and provides an area in which to play with the audio material. Any change in this material is interpreted by the software in a musically intelligent manner and the result will always sound natural. Working with Melodyne is as easy as editing notes with MIDI.

Pitch shifting and formant correction by more than an octave are performed without affecting sound character and velocity. New melodies can be invented with a given material and unpleasant intonations can be corrected with a mouse click.

A change in intonation is possible by an increase or decrease in phrasing or vibrato. A change in formant is produced by an amplification or diminution of the resonance volume, thus making a trombone out of a trumpet sound or a tenor out of a soprano voice.

Flexible time-stretching allows the acceleration or deceleration of a single note or of a whole arrangement through the concept of local sound. There are no limits to deceleration, and a standing sound will be the ultimate result when velocity is zero.

Melodyne recognizes the rhythm of music, as each given note "knows" its place within a beat. Notes can thus be quantified automatically, and they can also be synchronized to a reference melody with a mouse click.
Via copy and paste, a new melody can be derived from single notes or a new arrangement can be created from single tracks. Differences in beat will be corrected automatically.

Melodyne can handle up to 24 tracks in real time.
