Melodyne

Celemony Melodyne is an audio pitch modification tool developed by Celemony Software GmbH. Like the infamous Auto-Tune by Antares Audio Technologies, Melodyne is used for correcting or deliberately alter or distort vocal tracks from a song.

The tool has been used by a large number of professional record producers, namely Coldplay, Thomas Newman and several others, to tune and manipulate audio signals, typically a singer's vocals.

Use in Downfall Parodies
Among Untergangers, only Deficere2 is known to have used Melodyne for his musical parodies, altering Hitler's pitch in tune to the music.
