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
However, in an attempt to recreate Deficere2's style, Venkyra21 has used Melodyne to make his Adolf Hitler - DADDY (Parody of PSY's DADDY) DPMV. This resulted in a bandwagon effect where many Untergangers used this program for DPMVs entered into the Hitler Tunes DPMV Contest. (Venkyra21's parody being one of them)
