Melodyne Version 1
Melodyne’s is a capable multi-track audio recorder, editor and mixer. In the Arrangement window, you can load in (or record) up to 24 vocal or instrumental tracks, edit these, then mix them together and export as individual sound files or as combinations of tracks. Editing tools let you shift a track in time, alter the tempo of the arrangement, or cut-&-paste between tracks. You can match the tempo of one track to another, or you can copy a vocal onto several tracks and edit the pitches of these to create harmonies The melodies can then be saved as MIDI files to view in a notation program or transfer to a sequencer. Melodyne automatically determines the pitch, rhythm and tempo of audio files. When I tried this, the results were good, but not perfect – so some manual editing was required, using the Melody Definition window. Melodyne’s Mixer window lets you select track inputs and outputs, and set levels and pans. Several popular file formats are supported, so you can transfer tracks to and from Pro Tools, or whatever. Melodyne can either use the Apple Sound Manager or ASIO sound drivers with audio hardware.
Melodyne is expensive – but it can work miracles. The processed-audio sounds very good, but sadly, there is no Undo function. I also encountered several unexpected crashes using version 1.0. However, nothing else available allows this level of editing – so for professional audio-editors and remixers it’s the only choice.
