Melodyne Uno is the ideal tool for editing audio as if it were MIDI. Any melody can be easily edited - you can change the pitch, tempo, phrasing, formants and timing of monophonic audio files in a direct and uncomplicated manner. Unlike other programs that stretch pitch or tempo, Melodyne works to make sure that your music still sounds musical when it is done by preserving the original phrasing (including the vibrato) when performing corrections in pitch.
