What a free alternative needs
The capabilities that keep people paying for Melodyne.
Polyphonic note detection and editing
Separate the notes of a chord or guitar strum in a mixed recording and move each one on its own.
Note-level pitch, timing and formant editing
Graphical tools to fix drift, vibrato and timing per note, not only snap a voice to a scale.
DAW integration through ARA
Edit audio directly on the host's timeline without bouncing, following its tempo and tracks.
Multi-track editing
See and edit the notes of several tracks together to keep harmonies in tune with each other.
Why it is hard
Separating notes from polyphonic audio is research-grade signal processing, and a usable editor also needs low-artifact pitch and time resynthesis and ARA host support.
