Hey gang,
Recently I had the task to compute the pitch profile of a vocal track, so I thought I'd post the setup which I used.

WARNING!
The download includes a demo track of my own singing. The tool clearly demonstrates my inability to hit the right notes. (For the record: David Bowie scored even worse! (It didn't surprise me, I always thoght the guy could not sing. ))

In its current form, the schematic is merely a proof of concept. To make it a useful tool, it would need to include features like auditing, zooming in and out, playing selections, online monitoring, etc. I do not have the patience (read: skill ) to do this, but if someone else wants to have a go at it, have fun!

Wow!

This is all way over my head, but of course I see the similarity to Melodyne (and a couple other plugins) first. What they do additionally, is to slice the original audio, those slices are then rectangles drawn right over the pitch profile (vertical position based on average pitch in the slice). And then the magic happens, by moving those rectangles up or down the pitch is lowered or raised, by using the mousewheel the "pitch peaks" are compressed, etc.

Just saying this as a concept idea in case, somebody with more talent than me sees this and may be using this as the base for offline pitch correction.
