I suppose the first step would be to get an FFT filter up and running,
seeing as it is essentially a set of bandpass filters.
From what I understand is you measure the requisite frequency bands and
follow the change over time, applying those changes to the filter bank.
I imagine a single arbitrary filter /might/ work.
You'll start with pretty much an unhindered signal, then the signal's
filtering should follow the bands of the input voice. You'll need
something with lots of harmonics to get it to work properly, though.
Some like a sawtooth or square wave. It'll be a while before I get an
implementation, so you very well may beat me to it ;) I have tons of
other stuff, real life, rebuilding a system that I had for years, etc..
to get in the way.
