audio to midi realtime patch - possible & feasible with m4l?

[elt.net]

@elt: works nicely, thx, dont forget to install fftw3.dll to max folder if anybody want to test this on windows

As I'm not at all a PC user, I don't know what is this file, sorry.
Where to find it ?
Where to add it ?
What does it do ?

Thx.

edited my post, link there, windows version of pitch~ needs this as stated on tristans jehans homepage, kind of fft algorithm, dont know why this extern compared to the mac pitch version...

Ok. thx.
I don't know how to had this file. I'll just notice this on the description...

@pasha

here is a preset i optimized several times to my voice to trigger a osc like with audio to midi

http://www.mediafire.com/?2v47xix7dvja82r

Tune & Vol of the osc is modulated by pitchtrack and transient in the osc control window. For live use i dont like this too much, as zebrify peaks with small feedback permanently. It seems this have to be setup best for individual voice, feedback noise, mic type, similar to other audio-to-midi plugins. Im also unsure what zebrify really does here, but as in my preset tune & vol is modulation controlled, there has to be some discretisized data which the pitch tracker creates, also u can range the highest and lowest note.

Ur 1) example looks a bit weird to me, but im not deep in zebra, dont know exakt diff. between xmf and vcf. But if u want to trigger a synth with ur voice would u do it my way or do i overlook here something. Would be great if u simply can load a zebra synth preset in zebrify and then modulate all 4 routing lines by pitchtrack & transient. Seems now i would have to make all synth presets again from scratch.

Let me try to explain. Signal is split in two lanes: a)Guitar sound goes into XMF. That's a cross modulation filter. b)Guitar sound goes into another lane through a VCF (Formant filter type) and rejoined with a) via the XMF sidechain.
Cross Modulation Filters represent a way of doing a sort of what Operator does. You have one carrier on lane a) and one modulator on lane b). Is actually the same sound but being passed through different filters, it gathers different harmonics characteristics. So when one is used as the carrier (natural sound) and the other (VCF Formant Filter) as the modulator interesting effects are shown. XMF stays on lane a, after a shaper to boost signal. Lane b is muted. XMF accepts lane b as sidechain after VCF. So the XMF cutoff filter depends on lane b. To make things spicy you can have a comb filter after the shaper and split the sound after the comb. A brassy sound awaits there!
No MIDI is involved here. Pure on the fly audio manipulation. However, the envelope follower and key follower depends on MIDI pitch, that's why is monophonic. Zebrify converts Audio to MIDI anyway note by note and you can use Key Followers and Envelope Followers to modify the sound or parameters inside XMF.

I'll post something as soon as I can. In the meantime, take a look here:
