Hi all,
I'm developing a small app which uses aubio to extract the fundamental
Frequency of a monophonic guitarsignal to drive a set of wavetable
synths. It works quite well and I'll put up on the net when I have the
time.
But I would like to extract the fundamentals of a polyphonic signal.
Does anyone know of a lib which does this in realtime? Or at least a
state of the art paper I could implement?
thanx,
Gerald

Hello Gerald,
Can't help you with your question but reading your mail reminded me of
the LV2 pitchdetect plug-in:
https://github.com/Joeboy/joeboy-lv2-plugins
http://www.youtube.com/watch?v=unM7bd0GZ0Y
I don't know if your application is a bit similar but maybe the above
project could be helpful anyway.
Best,

Hi,
well essentially I'm doing the same thing just all in one app now. The
plan is to make an app with 4 Synth types, who's output will be
convolved with the input signal. That will make the sound of the guitar
sound more synth-like.

Hi Gerald,
I don't know the exact state of the art, but Nick Collins recently
used "Anssi Klapuri's great 2008 paper 'Multipitch analysis of
polyphonic music and speech signals using an auditory model'" to build
a polyphonic pitch tracker for SuperCollider.
Since Nicks' code is GPL, maybe you can even re-use it. See this
email: https://www.listarc.bham.ac.uk/lists/sc-users/msg10760.html

Looks interesting . I'll take a look at it.
Thanx,

Hi, has some got PolyPitch compiled on linux? It complaining that
SCWorld_Allocator is missing. I've installed SuperCollider 3.4 on ubuntu
oneiric.

Yes, i compiled PolyPitch and got it running (very cpu-heavy) some time
ago. FC14, 2.6.35 kernel and SC3-dev sources pulled from git january
18th. Only some minor tweaks to some header-files iirc to build it.
The missing SCWorld_Allocator might suggests your version of the
sc3-sources are not recent enough? Perhaps try with a sc3 source-tree
from more recent git.
