ANY SOUND YOU CAN IMAGINE... this title of a book is very much my approach to sound and music.
Please join me on myspace! : http://www.myspace.com/eye_and_ear_control - there's not much there yet but
I'm working on it.

I'm using Puredata both for my own projects and teaching. These are some projects that I'm working on.

November 2009 - Vocode with Shebby


A model of the classic vocoder where the modulator is passing through a series (64 in this case) of very narrow bandwidth filters in order to analyze the harmonic content of the incoming sound. Different from the classic model the resulting level-per-bandwidth information does not pass onto a carrier sound but rather they define the levels of an additive chebychev oscillator (read Wikipedia about Chebychev polynomials). It only requires to define a fundamental of the oscillator.
The polyphonic version (here with 3 voices, the right hand for simple pianists) doesn't have a good speech comprehension as the monophonic version that I'm more interested in (for my guitar patches). Here's the patch to download - please note that it requires Pd-extended.
If you are interested in the monophonic version please mail me.

PLAYING WITH INTEGER HARMONIC

An older patch - I was quite amazed by the possibilities of the chebychev oscillator - here's my first experimentation with it. There are just 8 harmonics that constantly fade in and out at different levels with a little but of reverb on it. The patch is here (requires Pd-extended).
