Dear João Paulo Feliciano - hope you are feeling fine! The Ipomea Tricolor
we have showed at the expanded of the experimenta 2003 was controlled by a
Lanbox LCX and Max/MSP! I do work with Max+ since years now to realize my
installations and I would be glad to provide informations if possible and
desired.

We have developed the Ipomea Tricolor as a space for relaxation and
meditation - but it is in general an ideal space for experimenting with the
synergie of light and sound. We do have a big (5.5*3.7 m) amorphic textile
space illuminated with +- 1100 LEDs (1Watt Luxeons (RGB)) with a six channel
(circular) soundsystem (+subwoofer) integrated. The light and soundsystem is
controlled with Max/MSP (and the LCX) - in this way everything is possible
(;

We would like to provide the Ipomea Tricolor to sound and/or light artists
for composing, programming their own generative or fixed pieces for this
immersive environment.
If someone is interested and wants to visit the Ipomea Tricolor please get
in contact offlist. We do have an exhibition space in Berlin/Germany. See
the signature below.

There are some more Max/MSP/Jitter externals which are quite usefull to
soundanalysis, and usefull examples for the use in sound to light mapping,
too.

Tristan Jehan has released the analyzer~:
"FFT-Based Perceptual Analysis
Outputs Pitch, Loudness, Brightness, Noisiness and Bark scale"

On Tristan Jehans page you can download the externals - the analyzer~
includes different functionality provided by single externals like pitch~
and bark~ etc developed by him, too. There is a breat tracker beta version,
too

There is the centroid~ external by Ted Apel, Puterbaugh, and D. Zicarelli.:
"Compute the spectral centroid of a signal. centroid~ computes the spectral
centroid from fft~ input. The spectral centroid is a measure of the spectral
average weighted by amplitude." - sadley no OS X version...

The example /examples/jitter-examples/audio/jit.poke~-spectogram.pat shows
how to write the amplitude values of the spectral bands to a Jitter window.
You can grab this values to map the amplitudes to (dmx)colors directly, or
after calcutations to find centroids etc.

The example /examples/jitter-examples/audio/jit.peek~-osctrack.pat shows how
to use the "jit.3m" external to get the min, max and mean of the rgb values
of a movie.

In the end of /JitterReference/jit.cellblock.html you will find a picture.
Here you can see how the Jitter externals jit.matrix, jit.unpack, and
jit.cellblock are used to get and display the rgb values of every single
pixel in a movie (matrix data) seperatly.

"suckah" is nice, too. You can "feed in any screen coordinate to get the rgb
values of that pixel".
