Now here is a question... does anyone have software that will take a 2D
image and convert it to a wave file??

Really just an inverse cosine transform (all data is real)... Would be an
interesting thing to play with, hmmm probably a way to have phase represent
color.. ( think I have a dimensionality problem, or dementia)...

as I'm diving deeper and deeper into Pd and externals, I'm willing to do
some video works. One of my aims is to create a spectrum analyzer,
preferably with pdp and pidip, as I have just compiled those without any
problems. Now, that I'm reading about the different objects, I don't
have a clue how to accomplish that. Is there an easy online tutorial
available? Or did anyone do that already and is willing to share his/her
patch with a newby?

My aim is to get something like http://www.bastwood.com/aphex.php but I
guess, that will be in five years or so ;)
