actionscript microcosmos

At last weeks FFK09 I once again visited Andre Michelle´s talk about generating and manipulating sound with Flash10, wich was, as always, very interesting. After that, I got this idea of how perlinNoise might tingle? Well, I´ve to mention that I´m totally 404 in this field but Andre kindly makes available some nice examples and sources such as Tone Wheels wich I picked as basis.

My focal idea was to build a perlinNoise map, convolve and work out the octaves and add some random moving particles on top. Now, whenever a particle hits a specified range of colours within the map, mainly at the octave peaks, a tone is created (each particle has a different timbre). Carefully spoken - we´re listening to the sounds of perlinNoise now and it sounds a bit fierce, I can tell you!

At the moment I provide two different perlinNoise maps wich can be shifted by mouseDown (look out, the second map is kinda cpu heavy weight!) and you can change the particles timbre by pressing the SPACE key.

So, turn on your speakers and listen to the sound of perlinNoise..

Launch

And for all those, who want to teach this kinda gloomy sounding perlinNoise that the world out there sounds even more cheerful, here are the sources. And please don´t rant about my sloppy code enhancements, due to the fact my harddisk crashed today and I´m more than lucky that I managed to publish this snippet at all!
