I try to simulate the "journey" of a sound in an ambient that changes its state, from solid (ice) to liquid (water) to gas (air).
I'd like to build a filter in PD (for real-time performance) that simulates solid-ambient (a sound that travels through a solid) and that simulates liquid-ambient (a sound that travels through water).
Is there any patch or part-of-patch that can help me?
Thanks

hi adrjork,

its sounds like a formant filter, you can use this abs from the DIY set of patch (a great set by the way). Look in the subpatch (pd workings) to have some exemple of formants for specific materials (metal, glass, plastic ...)

you might need to find some physical articles that describe sounds in those materials and find the right formants and adapt the patch or build specific presets.

Have fun

Wow... Thanks thanks thanks! I'll try this patch.

amazingly simple, yet amazngly good.

If Hardoff should see this (and for any other knowledgeable people) How does one go about finding the frequencies of materials (or chambers) they wish to emulate?)

Well,

it's not my doing, it's obiwannabe's and hardoff's ... (that explains a lot about the quality)

you can look up obi's tutorial with very interesting info on materials and their "sounding" :
http://obiwannabe.co.uk/tutorials/html/tutorial_tea.html

a table is presented :

Colour Range Sounds like

Violet 15-30KHz Gas escaping, angry snake
Blue 7-15KHz Light breeze, aerosol, hihats
Green 3kHz-7KHz Bacon frying, acid on concrete
Yellow 1kHz-3KHz Rain, distant waterfall
Orange 500Hz-1KHz River, city ambience
Red 250Hz-500Hz Airplane cabin, train/car interior
Brown 50Hz-250Hz Thunder, distant plane/rocket, large objets moving
Black 0-50Hz Explosion rumble, near infrasonic, sub bass.

Fioj... DIY2 is absolutely great! Thanks hardoff! It solves my problem.
