visual sound waveshello, I need some advice to develop a sound wave "simulator". these are the references http://matzsoft.com/Animated.html http://www.johnholland.ws/images/books/soundwaves-big.jpg basically i'd like to obtain a grayscale image which would simulate the propagation of waves bouncing on the borders, possibly having multiple wave sources interfering with each other. it would be like having different drops on a flat water surface. i saw something similar in jitter some years ago but can't find it anymore.. :( is there something similar in qc? I had a look around kineme and thought that as a first step I could try to create a greyscale image from the output structure that _1024_WaveGenerator but I can't figure out how.. any hint? something similar asked before.. rgba values to pixels. http://kineme.net/forum/Discussion/General/ImagefromStructure thanks for your help. best, giorgio

To me it looks more like water ripples than sound waves. Give a try to the CIripples, it might get you started.
Merci François, yes ripples :) let's say waves more than sound waves..
But unfortunately in my library I have CIShapedWaterRipple and Ripple but both deform an input image (I'd like to have a greyscale image just with the waves instead) and they seem not to be continuous..
More than a filter I'd need a generator I guess..
This a combination of Particle System & rendering to a GLSL Grid and Billboard, both set to Over, a Noise GLSL shader with texture input. Based in no small part upon Rideout's Noise GLSL and a simple GLSL with texture [conjoined together].
Just make some noise :-)
Wow! Cybero that's a really smart way of utilizing the particle system.
Cheers :-).
I think the conjoined GLSL shader is the best part, though the Ripple Particle System makes for a very effective simple peak levels visualizer & one can always change the inital image employed.
Could do with exploiting some 3D Transform of that initial Particle System.
