You might want to take a look at some of the graphical sound systems, then. For example Pd (www.pure-data.org) is very easy to set up and yet very powerful. You could use some of the Pd extensions to create images of sound or the other way around. GEM is very easy to get started with, if you have an OpenGL enabled card. For reading from a TV card (or webcam) PDP is nice. > I don't have any idea how I can do this. > > What language, what libraries, and I don't have any Idea how work /dev/dsp. > What the first step? > > This project is for pupils of school where I work. This is directly programming the soundcard hardware. Do you really want to do that? In my opinion this could be too difficult for your pupils, if they don't have a certain background with that. But I may be wrong. Anyway, using something like Pd will still be a good experience, because you get to see the whole picture of sound generation better. The Pd author Miller S. Puckette also uses Pd to teach sound synthesis and such.

Or I can do this just with knowlegde about programer. I think, you will need some mathematics, but nothing too complicated. A bit of trigonometry is very useful in computer sound but you can get far with knowing just muliplication and summing. At least in Pd, that is. ciao -- Frank Barknecht _ ______footils.org__
