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 will look your suggestions. Very thanks!
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
Hummm... directly soundcard hardware??!!! :(
I will test your suggestions, but... I just wanna one program can show one image when
pupil play one C note ,or G, etc and maybe control intensity of color with gain of sound.
Something that it can select colors, pictures and texts using pure notes played with
guitar or harmonic or other instrument. Is not to produce images but to *select* images or
colors (images too) or text.
Is it programming direclty in soundcard hardware? Not exist some librariy done can make
this job (send to my program one pure value represent the note played)? I don't want
Midi sound, it is very horrible to hear :)
I know, I want much. But to our project is very interesting give for pupil the possibily
to choose the relation note/color/picture or note/word.
Is it very hard? For me all in this audio-world is hard because I don't have much
notion about hardware programming (I'm just one database specialist), but if it's
possible just using done values sent of the one library, all is ok.
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. See his upcoming book at
http://www.crca.ucsd.edu/~msp/techniques.htm I'd be glad to hear about your experiences.
:) You will hear my screams!!
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
So... very very very thanks for your atention.

Ah, no, I misunderstood you, when you were talking about /dev/dsp.
/dev/dsp is very near to the soundcard. You don't play music
on it, you play ones and zeroes.
What you want to do, does not require this low level. I would really
recommend Pd (and using the "fiddle" external), or something like
jMax, Spiral Synth Modular or similar.
Is it very hard? For me all in this audio-world is
hard because I
don't have much notion about hardware programming (I'm just one

I'd recommend to look for something high level instead. Like jMax or
Pd, but I'm repeating myself. ;)
ciao
