Freq to rgb
i’m looking for a simple way to convert a number, representing a frequency, into a list of three numbers, respectively Red Green Blue channel, respecting the correspondances between the audio and the light spectra. I’ve tried with some simple algos but whitout good results.

Depends on what you mean by good results. You may already be doing this…
If frequency is a single number you can fiddle with it in various ways:
This is a basic problem of mapping sound to image and vice versa. A nice
You might also try fiddle~ and its cousins to collect spectral data from

there are a few good ideas documented from about 1700-something to today,

there is a work group of the AFIM wich works on the Visualisation of sound
I think you will be interested in their work…
Have a good time

thank you very much for the precious infos!
E.g.: an higher freq should be positioned in the range of the Blue-Violet if not standing at the synesthetic feels that probably wants to put an higher frequency within the Red range..and so on…
Anyway the link about visualization of sounds shows an amazing project! I have ever been interested in this kind of synesthetic correspondances, from Skrjabin (a semi-scientific approach) and Kandinsky (a total artistic approach to sounds’ visualization) to the contemporary goals on this ground as the mentioned O’Really videos on the Point Line Cloud’s Curtist Roads DVD.
Hope you can understand my bad bad english!

if you only want to map freq to color you can try this (just copy and paste it into a new patcher) :
#P window setfont “Sans Serif” 9.;
this is an adaptation of a little patch I made for the automatic determination of color.
maybe it’s what you need…
PS : don’t worry about your english, mine is not so good too…

thank you Antoine! This is exactly the scaling equation i need!
