I need to do a project using sound, and for that I thought changing colours (and maybe textures) according voice sound and diferente the pitch of the the voice... how can I do it using Max7? Can someone help me? Thanks

Maybe a good start is to use the fzero~ - object to analyse the incoming voices from the microphone. Next step is to transfer the frequency domain (the fundamental frequencies for female voices is from 165 to 255 Hz, the male one is from 85 to 180 Hz) to the colour domain (0 up to 255) and you are done ;) Easy way here is to use the scale - Object.

I attached a quick patch to demonstrate a panels backgroundcolor - change by analysing the pitch and amplitude of a synth - signal. Parameters to adjust are definitley the repeated use of the frequency - value resulting from fzero~ to build up the RGBA - colorlist and the constantly use of the "1." as the value for the alpha - channel. Happy patching!
