Mathematical Calculations Find frequency of the lightwave and then map it to sound frequency Use these values in conjuction with the RGB values from the image Use: r = 2*3.14*(fsr/FS)*(t+1); g = 2*3.14*(fsg/FS)*(t+1);

Unformatted text preview: b = 2*3.14*(fsb/FS)*(t+1); output = ((red*10000)*sinf(r*t))+ ((green*10000)*sinf(g*t))+ ((blue*10000)*sinf(b*t)); Audio Output The audio is outputted from the formul iChannel0LeftOut = indivOutput; iChannel0RightOut = indivOutput; Issues Can not compute an entire 64x64 image at once, there is a delay causing a popping sound Final product only analyzes one pixel, but could maybe be expanded to an entire picture if given more time...
