Hey gang,
before I go reinventing somebody else's wheel... has anybody written
something that takes a (sound) frequency in Hz or MIDI note and outputs
the transposed color in RGB values? Along these lines:
F#44 = 737 nm(Infrared)
G 44 = 696 nm(Red)
G#44 = 657 nm(Red)
A 44 = 620 nm(Red-Orange)
A#44 = 585 nm(Yellow)
B 44 = 552 nm(Green)
C 45 = 521 nm(Green)
C#45 = 492 nm(Green-Blue)
D 45 = 464 nm(Blue)
D#45 = 438 nm(Violet)
E 45 = 414 nm(Violet)
F 45 = 390 nm(Ultraviolet)
Or even something that takes the light wavelength in nanometers and
gives separate RGB values? I'm working on a simple color organ for a
friend this week.

Have fun..
