This post is a natural extension of that idea. I've been thinking how to introduce colors into ACF images. ACF splits a waveform into a set of pure cosine waves and aligns them together by removing the phase. The idea is to color each cosine wave with the note it corresponds to, so when these waves are aligned, not only the amplitudes of the waves add up, but also their colors.
Confused since pitch and frequency in my mind are the same thing. I googled around and there is precious little about this that I could find to enlighten me ... uses a pair of FFT's or some such.
A noir, E blanc, I rouge, U vert, O bleu : voyelles,
Je dirai quelque jour vos naissances latentes :
A, noir corset velu des mouches éclatantes
Qui bombinent autour des puanteurs cruelles,
Golfes d’ombre ; E, candeurs des vapeurs et des tentes,
Lances des glaciers fiers, rois blancs, frissons d’ombelles ;
I, pourpres, sang craché, rire des lèvres belles
Dans la colère ou les ivresses pénitentes ;
U, cycles, vibrements divins des mers virides,
Paix des pâtis semés d’animaux, paix des rides
Que l’alchimie imprime aux grands fronts studieux ;
O, suprême Clairon plein des strideurs étranges,
Silences traversés des Mondes et des Anges :
— O l’Oméga, rayon violet de Ses Yeux !
But you’re right, it also looks like an alien alphabet. Very cool
