Are you familiar with the "Circle of fifths"? That's the first thing that came to mind when I saw your circle patterns, and it directly relates to "harmony".

- gbh444g 6y agoACF composes all harmonics together and that's what likely makes the images visually appealing. However ACF doesn't give special treatment to harmonics that are exactly N octaves apart, e.g. A4 and A7 notes.
- hashtagmarkup 6y agoWould ACF be better if did give special treatment to those harmonics? I understand they are an arbitrary distinction, but humans do seem to like them.
- gbh444g 6y agoIt would. The 12 notes are usually mapped to 12 colors, and ideally the sound image would reflect that. One "brute force" way to do that is to split the spectrum into 12 parts, draw 12 ACF images and then mix them. A less brute force approach is to tweak ACF to recognize that F-2F-4F-etc frequencies are specially related, even more specially than just F-2F-3F-4F-etc.
