Is there a different mapping of FFT information to a two dimensional image that would make harmonic relationships more obvious?
IE, use a polar coordinate system where angle 12 oclock is 440hz, and the 12 chromatic notes would be mapped to the angle of the hours. Maybe red pixel intensity is bit mapped to octave, IE first, third and eight octave: 0b10100001.
Time would be represented by radius. Unfortunately the space wouldn't wrap nicely like if there was a native image format for representing donuts.
- crubier 4y agoYou need the mapping to be only to 1 dimension, since you need the 2nd dimension for time
