Auditory illusion with exponentially-spaced frequencies

I’m sure someone has researched this auditory illusion but it’s new to me. All of the sinewaves have a fixed frequency, but that isn’t what you hear. I’m sure it’s related to the way that linearly-spaced frequencies add up to an impulse. ( a = { // Exponentially-spaced steps // 300, 300 * 1.00277, 300 * (1.00277^2), 300 * (1.00277^3) etc. var sig = SinOsc.ar((4 ** Array.series(200, 0, 0.002)) * 300).sum; (sig * 0.02).dup }.play; ) a.free; [auditory-illusion] hjh
