Demonstration of fractal temporal deviations in a simple drum recording. A professional drummer (inset) was recorded tapping with one hand on a drum synchronizing with a metronome at 180 beats per minute (A). An excerpt of the recorded audio signal is shown over the beat index n. The beats detected at times Sn (green lines) are compared with the metronome timing Mn (red dashed lines). (B) The deviations dn = Sn—Mn fluctuate around a mean of -16.4 ms, i.e. on average the subject slightly anticipates the ensuing metronome clicks. Inset: Read More
