Pitch and rhythm paradoxes: Comments on ‘‘Auditory paradox based on fractal waveform’’ [J. Acoust. Soc. Am. 79, 186–189 (1986)] Available to Purchase

Schroeder [J. Acoust. Soc. Am. 79, 186–189 (1986)] describes the paradox of acoustic waveforms that sound lower when reproduced at higher speeds. The author has also demonstrated this paradox [J. C. Risset, J. Acoust. Soc. Am. 46, 88 (A) (1969); see also Seventh ICA, Budapest, S10, 613–616 (1971)]; in addition he has recently synthesized a rhythmic analog of the paradox, namely rhythmical sequences that can sound slower when reproduced at higher speeds.
