Sound sample[edit]

Sound sample is not accurate. As a piano-note sequence, using notes of complex timbre and amplitude envelope, it does not comply with the description, "The tones are sine waves of constant amplitude, and switch between high and low four times a second, with no amplitude drops at the transitions" from the text.

I still get some illusion from the sample as supplied, but have no way of knowing what illusion I might get from the true waveforms. —Preceding unsigned comment added by 10:15, 17 April 2009 (talk)
