Tom: Thanks for your observations on pitch shift. I'm curious why a shape change of the external auditory canal should be implicated. Does this effect only apply to broadband signals, such that changing the canal's resonant frequency might give a "formant" change in the spectral shape? I can't see how it could change the pitch of a pure tone, unless the basilar membrane is also deformed somehow. .
