Re: two cycles
It does not (I think) specifically address this point, but the method
described in Gardner and Magnasco's paper "Sparse time-frequency
is offered as a possible explanation for the "remarkable acuity of
auditory perception". As a signal processing algorithm (that is,
mathematically), under the right conditions, the reassignment method can
give quite precise estimates of the frequencies of resolvable components
given only two fundamental periods.
Perhaps this paper is of interest?

Can anyone point me to literature which shows how the auditory system
performs the "two cycle" feat, or to papers which show how such a "two
cycle" feat might be acomplished mathematically or to any papers of a
more recent origin which discusses this ability.
