just about the same topic. You can find the archive here:
In particular, Sampo Syreeni wrote:
"But perhaps the most shocking discovery here is that with sufficiently
large test sets, 180 degree phase differences can be distinguished at a
statistically significant level, monaurally only. That I think was what
lead to the periodicity/rectifier models of pitch perception in the
first place, long before e.g. missing fundamental kind of phenomena were
propertly attributed to the nonlinearity of the cochlear cilia."
