Please note the following sorely neglected article, which shows that when one hears a twelve-component uniform-amplitude harmonic complex in cosine phase in which a single component has been shifted out of cosine phase, the singular component segregates from the complex. At the same time, however, the pitch of the fundamental does not seem to be affected. The article also shows that if one passes the waveform of such a complex through a square-root or cubic-root compressive transformation, the spectrum of the resulting waveform has a peak at the frequency of the singular component.
