Shifted complex tone pitch depends on envelope-fine-structure interaction, not fine structure alone.

Evidence

First, this evidence that any perceptual effect that is empirically evidenced between harmonic complex tones and shifted complex tones should not been interpreted as a pure effect of fine structure. In fact, the pitch evoked by a shifted complex is based on interaction cues between envelope and fine structure (TE × TSFperiod ). Using these signals to tease apart temporal envelope cues from temporal fine structure cues is then a conceptual error. This impaired the conclusion that the pitch of unresolved complex tones is based only on fine structure information. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4659

• XREF: Connects to classic psychoacoustic literature on pitch of unresolved harmonics and the envelope/fine-structure dissociation debate (Moore, Oxenham).
• QUESTION: Worth chasing how the TE × TSF multiplication interaction term is formally defined — the notation is introduced without derivation.
