Shifted complex tones cannot isolate pure temporal fine structure effects in pitch
Evidence
These stimulations have a double interest. 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…, 4613
