Pitch differences caused by shifts are not purely fine-structure based

Evidence

However, most of the time, when a harmonic complex tone and a shifted complex tone with the same envelope frequency conduct to a different pitch percept, the pitch percept is supposed to be elicited by fine structure only and to be independent of envelope. This can appear as trivial but the aim of this study is simply to convince the reader that this assumption is not true. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4613
