A half-wave-rectified-threshold spike model encodes both envelope and fine structure in one mechanism.

Evidence

Second, when thinking about pitch perception of unresolved complex tones in terms of interaction between envelope and fine structure, it appears that the limitation of phase locking is probably much less critical than when thinking in terms of fine structure only. In fact, it seems clear that there is no need to encode every phases of the signal to encode the most intense phases located nearby an envelope maximum. This explains that the simulation can extract a periodicity related to pitch when the carrier frequency is over 10 kHz (Fig. 3 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 4660 (#qualifies, via linked claim)
