Autocorrelation predicts pitch yet met lukewarm reception
Evidence
The residue pitch formula estimates the time of maxima in the autocorrelation function, and therefore the corresponding pitch frequency. We can change which peak is being estimated by adjusting the Ni. However, this does not say which pitch dominates in marquee effect cases (see the following). — Eric J.

Broader Connections
- Qualitative pitch mirrors the qualitative nature of autocorrelation peaks
#expands(0.85) - The auditory system performs pitch analysis as autocorrelation per sub-band, summed into a correlogram.
#expands(0.85) - Echoed sounds spaced 1-10 ms generate a perceived pitch of 100-1000 Hz
#exemplifies(0.85) - Autocorrelation models explain pitch and can separate concurrent vowel sounds differing in fundamental frequency
#exemplifies(0.80) — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1658 - No neural evidence supports autocorrelation models of pitch at the brainstem
#contradicts(0.80) — Dijk, Pim van, Physiology, Psychoacoustics and…, 4494 - Pitch maps to repetition frequency but is not a simple physical property.
#corroborates(0.80) - Higher partials dominate pitch because their sharper autocorrelation peaks win
#expands(0.75) — Eric J. Heller, Why You Hear What You Hear- An…, 2094 - Pitch can be perceived even when no partial exists at that frequency
#exemplifies(0.75) — Eric J. Heller, Why You Hear What You Hear- An…, 2031 - Listeners reconstruct a perceived pitch that is not physically present
