A single neural autocorrelator may handle both pitch and localization

Evidence

It is tempting to think we have a built-in neural autocorrelator, which is used both for pitch perception and for source localization by time delay. — Eric J. Heller, Why You Hear What You Hear- An…, 1936

Categorization

• QUESTION: Does one neural mechanism really serve both pitch audition and spatial localization? This unifies two perceptual systems under one computational theory.
• XREF: Connects to autocorrelation theory of pitch from chapter 23, and to HRIR/head-related transfer approaches in spatial audio (e.g., HRTF-based virtual reality sound).
