Delayed sounds arriving from different angles are perceived as spaciousness, not comb filtering

Evidence

Comb filtering is often thought to be involved in all delayed sounds. However, a delayed sound arriving from a different horizontal angle than the direct sound is perceived as spaciousness, not comb filtering. It adds to the information about the room. — , Toole, Floyd E - Sound reproduction-…, 729

Categorization

• DEFINE: Clarifies when delayed sounds count as comb filtering versus as spatial cues — angle matters, not just delay.
• XREF: connects to: Sitting near walls creates repetition-pitch coloration in perceived sound; Late-arriving room sound becomes omnidirectional and uniformly distributed; The first-arriving direct sound perceptually dominates despite carrying less energy (+10 more)
