Dear List, It recently came to my mind that nearly all experiences of pitch are related to animal communication soounds. Sure, there is something like edge pitch of broadband stimuli, maybe even echo pitch under specific conditions, but clearly periodic sounds stemming from a periodically moving source would nearly always come from an animal (and most often be communication sounds... exception: humming of bees etc.). Is this a complete nonsense? Or could it be that pitch processing evolved in parallel to communication capabilities? Best, Christian Kaernbach
