Günter Ehret even found it in the mouse: http://w1.570.telia.com/~u57011259/Ehret.htm One biological function of f0 pitch is in fact the support of sound localization. If two or more harmonics of a complex sound (vocalization) can be unified into one percept, pitch, they must come from one direction and from one sound source.
