I think the imaging idea only applies to photons. Hence why blurei players use a blue laser. It has a shorter wavelength and thus can "see" smaller bumps on the discs. However, in the case of sound I suspect it has more to do with the idea that the wavelengths are very long relative to the distance between our ears. So much so that there is not sufficient difference in the signal received by each ear in order to localize it.
