Yes this is for localization ---clicks are broadband, you need to identify which freq components are used. I still think humans can't discriminate the phase of a tone.
An interesting thing to try is to play with the "phase" button on many high-end gear. This supposedly matters for low frequencies, but despite my unarguably golden ears, I'm still not convinced I can hear the difference.
My Thiel speakers, however, claim to be "phase coherent", and that seems to be an entirely different matter. In other words, the different frequency components of a sound are transmitted in correct phase relationships (ie, true to the original sound), and the result is a (sometimes) astonishing level of spacial detail. Of course, non-audiophiles will poo-poo that claim, but even they will hear that the Thiels are far more accurate than the crap that's sold in Circuit City or whatever. So I figure I may as well believe Jim Thiel's claim that phase coherence is important in a speaker.

They can tell relative phase, but it takes a lot of training.

both. They spend a year training the cats, then a year or 2 collecting data, then brain stain, then vaporize. Each cat is worth about $1M when it's all done, and it's got a lot of skull missing while it's alive. But it's well protected with a lot of aluminum and epoxy :-)

I think you better keep it far away! And no, they don't play with higher order systems. The low level stuff is hard enough!!
