"William Sommer******"

The ear/brain system can be sensitive to inter-aural timing
differences down to a few microseconds...

What is your evidence for this? Above about 1kHz, the brain doesn't
recognize phase or timing differences.


** Huh ? That is rubbish.

Its above 1kHz that it all happens.

The ear has little or no sense of direction at low frequencies but is very
sensitive to higher frequency transients.

One can instantly recognise left, right, in front and even behind.
