Let's see, the eardrums on a human head are about 5 inches apart, or
.42 foot apart.  
The speed of sound in air is about 1116 ft/sec.  
Speed = Wavelength * Frequency, so
Frequency = Speed/Wavelength
Thus, a wavelength of 5 inches (.42 foot) has a frequency of about
2,657 hz (1116/.42 = 2657).

A person with normal binaural hearing can certainly tell where a tone
of less than 2,657 hz (i.e. longer than .42 feet) is located in a
stereo field, or 3 dimentional space, so I don't understand how you can
assert 'if the waveform is longer than your ears are apart, you can't
tell where it is in a stereo field'.  Maybe I misunderstand your
statement?
