In layman’s terms, if a direct sound reaches our ears anywhere up to 00 ms
before the subsequent refl ections, we can determine the position of a sound.
For example, if you were facing the central position of the mix, any sound leaving
the left speaker would be delayed in reaching the right ear and vice versa
for the left ear, an effect known as interaural time delay (ITD). Considering that
sound travels at approximately 000 m/s, this effect can be emulated by setting
up a delay unit on a mono signal and delaying it by a couple of milliseconds,
producing the impression that the sound has been panned.
