| Description | I wonder if it would be possible to add spatial stereo output or wave rendering.
What i search for, is roughly spoken only a default micro delay for the minor panning side.
Maximum Delay would be 1/1595 sec from c/ear-dist. or 27 to 30 samples (44,1 to 48kHz) |

| Additional Information | C&P from Wiki:
"For determining the lateral input direction (left, front, right) the auditory system analyzes the following ear signal information:
Interaural time differences" [that is what i search for]
"Sound from the right side reaches the right ear earlier than the left ear. The auditory system evaluates interaural time differences from
Phase delays at low frequencies, group delays at high frequencies
Interaural level differences Sound from the right side has a higher level at the right ear than at the left ear" [that is standard panning]", because the head shadows the left ear. These level differences are highly frequency dependent and they increase with increasing frequency.
For frequencies below 800 Hz, mainly interaural time differences are evaluated (phase delays), for frequencies above 1600 Hz mainly interaural level differences are evaluated. Between 800 Hz and 1600 Hz there is a transition zone, where both mechanisms play a role.
Localization accuracy is 1 degree for sources in front of the listener and 15 degrees for sources to the sides.
For frequencies below 800 Hz, the dimensions of the head (ear distance 21.5 cm), are smaller than the half wavelength of the sound waves. So the auditory system can determine phase delays between both ears without confusion." |
