Here are the placements for some of the Panner Mode presets:
ORTF (With Surrounds)
Amplitude varies due to the directionality of the microphones, while time
delay is varied based on the distances between the microphones (which
each feed a speaker).
AB (With Surrounds)
Because all of the microphones are omni-directional, the amplitude is the
same for all of them, but the delay differs due to the distances between the
microphones.
Sphere
The Sphere setting is based on a microphone as shown in the picture
above. Amplitude, phase and frequency response is calculated based on
measured signals from such a microphone.
