Ambisonics
The Ambisonics preset allows you to decode multi-channel
sources which have been encoded in Ambisonics B format.
Ambisonics B format contains four independent channels of
information to give a three-axis representation of the sound at
the recording position. The signals are: mono sound pressure,
left-right velocity component, front-back velocity component,
and up-down velocity component.
The Ambisonics preset uses the subwoofer configuration
specified for Music presets.
