Pan Pot uses standard amplitude panning (aka
pair-wise, stereo pair, etc).
UHJ creates a stereo-compatible two-channel
UHJ mix, which encodes some surround sound
information into stereo output that can be
decoded with a surround sound receiver.
Binaural applies HRTF filters to create a sense
of 3D space with headphones.

The reference delay value for ambisonic output. When
Channels is set to one of the Ambisonic formats, this
option enables NFC-HOA output with the specified
Reference Delay parameter. The specified value can then
be shared with an appropriate NFC-HOA decoder to
reproduce correct near-field effects. Keep in mind that
despite being designed for higher-order ambisonics, this
applies to first-order output all the same. When left unset,
normal output is created with no near-field simulation.
