5.6.2 Vector Base Intensity (VBIP)

Vector Base Intensity Panning is a similar variation to the VBAP technique. It can also reproduce a 2D or 3D immersive sound field with sharply localised virtual sound sources.

How does it work?

VBIP was designed to improve on VBAP when calculating the high-frequency (above 700 hz) localisation criteria. The selection of which speakers to use to render a virtual sound source is very similar to VBAP, only the gain calculations differ.

The same 4 dependencies mentioned for VBAP, also apply to VBIP. You will need to listen for quite a nuanced difference between these two panning algorithms. Try to compare how each panning type handles the higher frequency content of your material.
