To encode the A-format into the B-format we create an Ambisonics channel in our DAW. Then, we insert dearVR AMBI MICRO into the first slot to encode the signals coming from the capsules (A-format) into the Ambisonics B-format.
Within dearVR AMBI MICRO, we select “A-Format (AMBEO)” in the input section and “B-format FOA” in the output section. While the A-format consists of the four capsules, the four B-format channels are named W, X, Y, and Z. These four channels represent a microphone with a dedicated polar pattern, each of which is pointed in a specific direction. Channel W represents an omnidirectional microphone that records sound coming from all directions. Channels X, Y, and Z are figure-8 microphones that point in different directions. All combined channels represent a 360° sound field.
