Ambisonics was first introduced in the 1970s as a way to record and reproduce spatial audio using 4 audio channels, denoted as first-order Ambisonics (FOA) [5, 85– 87]. Around the late 1990s, the higher-order Ambisonics (HOA) technology, using a spherical harmonics formulation, emerged [6, 8, 9]. FOA and …

Ambisonic content can be created in two basic ways: by recording a sound with a suitable first- or higher-order microphone, or by taking separate monophonic sources and panning them to the desired positions. Content can also be manipulated while it is in B-format.
