– For a plane wave from direction (θ, φ) with signal s(t) :

| Order | Channels | Encoding Example (SH coefficients) | |-------|----------|-------------------------------------| | 0 (Omni) | 1 | W | | 1 | 4 | W, X, Y, Z | | 2 | 9 | + channels R, S, T, U, V | | 3 | 16 | Higher order | ears audio toolkit

– Decodes to B-format via fixed matrix derived from capsule directivity (cardioid/omni). – For a plane wave from direction (θ,

– Allows user to define arbitrary sphere/plane arrays and compute encoding matrix. 2.3. Binaural Rendering Core pipeline: Ambisonic signal → SH-domain rotation → SH-to-binaural filter bank → Headphone output. ears audio toolkit
