– Decodes to B-format via fixed matrix derived from capsule directivity (cardioid/omni).
gain_i = Σ_mn B_mn * Y_mn(l_i) with optional or basic energy preservation for in-phase rendering. 2.2. Microphone Array Processing Eigenmike (em32) → Ambisonics up to 3rd order: Uses pseudo-inverse of spherical harmonic matrix sampled at capsule positions.
– For loudspeakers at directions l_i :
B_mn(t) = s(t) * Y_mn(θ, φ) where Y_mn are real spherical harmonics (SN3D normalization).
