order MIMO impulse response
§If only spherical harmonics of order 0 and 1
are taken into account, a complete spatial transfer function measurement
requires
16 impulse responses:
16 impulse responses:
§Once these 16 IRs have been measured, it is
possible to compute the
response of the room with a source and a receiver having arbitrary directivity patterns, given by the
O-format source functions {rw, rx, ry, rz}, and the B-format receiver functions {rw, rx, ry, rz}:
§In which also each of {s} and {r} are sets of 4
impulse responses, representing
the frequency-dependent directivities of the source and of the receiver
