Higher-order Spatial Impulse Response Rendering (HO-SIRR) is a rendering method, which can synthesise output loudspeaker array room impulse responses (RIRs) using input spherical harmonic (Ambisonic/B-Format) RIRs of arbitrary order. The method makes assumptions regarding the composition of the sound-field and extracts spatial parameters over time, which allows it to map the input to the output in an adaptive and more informed manner; when compared to linear methods such as Ambisonics.
The idea is that you then convolve a monophonic source with this loudspeaker array RIR, and it will be reproduced and exhibit the spatial characteristics of the captured space.
