Working Example 2: Left-ear BRIRs/BRTFs resulting from the SOFiA (reference) and the SMATBIN filter processing (K = 2048 taps) for frontal head orientation (ϕ = 0 ∘,θ = 90 ∘) and impulse responses of a classroom for three different rigid sphere arrays with Lebedev sampling schemes of orders N={1,7,35}. For better illustration, the absolute amplitudes of the SOFiA BRIRs in the left column are inverted and the magnitudes of the BRTFs in the middle column are 1/6-octave smoothed. The right column shows the magnitude differences between the SOFiA and the SMATBIN BRTFs
