Working Example 1: Left-ear absolute energetic difference ΔG in auditory gammatone filter bands between BRTFs resulting from the SOFiA (reference) and the SMATBIN filter processing (K = 2048 taps) for 360 head orientations in the horizontal plane (1 ∘ steps from 0 ∘ to 360 ∘) and a single broadband plane wave incident from the front (ϕ = 0 ∘,θ = 90 ∘) on a rigid sphere array with a Lebedev sampling scheme of order N=7. The gray lines show the difference for each individual head orientation, the blue line shows the difference averaged across all head orientations
