Fig. 7From: Comparative evaluation of interpolation methods for the directivity of musical instrumentsDistribution of the Mean Square Error MSE (top) and reconstruction time in s (bottom) for interpolation with the (zero phase) SH approach (left), the sign-retrieval algorithm SDR rgn+dbl, the spline method and the triangular technique (right). On each box, the center indicates the median, and the bottom and top edges of the box show the 25th and 75th percentiles, respectivelyBack to article page
