Distribution of the relative changes in root mean square (RMS) in dB (top) and maximum values (bottom) when interpolating Gaussian input noise with the SH, spline, and triangular interpolation methods, for 1000 independent instances of a random input vector f. On each box, the center indicates the median, and the bottom and top edge of the box show the 25th and 75th percentiles, respectively
