Note: Preceding examples show 1/3-octave smoothed curves. The smoothing of frequency response curve is done in different way than smoothing of spectrum magnitude. The ARTA uses approach to first interpolate and average frequency response on log-frequency axis, then makes smoothing by convolving that response with response of bandpass 6-pole Butterworth filter. |

I'm interested in whether there is a standard for smoothing acoustical responses, because I have noticed that 1/3 octave smoothing differs from program to program. |
