I have been using 1/48 smoothing filter in my Preferences. Should I use another smoothing filter like 1/6 instead ? What is the impact on using 1/6 vs 1/48 besides smoothing out the measured curve ? Tks

I am pretty sure that smoothing/averaging setting only affects the display, not the measurements.

I think the rule of thumb is to use very little or no smoothing for the low frequency graphs and heavier (1/6 or even 1/3) smoothing for full range graphs.

Ethan Winer of Real Traps recommends setting smoothing at 1/24 for LF and 1/3 for MF and HF range graphs

Can the smoothing filters be applied after measurements?

Zheka has it right: No smoothing for low-freq graphs, 1/6 or 1/3 for full range. Due to comb filtering caused by reflections, most rooms deliver a “ragged” graph for the upper frequencies. Smoothing allows you to see the underlying trend in frequency response.

Wayne , you are right , the high freq graphs are raggedly without the smoothing filters. BTW when running the Sub curves should I leave the LPF of LFE at 120hz ? Would this setting would impact sub measurements in stereo mode ?
