[QUOTE="Jamie Anderson, post: 58631, member: 1135"] Re: Pseudo-anechoic (windowed impulse) measurement on Smaart Ahh yes, phase. We did plot the phase info for the "Time-Windowed Transfer Function" measurement in previous versions of Smaart (v5 & v6) - and that capability was coded into the v7 TF engines, but the feature has not [I][B]yet[/B][/I] been added to v7's Real-Time mode. However, I would say that, given the time windows used for the MTW process, and its averaging & smoothing algorithms, I haven't needed a pseudo-anechoic measurement to get a stable, accurate phase traces in lab conditions - or even under reasonable room conditions.
