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 yet 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.
Frank, I am curious, when you say lab work, what type of acoustical environment and measurement distance are we talking about? DTR? How loud are the reflections/reverb relative to the direct energy arrival. What frequencies are we talking about? 100 Hz? 1k? 10k? What size time windows are you using? Not trying to hassle you - I guess I am just asking because you are needing a psuedo-anechoic measurement - just trying to get an idea of the measurement conditions that are requiring it.
Also, feel free to contact me offline at Rational Acoustics and I can get you a copy of v6 to see if that has what you are looking for. As I said/implied, this is a feature that will eventually get activated in v7, it is just low on the priority list right now.
wahoo,
