Thank you John. And thank you Pat for allowing us to view your excellent series of explanations and implementation. Although I believe this is targeted at the large installation market, I would assume the fundamental scientific principles used in this method can be applied to a home stereo...

Thanks John, I can see where I have erred. Great explaination, hope others see your response to this, great info.

Hi All, I am creating two filters and using the Trace arithmetic function combining them into one filter. My question is, how do I convert the combined filters now a single filter into a BiQuad file for use in my minidsp 2X4HD or SHD? I have no problem creating a single filter, then in the EQ...

Thanks Sam and SM52, really appreciate your help.

Hi All, I have read the REW help document and did a quick search here but...my question is.. Can REW measure the resonance produced by the ports of a ported speaker? The manufacturer (Tannoy) doesn't have any publicly available specifications. I believe I can measure my crossover frequencies...

Thank you John, "Magnitude averages do not have phase information and so do not have an impulse response." Ok, thats logical and understand how the software can only accurately calculate of real world knowns. The vector average includes phase and produces an impulse response, but it must be...

Thank you John, works a treat.

Hi All, Using V5 20.13 Phase alignment I am wishing to measure the distance between an impulse peak and 0 time. I tried to use the right click and Shift key (Apple) to measure the nano seconds but find REW has a message to contact REW. I have illustrated below with a screen shot. Is this only...

UPDATE I believe I have found my mistake to not be able to view Impulse curves by the incorrect display click box in the upper left hand screen area of the wave form display. Its not easy to see it. You have two drop down menu choices (%) or (dBFS), its % and then you can display it. I still...

Hi All, I am using V5 20.13 on a macbookpro Intel. I have no problem recording both left and right SPL frequency response graphs. The measurement records both SPL and Phase. When I then view the Impulse results I get a full display of information. I am wanting to rectify frequency alignment etc...

Thank you John. Appreciated and will search the website in more stringent detail in the future.

Afternoon all, I am measuring a speaker and have found on the "make a measurement menu" under sweep and settings that the number to repetitions per each sweep is greyed out and can not be used? I have used this excellent software for some time now and have never thought to do a number of sweeps...
