windowing

Hi, I'm trying to use REW to do some quasi-anechoic measurements. With ARTA and HolmImpulse the gating is straightforward. However, on REW I can't figure out what to do. In IR windows, there is left window, window ref time, and right window. I simply want to apply a 5.5ms gate. If I put 0...

I'm interested in understanding more about the various types of IR Windowing, and how/why they should be used. i.e. Tukey, Blackman, etc... The instructions just mention how to change the default settings, but don't say anything about what the different types of windowing do. Are there any...

Dear John: Many thanks for your continued advancements in performance in REW! If I understand correctly reading the latest beta notes, you have conquered the OSX measurement issues with Java that plagued us before and led me to use ASIO on PC? -------------- I'd like to make my "annual"...

Hi I uses windowing centered on the first arrival pulse of the signal for the IR window settings when I fine tune the phase matching at crossover position between two drivers. In practice, I do not use the windowed SPL graph to see the XO frequency crossover point because of the influence of...

I was hoping to open up a discussion amongst you EE types to expound upon the advantages and disadvantages in different windows in different situations. Would anyone be kind enough to explain this in light of frequency response, THD and IMD measurements, burst measurements, and CSD? John K had...

I know that measuring for speaker response indoors is probably folly but I thought I''d give it a go since I was all set up from dialing in the active Xover up for my DIY 3 way boxes .... The three drivers were measured with the omni Dayton about one inch on axis. The cyan color trace was...

John, Is there are way in REW to change the default window markers of -125ms and 500ms? Ideally you would be able to set these in the ini file to whatever value you needed. And once you change them in use, REW would remember the new values for consecutivie measurements during that session. It...
