Awesome John! That's what I was missing. I ran some mic scans and I am getting good, consistent measurements now. Wow, what a difference! Thank you very much!

Matthew, I will try to explain better. John, yes, I mean soundcard calibration. I can apply a window to the result, but I am unclear if applying a window to the result is changing the cal file operation of zeroing out the base system and therefore subsequent scans are more accurate scans of the...

Ok, thank you for the infomation on windowing. I figured it out how to see the IR and adjust a window on a scan. It helped, but one issue that I see is that when I make a reference cal scan with a reference mic, I am unable to apply a window on the reference scan. Therefore, when I scan with a...

Thanks Matthew! I will definately look into windowing. I have no idea how to do that yet. Outdoor scanning is problematic for me. Here are some programs I found that are supposed to do quasi anechoic response: OpenTDS, a free program on Github, written in the Juice Framework. I haven't figured...

I would like to obtain a frequency response scan of a speaker that excludes room reflections as if the speaker was in an anechoic chamber. I would like to know if REW can do these types of scans using some kind of impulse response analysis or time delay spectrometry techniques. I am trying to...
