Matthew, I really appreciate you taking the time to look into this. I didn't know about DIRAC before reading your post so I did some research. I'm afraid DIRAC is a little out of my budget, but building a bunch of quadratic diffusers is (plus it will give me some much needed shop time now that...

What would I see in a waterfall graph if I had just one speaker and a mic, floating in an infinitely large room? Assume that those are the only things you need to make a measurement so no computer, no mic stand, no cable, no nothing; just empty space, the sound source and the mic. My...

@Matthew J Poes interesting read, thanks for the link.

So I went back and re-did the measurement this time with only one 256K sweep like @John Mulcahy suggested. While I was there I got curious and re-did the same exact measurement with no params changed other than the sweep length. To my surprise what I found was that the longer the sweep the...

Thanks everyone for the prompt reply. OK, will do that. And should I be using one or two speakers when playing the sweep? I didn't know that, thanks. Is there another graph (using this same measurement technique) that will accurately display the lower frequencies?

I finally got around to doing a measurement with the miniDSP UMIK-1 calibrated USB mic last november. I followed the steps described in the original manufacturer's website to the letter. And this is what I got (see attached REW ".mdat" file for more details). The mic position is exactly where...
