Well, I did finally buy a MiniDSP mic. It came in today and I fiddled with taking measurements. Mostly just testing 2 channel full range and seeing what differences I would find with the various Audyssey settings. I'm not sure I've taken measurements that are worth examination for much more than my curiosity. I didn't set everything to a 'reference level' volume for instance. I did follow a few guides I watched on Youtube and from over at the Audio Science Forum for basic setup.
Now, my Audyssey should be setup currently to only correct below 800mhz. What initially sort of baffled me was how much different 'Reference' and 'Flat' were at the top end in particular. In just a little closer review it looks like the Dynamic EQ is responsible for a pretty significant bump to 'Flat' at the top end. 'Reference' and the 'Pure Direct' mode have a almost identical top end with Dynamic EQ turned off and that is probably what I expected to see with Audyssey set to only correct below 800mhz.
I don't mind throwing a few of these up if anyone cares to look at what I've taken so far. It doesn't look like anything to brag about to my eyes. There's a gigantic dip at 110mhz that Audyssey has a hard time trying to smooth out.
I have frankly taken up listening in Pure Direct mode much more recently. I finally noticed that Audyssey is converting my SACD disc DSD files to PCM 48mhz? Something like that - it was from an article on here that discusses it. I still use it with almost anything 16/44. It can get a bit bright with some material, but now I see that is probably the Dynamic EQ that is doing it.
I'll continue to research how to do this better. Take multiple samples around the listening position, etc. I was mostly just playing around with the various DSP settings I already use.
I merged Right and Left channels for these. I suppose to diagnose specific room acoustic treatment needs it would require separate R/L measurements and I did take those, but I thought it was interesting to see what was happening with and without Audyssey and the various tweaks within it.
I did do a few with the sub, but I was mostly curious about my full range 2 channel for now. I'm sure this will be handy to see how my sub is performing in my room too.
I measured 10hz to 22khz. Not sure I'm doing it 'right.'
