How do you feel about in-room MMM FR measurements? For in-room FR I get results that are consistent and repeatable and they seem to correlate well with what I hear.
For me the in-room measurements that I really struggle to get any kind of confidence in are "timing" measurements taken anywhere but near field.
I always verify with MMM first, instant repeatable results and reliable up to about 700Hz. It's the timing stuff for me that fluctuates and I'd forgotten the Umik1 messed that up but I'll go back to my XLR mic and focusrite next time I'm working on anything in the time domain.
Actually more powerful tools I have at my disposal re DRC/DSP more I am preferring to do as little corrections as possible. Better to under correct than over correct.
I agree completely, when I see tutorials that suggest you force 20-20Kh into a target I cringe feeling empathy for the poor fools trying to follow along a technically frustrating false path. If your room and speakers are ok to begin with just up to Schroeder and only peaks though going a step further with bass alignment is very beneficial.
The topic has strayed into measurements because all of these programs and methods we've been talking about in this thread have measurements in common. Basing any correction on bad data is only going to make things worse and waste time. As has been mentioned - garbage in, garbage out....
I'll start then, necessary bits:
- Measurement microphone - XLR with audio interface better than USB for clocking issues (Umik2 ok)
- Mic stand with boom
- Calibrate your sessions - loopback, always the same SPL in app and on gear
- Turn off ceiling fan, HVAC, fridge - If I leave my ceiling fan on I always have a huge anomaly at 110Hz, at least it's repeatable!
I'm probably missing stuff, what else do any of you do to set up for measurements? Off to digest that FSAF link now.
