This is my first post on GS so I am sorry if I break bro code or something haha.
I'm working on tuning my recording studio rooms better (Grandma's House Audio if you want to checkout some of my work ) And I've been doing TONS of research and I'm currently stuck in a rut... I don't know which omni mic to get to analyze my room!
A lot of people keep saying the ECM8000 is great as well as the dbx RTA-M. I can't really seem to find frequency response charts easily for omni's which I think is weird.
All I've found is that the high end on these mics don't respond as well. So would I be better off spending a couple more hundred bucks or will I be putting out mixes just as good if I use the ECM or whatever?
As mentioned almost any omni will do for analysis, however if you buy a slightly nicer one, you might also be able to use it for recording. Line Audio OM1 is a killer, I also like our Sennheiser K6 omnis. Oktava 012 omni would be another option. Also the modular 3 Zigma stuff looks amazing
The Dayton EMM6 and the MiniDsp UMIK-1 come with an individual Calibration File specific to that mic. These files make both close to scientifically flat when pointed directly at the source of interest.
EDIT +1 adamboon, the DPA4060 is an amazingly useful studio mic.
Even inexpensive omni condenser microphones are quite flat at bass frequencies - what separates the men from the boys is how high their response extends, and how flat they are above 1 KHz. We tested to only 20 KHz, though I imagine some of these microphones are useful to even higher frequencies.
... From this data it appears that for measuring loudspeaker setup and room treatments, the $40 Nady or $50 Behringer are quite adequate - within a few dB of the most expensive options - and far better than the Radio Shack SPL meter which is often recommended.
