What are we using for room analysis? I have more than one reason for asking this question, the first being that I'm curious to hear what others use (mic, how they interface with the computer and how they compensate for known variances in equipment response), how much it helped their system and how they used the results in making their listening area(s) better. Another reason is that I'm in the position of needing a setup of this type because I no longer have access to the Audio Control RTA that I had used in the past. While it worked, I was never really all that geeked about some aspects of that model.
Price Range
I would also like to separate the setups into three groups. First, is the low cost but effective <$400 range, next is $401 to $1000 range and at the top would be the $1001 to $2000 range. I'm less interested in anything more expensive because I'm less interested in equipment that's out of the price range of most people. I know some here can buy whatever they want but I don't want to hear about that.
Microphone
This may be one of the most contentious parts of this discussion, for good reason. However, if the mic is calibrated and the response is compensated for, it can be as accurate as most others. I don't see a sub $200 mic being flat to within 1dB, anyway.
RTA Software
I'd like to know what is being used for test signals and data input (are people using TruRTA, EQ Wizard, or whatever?).
Interface
I want to know what people are using to get the signal to the software, whether it's a USB interface (M-Audio, Tascam, Lexicon, etc) or whether you're using a soundcard.
Computer
While it's not going to influence the test results as much as the other parts of the system, I'd like to know what people are using, whether it's an old desktop PC they had laying around or a new hot-rodded model.
Which tests are being performed?
I'd like to know if you're doing waterfall plots, RT60, impulse, LF decay, Spectral decay, Energy-Time or keeping it more simple by doing only RTA.
Thanks for any & all responses.
