This is a "red herring."
At the basic level all you need is your iPhone with internal mic (the videos of audio recordings from which you are happy with), and the $4.99 RTA Real Time Analyzer which you download onto your iPhone from the Apple app store.
So in approximately 1 minute, and for exactly $4.99, you can have the "equipment to do so."
You are interested in the frequency response measurements of my system, which I appreciate. Why aren't you interested in the frequency response measurements of your own system?
I do not know about a red herring. Rex asked me a simple question. I should have just said "No, I do not have such measurements of my room." and left it at that not mentioning gear. You have wanted me to measure for months now. Wynona Ryder is famous for saying, "It is nice to want".
I am not really that interested in your FR measurements. I am more interested in the sound from the videos. That I can hear. Yes, measurements do show objectively what is happening. The lack of correlation between your measurements and your videos, to me is somewhat curious. There was a lot of discussion and I was surprised at the sharp HF rolloff, much lower that I would have guessed from the videos. I am curious to see if the measurements change and how with your new treatments. I hear a difference in the videos.
I do not really know why I am not interested in the measurements of my system. I like the sound as it is, and I would rather just listen to music and optimize the set up based on listening. Unlike your big flexible room, my room does not offer much possibilities when it comes to audiophile acoustic room treatments. I had them and learned how they changed the sound. At some point, I might get around to making measurements. Who knows?
I am curious to know why you seem so interested in my room measurements. Do you encourage Micro, Keith, and Al, or Madfloyd to measure their rooms? You have told me that you think my system has that "center of gravity", between 100-1K that you covet and believe is where the music is.
