GM,
Yes, my first objective is just to measure the room and understand what I have to start with.
My first attempt with the RS meter in-room at my listening position and with the Stereophile disk 2 frequency sweep warble tones produced a frequency response curve for my front left and right that was + or - 3 db from 30Hz to 4Khz, then I have a frequency bump of +3db up to + 6db at 4kHz and 8kHz before going back to normal at 9kHz.
I also have what appear to be 2 room modes, a -5db null at 50Hz and a -6db null at 200Hz.
The reason I am comtemplating a PC software RTA, impulse and energy measuring system is not for absolute accuracy, but for the following reasons:
1) a graphical record of each change vs effect that I make
2) a close to real time display of changes/effects as I make them
3) a cost effective solution (only software, I will use RS meter mic)
4) MY TIME! Changes can be accomplished rather quickly vs. just a RS meter and a frequency sweep and my pencil and paper.
Currently trying to find anyone who has used the ETF5 software program, but nobody has responded in the affirmative yet.
What do you think?
