Before I get around to posting measurements, here’s a quick breakdown of the equipment that I am measuring with. It’s nothing too fancy, but it seems to do a pretty good job:
Behringer ECM8000 mic
M-Audio MobilePre as both the mic pre-amp and the soundcard
Dell Inspiron D600 laptop on battery power
ETF 5.98x software
RadioShack SPL meter for setting the SPL calibration level in ETF
I have some additional software installed to play with like the free Room EQ Wizard and trial versions of various programs to try out (TruRTA, Spectra Plus, etc.).
I highly recommend the Room EQ Wizard if you have a soundcard with a stereo line-in (many notebooks only have a ‘mic’ in and not a stereo line in) and want to measure your in-room response. It’s an excellent program and can be used with just a Radio Shack SPL meter as the mic.
