I'm trying to do the same thing currently using my RS SPL meter and the Spectra Plus RTA software. Here's a link to TerryC's page that has the Spectra Plus software link and a compensation file for the RS SPL meter as well: http://members.tripod.com/~terrycthe...um/page12.html
I only played with it for a short while last night, but I couldn't figure out how to actually get a frequency response analysis. Just using the RTA it looks like I have a HUGE (read ~20dB) dip between 64-70Hz. If anyone could give some tips on the Spectra Plus program, that'd be great.

You can use your same RS SPL meter with the PC software located at this website: www.etfacoustic.com
Additionally, this site explains the use of the software by providing a complete example demo room.
Good reading just to understand the principles and possibilities of room acoustic tuning.
