Here is a link and description of software that might do what you want from another board I frequent...
-------Room EQ Wizard (free measurement and parametric EQ setup software)
Hi All,Beta testing has been going well so I've made the latest version of my Room EQ Wizard software available for download from http://homepage.ntlworld.com/john.m...omeq/index.html
Room EQ Wizard is a Java application for measuring and correcting room resonances. It includes tools for generating test signals, measuring SPL and frequency responses and automatically adjusting the settings of parametric equalisers to cancel the effects of room modes. It was initially written to help with the setup of the parametric TMREQ filters on TAG McLaren Audio AV32RDP and AV192R, but the latest version also supports the BFD Pro parametric filters (with correct modelling of the effect of the bandwidth control, which is quite different to the description in the BFD manual ).
Measurement is stepped sine, with local loopback for soundcard response compensation and DFT to isolate the measurement frequency. Log swept sine measurement and impulse response extraction are on the dev list but some way off. The Wizard can also import measurements in the ETF export formats or from text files in a basic comma-delimited format - details are in the help files, which can be browsed online at the site and are included in the program.
The sig gen provides sine waves to 0.1Hz precision, sine sweeps (linear and logarithmic), square waves and various pink noise signals including "full" range (pink spectrum down to just below 10Hz), speaker cal, sub cal and custom filtered to suit your needs.
Note that the app requires V5.0 or later of Sun's Java Runtime Environment (JRE) to be installed, available from http://java.sun.com/j2se/downloads.html
Hope it proves useful.
Best regards,
