Sweeping the band - characterizing a room

[Phyl]

I've seen threads (can't find 'em now - doh!) where people have put a speaker and a microphone in a room they are trying to characterize.

They use some sort of tone generator to sweep through the audible frequency band, record the tones through the microphone, and then plot the response of the room. I guess you could call it spectral analaysis.

I'm not sure I've accurately described the process, but if anyone knows what I'm referring to, let me now what sort of tools (hardware/software) are necessary to generate the tones and perform the analysis.

Thanks!

Looks like using 'spectral analysis' as a search string works pretty well too.

This is going to be so cool.

I wrote THIS article last year for Electronic Musician magazine, and it describes the process using a DAW program.
