Can anyone recommend a good software audio spectrum analyser to run under
WinXP?

RightMark Audio Analyser. It's free and does a lot more than just spectrum
analysis. Great piece of software

Free if poss, I'll pay a bit if necessary, but I'm not interested in paying
hundreds. Main application is for adjusting speaker EQ using pink-noise and
a measurement microphone.

RMAA will do that. If you look at the link below, you can see the sort of
analysis I did on my listening room and pickup cartridge frequency
responses.

Got a decent anechoic chamber? Because you are wasting your time if
you haven't. You also need some specialized software that will
integrate the response over a selection of angles - a simple on-axis
measurement wont do it.

In other words, this is one of the hardest jobs for an experienced
speaker designer and essentially impossible for the amateur.

I'm not trying to design speakers, I'm trying to set up align "B-chain"
response in an auditorium.

Ah, that is different. I would still do that by ear with music, since
response flatness is low on the list of stuff to get right. Sorting
out coverage, levels and delays is the big job. You need an arsenal of
recorded clips of various kinds - percussive, melodic etc to do that.

Noise and an FFT are very good for finding specific room problems,
though, particularly of the moding kind. I guess for this job you need
a real time moving FFT that will sit and give you a display of what is
happening right now - not a still snapshot of what happened a while
ago. Don't know if Rightmark does that, I quite like this

The site is Russian, but the software is in English and works well.

I've used RMAA to set the house speaker equalization, and it works.

When you are setting over-all response in a large room, remember that you
*don't* want flat response, you want a smooth curve for which there is no
exact mathematical justification for.

Check the Dolby site for "X-curve" for more info about that.
