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.

align "B-chain" response in an auditorium.

First thing to remember in auditorium sound is that you *don't* want flat
response.

What's a "B-chain"? I feel stupid asking this question, but google sheds no
light.

Also, if there's a B-chain, then there is an A-chain. Wazzat?

Is there a C-chain?
