Russell! I think aliki might be your friend. GUI tool for getting imp8lse responses. It has the tone generator, a sine sweep, and I suspect some diagnostics. If not, there are other GUI-tools to work from there. Displaying frequency related diagrams. I think, that Fons has also written one or more analysing apps, but I don't know, if they do exactly that kind of analysis. I really know only of one, which is not really ment to do that, praat. It's meant for voice analysis. But I'm not really into graphical interfaces. You can get a simple version of it with songanalysis. Don't have the URL. It's a text-based program, that gives you relative strength of sound in 749Hz steps. Mel scale or so. It's a simple text-output with relative numbers. I don't really get their meaning. But you definitely get the gist of it all and you see harsh peaks or drops. Hope that helps a bit for a starter.
