Thanks, I hadn't seen the 3d spectrogram in snd. It does pretty much 
what I wanted to do. So I'll refocus and try to get it working in 
realtime first. It will probably take longer (because I have no idea 
about jack and the like), but I'll get it started.
Thanks for all the suggestions and the pointers from everyone, when I've 
made some progress I'll post.
