Thanks a lot, I'll have a look at that.

No problem there, I always publish my stuff under the GPL anyway.

We've already done a fairly extensive web search for literature and 
links (mostly focused on automatic transcription, though), but I still 
have to work through that. I'll make the results available if they turn 
out to be useful.

It looks like Prony has been superseded by recent developments (last 10 
years or so) which offer better efficiency and numerical stability.

BTW, as you're from Finland, maybe you know Anssi Klapuri from Tampere 
University? He's been working on automatic transcription a while ago.
