About me, Norm Spier:

I am a mostly-retired free-lance mathematical statistician and computer programmer (with an interest in music and music-related engineering), living in Northampton, Massachusetts, U.S.

Some of what I've been doing over recent years has been programming software related to the science of music and sound, both for my own edification, and for the possibility of applications. I've realized that some of the software that I've written may be of use or interest to others, and so, when such software is reasonably convertible to be used by general users, and not encumbered by complicated license agreements (e.g. VST plug-ins), I have usually stuck it up on the internet on this site.
