Digital wow/flutter demodulation and analysis
http://audiamorous.blogspot.com/2009/02/so...wowflutter.html

Wherein I discuss the implementation of a quadrature demodulator and some preliminary wow/flutter results for several inputs.

A separate branch off the Knowzy sample analysis thread. This was going to be a post, but then it got big, so I blogged it.

So your tool is not going to be some compact easy-to-use stand alone program, but is tied into a number of other programs including Labview.

Well, tied into one  other program. Whose runtime is free.

I'm moving way too quickly in terms of hammering out needed features for this kind of stuff to justify settling down and writing a better UI or rewriting it in C++. I mean, I'm having doubts as to even how to plot this stuff - and don't even get me started on how many features I'm cramming into a single spectrum plot app.

This sort of tool needs to eventually get out to lay audiophiles at low or free cost to make a lasting contribution to the field. I get that. For that to happen obviously it needs to be streamlined, particularly in the UI. But doing that prematurely is simply not optimal.

Wow, that is big and about 90% is over my head!  I have some serious studying to do before I can take it all in.

It looks like you have the start of a really useful tool that doesn't exist in the community and that's very admirable.
