Apples and oranges. I don't need word processing software to be open source to understand how it works. A proportedly novel compression algorithm is a different story...
I can be totally honest with you: FLAC being open source is more valuable to me than any performance benefit you could ever possibly offer over it. It only becomes interesting if I can actually read the code and see what you did.
I am genuinely interested in what you've done here, and I sincerely hope you publish it.
