I think the technology in this patent rocks:
http://www.freepatentsonline.com/5012518.html
In 1978, this guy compressed speech to the most important 4 formants
(poles), plus a second order correction polynomial. It's based on the
same technology I've been playing with, LPC. He even does what I
wanted to do, making traces of formant movement over time. The patent
has expired, which means I can duplicate as much of this work as I
like for free. Even better, the patent includes an Apendix A, which
is the entire Fortran source code for the algorithm. I see no
copyright notice on the code.
So, am I actually allowed to copy the Fortran code directly? Doesn't
putting it in a patent application with no copyright notice place it
into the public domain? Too bad we don't have blind lawyers on the
list!
