Hi Abe,
I've just commited all you code (revision 10572).
But _caution_: not as it was in the patch. We can now take
advantage  of clam plugins and keep your code separated from the
main library. Afterwards we can decide to merge it into clam libs.

So do a svn up, change dir to CLAM/plugins/speech
and do scons (will ask for clam_prefix and prefix options)
then export CLAM_PLUGIN_PATH=. or absolute path to plugins/speech/
and start NetworkEditor (../../../NetworkEditor/NetworkEditor)
You'll realise that FormantExtractor appears on the CLAM Plugins
category.

In order to keep you changes separated I had to copy and rename the 
following classes:
  - AbeLPC_Autocorrelation
  - AbeLPModel
Eventually, after more review we'll merge them with those files in 
CLAM.

Actually this experiment-on-renamed-files could be considered a
general development pattern. The important thing here is never have
duplicated class names or file names.

I tried to run the example, but jackd kicks NE out. Does it works
for you? Have you tried with jack?

Cheers!
