[Speex-dev] AEC algorithm explained

[Jean-Marc Valin]

Hi everyone,

I thought this would be of interest to some people interested in the
details of the echo canceller. My paper describing the double-talk
algorithm was finally accepted, so I have now put it on my website. You
can get it at: http://people.xiph.org/~jm/papers/valin_taslp2006.pdf

Happy reading,

	Jean-Marc

P.S. If you're only interested in *using* the echo canceller, don't
bother.
