AEC Patented ?
...nd all the Speex-dev team,
Today I have a little question about patents and the AEC.
I' am not a lawyer, but after a deep research in esp@cenet.com,
I found that in August 2003, an AEC called "Double talk insensitive NLMS
algorithm" (DNLMS) have been patented by Gary Q Jin, Gordon J Reesor, and
others (US 6.608.897 B1).
It uses a continuous adaptation step as speex, to avoid adaptatif filter
divergence during double-talk.
Is the computation method really the same as speex AEC (hope not) ?
Somebody who have a deep understanding of Speex AEC algorithm might have a
look at this patent...
