Little question about the article "on Adjusting..."
Hello Jean-Marc Valin and all the speex-dev team,
I just read your article "On Adjsusting the learning Rate in Frequency
Domain Acho Cancellation With Double-Talk"
It is a very very interresting article, but I have a little questions
about the last section,
I understood that AEC with Gansler or cross-correlation algorithms have a
learning rate of 0.2 (in your experiment) or 0 if a double-talk is
detected.
But, in the figure 4, where you have plot the learning rate function of
the time, I can see that in the first 2 seconds, cross-correlation
algorithm's learning rate is about 0.22....
