[Speex-dev] Little question about the article "on Adjusting..."

I just checked with my code and the cross-correlation algorithm actually
used a learning rate of 0.25, not 0.2 (the Gansler algo was 0.2 though).
Thanks for pointing that out. I'll try to fix it before the article
shows up in IEEE Trans.
