The echo suppression in SVN is shaping up quite nicely! I have also observed some - occasional, apparently data-dependent - misbehaviour in AGC. http://www.surfnonstop.com/~bandit/speex/echocard1/
I have now found a testcase where SVN AGC starts out good, but then it keeps increasing the gain but never decreasing it, and eventually goes out through the roof, during the same single recording. Observable in the last file in the just-added Example #6.

Did it also do that in 1.2-beta1? Jean-Marc
