...ic is not synched to the speaker (I used different sound device). The mic is running about 0.06% faster than the speaker (that's about one 20ms frame drift every 3.2s or so). But I don't think it matters again, because first I have drift handling in my library (similar to how PLC work, with WSOLA) to compensate this, and secondly it doesn't seem to affect the beta3 EC anyway. But just in case it matters. And last, the test was done on Win XP. Thanks Benny [1] https://trac.pjsip.org/repos/browser/pjproject/trunk/pjsip-apps/src/samples/aectest.c Jean-Marc > > Benny Prij...

Hi Jean-Marc, I tried with both testecho and my test program, and for some reason it just doesn't cancel any echoes with the 1.2-rc1. The testecho from beta3 binaries works fine, and also if I replaced mdf.c in 1.2-rc1 with mdf.c from beta3 and use my test program, it will work again. This happens for both 8KHz and 16KHz. Any ideas? I could upload the test samples and results if needed.
