...alongside the mic signal (green). You can see the delay is in the order of 1000 samples. That's way too much to do anything useful because the tail doesn't even "see" the echo. You need to reduce that delay if you want the AEC to work. See the manual.

...SOLA) 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.

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.

Dear all, i am currently evaluating which codec to be used for a "very narrowband" voice communication system (using either VoIP either GSM CSD) on mobile devices running Windows Mobile and Symbian OS. I had experience in using AMR-NB 4.75 with VAD on Symbian OS and all worked very well. However, AMR it's not royalty free and if i need to use it on Windows Mobile i will need
