Hi all, does anybody has ran echocancellation successfully on windows ? I have a problem playing audio there. If you play a wav file no mater how I play it after comparing the captured data with the original file there is always difference in the audio length (for 18 sec of audio there is more than 250 ms of difference). Which of course breaks echocancellation. I've tried playing the audio through mmsystem, directsound also using portaudio lib. The only way of playing audio correctly was using audacity binary version for windows. I've also tried compiling audacity from source and plying with it - and again the problem persists. I've also determined that with audacity binary version that if the sound is too load, I've put the volume on max value this problem occurs again. Any ideas? Can you point me of working solution I can look at ? Thanks damencho

I have no direct experience with it, but it seems to me like MS has managed to make sound on Windows suck even more than it does on Linux, which I consider quite an achievement.
Hi, I'm integrating speex echocancellation using it through JNI in sip-communicator. I have successfully done it on linux but now I'm testing it on windows and have this problems and I'm trying to solve it. damencho Jean-Marc Valin wrote:>> does anybody has ran echocancellation successfully on windows ? >> I have a problem playing audio there.
