  • From what I understand, the echo cancellation is built in the WASAPI. I think the quality depends on the specific audio device that you are using. There are many brands of hardware that acts differently. To improve quality of echo cancellation you should always lower the volume of your speakers and try to keep them away from your microphone. If this does not  help, you can try integrating an open AEC code and compile/tune it to your system. Alternatively, try a commercial product for noise reduction software like SoliCall Pro that is also equipped with a professional acoustic echo cancellation.
