...ain extend for me, and does not seem to completely remove noise from sound card. Even if you unplug the microphone, it still could not get rid of the noise.

...nclude: I'm really happy with the AGC + denoiser. Adjusting the mic volume level is no longer necessary, and having the denoiser automatically adapt to changing noise conditions is valuable. If echo cancellation worked, that would be the icing on the cake.

Hi, So I have had a chance to delve deeper into the new pre-processing code- I was also able to get VAD, AGC, Denoising, etc working inside of the current release candidate (1.0.3). For some reason, the 1.1.2 release didn't properly encode/decode in our system (on windows) and I haven't had time to determine why. In any case, all of the features jointly work very well- great job! I
