The problem is that now I have two files very similar (one for mic, the other for speaker).<br>If I play them together I can hardly say that they are two different file for most of the file length.<br><br>When I try to cancel the echo, I obtain as output almost the same input.<br>
The update_foreground variable is always 0. I don't get the conditions which must be fulfilled in order to have update_foreground=1.<br>I see that there is some energy comparison, but I don't get the physical meaning of all the components.<br>
Is it normal to get always 0?<br>If the track are into alignment, are there other tracks' properties to consider in order to get a good echo cancellation? Maybe the audio quality? or the relative volume?<br><br>Thanks for any help.<br>
