Yes, it is like an echo canceller works.<br>
<br>
After some checks, i think the echo canceller built inside is a better choice than the EC pulseaudio module.<br>
<br>
Thanks

<div>Thank you very much Tomaz. It seems baresip has an EC built inside, as Russell said in a previous comment. If it doesn't work correctly, i will try your updated version of webrtc.<br>

Thanks a lot, <br>

I'm seeing these kinds of errors constantly with module-echo-cancel<br>
(also running on ARM):<br>
<br>
module-echo-cancel.c: Doing resync<br>
module-echo-cancel.c: Playback too far ahead (22312), drop source 2<br>
852<br>
module-echo-cancel.c: Doing resync<br>
module-echo-cancel.c: Playback after capture (-1309936), drop sink<br>
167708<br>
<br>
I don't know what their cause is, but for me they don't seem to be<br>
causing any noticeable audio quality problems.<br>
<br>
I do find the current state of echo cancellation in Pulseaudio unusable,<br>
but that seems to be due to the echo cancellation algorithm not working<br>
properly for my use case. It might be the same for you.<br>
<br>
I've made an updated libwebrtc-audio-processing and a patched<br>
module-echo-cancel that works significantly better for me. I've sent it<br>
out to this list three months ago without much response.<br>
<br>
You might want to try it if it helps with your problems. You can get the<br>
code here (both should build with "dpkg-buildpackage" on debian-like<br>
systems):<br>
