After experimenting a bit with the last suggestion I ended up<br>
with a buffer-time of 10,000 on the sink and 30,000 on the source. This<br>
seems to suppress voice echoes reasonably well on both test computers.<br>
<br>
My problem now is that there is a strong high pitched echo - it's like<br>
ringing. It's almost as if the suppressor only works on certain frequencies<br>
and leaves others to echo freely. Below is my modified script. <br>
<br>
Any suggestions on how to get rid of this "ringing"?<br>
<br>
wasapisrc buffer-time=30000 ! audioconvert ! audio/x-raw,<br>
layout=non-interleaved ! webrtcdsp noise-suppression-level=high<br>
echo-suppression-level=high ! audioconvert ! webrtcechoprobe ! audioconvert<br>
! wasapisink buffer-time=10000<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">That is strange, I don't recall having hissing, would be unfortunate having to add a band filter afterward. About the sink, check that buffer-time is slightly bigger the latency time, perhaps it has to do with that. Perhaps test difference ns and ec level ?</div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
