<p>Setting it to 10 or so doesn't help, it seems that just the threshold of detection is changed (ok, that's what is expected), not the time until the decision is made.</p>
<p>The audio clipping is a timing issue. <br>
Does there exist something like a "minimum time" that this algorithm needs to detect talking after silence? What happens to the audio that was sent by that member during this time, does.the algorithm discard that?</p>
<p>Greetings,<br>

Typically, if a conference member didn't have audio for some time and then begins to speak, the first syllable will be clipped and cannot be heard by the other conference participants.</div>
<div><br></div><div>We ruled out a number of possible causes, and finally discovered that the energy level detection algorith seems to be the source of the problem. Setting the energy level for all participants to "0" heals the problem (of course now the noise might be higher since every participant's noise contributes to the total noise), but this setting is not very useful since the "talking detection" seems to rely on the same level, i.e. with energy "0", all members are marked talking all the time (which effectively renders the "talking" display useless).</div>
<div><br></div><div>Is there any chance to tune the energy level detection time (!), or to de-couple talking detection an energy level detection in FreeSwitch?</div><div><br></div><div>Best regards,</div><div>Roland</div>
