Hi Benny, I have coded a little application based on simpleua. The mic signal is a little bit to quiet. The mic volume from the os is 100%. Is there a way to gain the signal with pjmedia. I read about pjmedia_conf_adjust_tx_level. However, there is no conference bridge in simpleua. What is the easiest way to add this in simpleua. Alternatively, is there an other way to gain the signal? Thanks and best regards, Matthias -------------- next part -------------- An HTML attachment was scrubbed...
