Please keep the following limitations in mind when using the new "enhanced" mode of the Microphone:
- You can only use a *single* enhanced audio capture at any given time. So it is not possible to open another browser and run OpenMeetings using the same device. It might be also that you cannot use Skype or other applications that try to access the microphone at the same time while you are using the Microphone in OpenMeetings Sebastian 2013/2/17 [email protected] <[email protected]> > I have enabled the AEC feature in the client in r1446971. > There might be some new options to check in the enhancedOptions. > Basic guide is here: > > http://www.adobe.com/devnet/flashplayer/articles/acoustic-echo-cancellation.html > Some of them could be made configurable in the config.xml, but I had no > time yet to look into it more detailed. > > @Maxim If the issue with the file permission and the mxmlc executable is > fixed, IMHO you can close OPENMEETINGS-529 > @George You are welcome to test with your users > @Timur Theoretically we can use SPEEX codec.
