Hi, When i include a ',' in the application data, for example: exten => 1,1,Plaback(echo,file); [My file name is "echo,file"] the Playback application receives echo|file as data parameter. How can avoid asterisk change the ',' character? (The change code is in asterisk/pbx/pbx_config.c Ln 1150). I'm developping an application for asterisk and i need to pas...

Hello! I'm attempting to implement Speex AEC support in GStreamer, using work started by Olivier Cr?te. In the Speex manual, I see this text: "Using a different soundcard to do the capture and plaback will *not* work, regardless of what you may think. The only exception to that is if the two cards can be made to have their sampling clock ``locked'' on the same clock source." This is of course a major issue, because people may have webcams with embedded mics, and cancellation re...

...cancellation, but there are large discrepancies in the audio between uses of the application. Sometimes there is no echo, sometimes there is full echo. Sometimes the echo will fade in and out. Now, I read this on your troubleshooting section: "Using a different soundcard to do the capture and plaback will *not* work, regardless of what you may think. The only exception to that is if the two cards can be made to have their sampling clock ``locked'' on the same clock source." I've also come to realize that there can be a slight clock drift between the microphone and speakers on...

...e a video conference component. For that I need echo cancellation, and is looking around for algorithms/implementations of that, and the one in speex is an alternative. In the documentation for speex I find the following sentence however. "Using a different soundcard to do the capture and plaback will *not* work, regardless of what you may think." If this still is true, the Speex echo canceller is basicly a no-go for us. There is no way I can get the customers to understand why they can't use e.g the microphone in their webcam together with the speakers connected to the built-...

Hi Marc, thanks for the quick reply.
