Hello,
when noise discrimination in enabled, is there any way you can know if VOIP engine has detected noise?
Thanks

Hi hermes,

No, the media engine does not send an event to your application when it determines that transmitted audio signal strength falls below the local recorded audio threshold/level as set by the SetNoiseThreshold() API procedure.

Let us know if we are lacking any needed functionality.

By the way… what are you currently working on?


Thanks,

Randal

RTP stream is continuously monitored for us (basically jitter variation and loss packets) and we can´t calculate jitter properly when packets are not transmitted, so we´re going to use our own VAD to solve it.
Now we are still working with our speech recognition system. We have just started a pilot test with around 50 people.
I haven´t forgotten that I´ve got a pending post about 'Mixer resample' problem, I think that next week I´ll have some more time to do it. Sorry for the delay.
Thanks again.
