Anyone knows how to resolve this? I dont know if this is Wowza problem or code problem because this code worked without noise on Flash Media Server 7 years ago. (without even using Echo Cancellation above)
I recommend using a different capture device (microphone/camera) this could be an external or even a different machine altogether. If you're not getting the same result when using a completely different capture device, laptop or desktop PC then would suggest an issue is caused by either the capture device itself or the machine using it. As Salvadore stated, this is not something that can be fixed within Wowza, as Wowza can only provide what it receives.
