Hi Jozsef,

this approach sounds interesting.
Do have you have some source code available ?

Thanks

Mark

I have run into the same issue. Before sending a frame to encoder, I calculate the energy. If it is less than a small threshold, I simply replace this frame with "silence frame," which is 320 random samples of values smaller than 3 (16 kHz).

BTW, I have only experience this problem with certain USB headsets that provide you all 0 samples when muted.
