Comment (by krisha):
I attached a sample with 6 bad frames marked as BAD_SPEECH (Q cleared) at
~ 1s 660ms. I hear a small noise. But now I'm not totally sure, if in this
implementation the Q bit is needed. Maybe the implementation automatically
decreases the volume of bad frames even without using the Q bit. If so, a
comment in the code would have been nice :)
I will continue to play with that and let you know about my results.
Please ignore the NO_DATA (0x7C) after the bad frames in the sample.
