Hi, Sorry for being unclear :) Was trying to say: please check the fix in #658, which contains audio level manipulation. IIRC, the story behind that fix was: according to (our understanding of) G722 spec, G722 input/output is 14 bits. So, r2342 basically converts audio sample from 16-bits to 14-bits before encoding and "returns back" the 14-bits to 16-bits after decoding. And after this fix, pjmedia G722 seems to work fine with VoiceAge implementation of G722. IIRC again, some other implementations don't do 16<->14 bits conversions, so when pjmedia G722 is talking to those G722 implementations, such problems of over-driven level and audio clipping may occur. In this case, *reverting* (instead of including:) ) r2342 will resolve the problem. However, I'm afraid that we may prefer to stay with r2342. Any feedbacks or suggestions are welcome.
