What you are experiencing is more likely a transport problem and not a
codec problem. The symptoms match pretty well with the following
- Using TCP instead of UDP/RTP
- Not taking into account the drift in clocks between soundcards
- Using a bad (poorly written) jitter buffer.
Oh, and BTW, the decode process is *very* fast (10x faster than
encoding), so I doubt that's where the problem is.
