The input side may have to charge up the microphone circuit. -Also the initial timing for the output callback may be bursty as it fills the buffer up. -So when the output stream makes its first callback, the input buffer may be overflowing or empty or partially full. - -In order to get into sync we go through a few phases. - -* In Phase 1 we always drain the input buffer as much as possible, more than the output callback asks for. When we have done this for a while, we move to phase 2. -* In Phase 2 we optionally skip reading the input once to allow it to fill up with one burst. This makes it less likely to underflow on future reads. -* In Phase 3 we should be in a stable situation where the output is nearly full and the input is nearly empty. You should be able to run for hours like this with no glitches. |
