[Speex-dev] Re: How to reduce jitter buffer size?

[Jean-Marc Valin]

The buffer size of 200 frames has nothing to do with the delay, it's
only the *maximum* number of frames that can be buffered. The Speex
jitter buffer is adaptive and will only use just as much as is required
to compensate for the jitter.
