Speex dev - Jan 2007 - How to reduce jitter buffer size?

Hi,

I looked at the jitter buffer code and it seems like the maximum number of
frames
that Speex can hold up to is 200 (SPEEX_JITTER_MAX_BUFFER_SIZE).  This is
equivalent to 4 seconds (20msec/frame * 200 frames).  Can I just reduce this
constant to limit the size?  I know I'll reduce the smoothness of delayed
frames
but I want to reduce the delay in case my audio application isn't servicing
the
frames in time and hence the delay will grow as more frames are queued up.  I
pretty real time voice if there's a little interruption in the voice stream.

Regards,
Andy

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.
