Single frame or multiple frame inside rtp packet?
Hi,
Sorry if my question not related to speex.
I have created a voip application using speex. My
internet line is 64Kbps.
I`m using narrow band mode, 8000 bitrate, 20ms of
8000Khz sampling rate, no buffering, no preprocessing,
just set bitrate and go.
When i send single frame inside rtp the sound was not
good, choppy and noisy. But when i pack around 8 frame
inside rtp packet, the sound was
