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 better. My question are: 1. Which one is best practice? 2. How to correctly measure...
