2224 Voice Packetization, Codecs and Voice Quality

Voice Packetization, Codecs and Voice Quality is the "nuts and bolts" of Voice over IP: how the voice is digitized and coded, time stamps applied with the RTP protocol, and how the result is carried in UDP, IP packets and MAC frames.

You'll learn about codecs and compression, and understand factors like delay, jitter and packet loss, what causes them, and how they affect sound quality. Sample sound clips with lost packets and uncorrected timing variations are included so you can hear the effects.
