G.728

G.728, based on the Low-Delay Code Excited Linear Prediction (LD-CELP) compression principles, is a 16 kbps compression standard. G.728 has an algorithmic coding delay of 0.625 ms. G.728 normally compresses toll quality speech at 8000 samples/second. G.728 Annex G (G.728 G) is a fixed point specification of the coder working at a bit rate of 16000 bits/second. G.728 Annex I (G.728 I) is the packet loss concealment (PLC) technique used along with G.728 G. G.728 coders are widely used for applications of telephony over packet networks, especially voice over cable and VoIP, where low delay is required.
