Internet Low Bit Rate Codec
RFC 3951, “Internet Low Bit Rate Codec”, is an Experimental document published in December 2004 by S. Andersen, A. Duric, H. Astrom, R. Hagen, W. Kleijn, J. Linden. The canonical text is published by the RFC Editor.
Abstract
This document specifies a speech codec suitable for robust voice communication over IP. The codec is developed by Global IP Sound (GIPS). It is designed for narrow band speech and results in a payload bit rate of 13.33 kbit/s for 30 ms frames and 15.20 kbit/s for 20 ms frames. The codec enables graceful speech quality degradation in the case of lost frames, which occurs in connection with lost or delayed IP packets. This memo defines an Experimental Protocol for the Internet community.
What “Experimental” means
Describes a specification that is part of a research or development effort, published so the community can gain experience with it.
