Description: The low level speech compression algorithm of the GSM suite is called GSM 06.10 RPE LTP (Regular Pulse Excitation Long Term Predictor). My colleague Dr. Carsten Bormann and I have implemented a GSM 06.10 RPE LTP coder and decoder in C. Its source code is freely available, and we encourage you to use it, play with it, and invent new real time media protocols and algorithms.
Our implementation consists of a C library and a stand alone program. Both are destined to be compiled and used on a Unix like environment with at least 32 bit integers, but others have ported it to VMS and a MS DOS 16 bit environment. GSM 06.10 is faster than code book lookup algorithms such as CELP, but by no means cheap to use it for real time communication, you will need at least a medium scale workstation. -The low level speech compression algorithm of the GSM suite is called GSM 06.10 RPE LTP (Regular Pulse Excitation Long Term Predictor).

Description: 2.4 kbps MELP Proposed Federal Standard speech coder
Fixed-point C code, version 1.0
The fixed-point version of the voice codec Mixed Excitation Linear
Prediction (MELP) is based on specifications on the C-language software
simulation contained in GSM 06.06 This standard is available from the ETSI publication office
Department of Defense to use the C-language software simulation contained
in GSM 06.06 for the purposes of the development of a fixed-point
version of the voice codec Mixed Excitation Linear Prediction (MELP).

Description: C代码实现的AMR语音编解码。AMR多速率编解码技术相比原有的GSM语音编码器采用固定的编码速率，AMR语音编码器则可根据无线信道和传输状况来自适应地选择一种最佳信道模式（全速率或半速率）和信源编码模式（以比特率来区分）进行编码传输。-C code to achieve AMR voice codec. AMR multi rate coding and decoding technology of GSM speech coder is compared to the original fixed code rate, AMR speech coder can be based on the wireless channel and the transmission state to adaptively an optimal channel mode (full rate or half rate) and source coding mode (to distinguish between the transmission with a bit rate).
