MELPe / MELP Vocoder at 2400, 1200 & 600 bps The MELPe - Enhanced Mixed-Excitation Linear Predictive (MELP) vocoder, known as military standard MIL-STD-3005 and NATO STANAG 4591, is a triple-rate low rate coder that operates at 2400, 1200 and 600 bps. Compandent has participated in the research, development, and implementation of the MELPe. And now, Compandent's world-class expertise in speech coding and savvy DSP expertise have taken the MELPe to the next level, the Compandent MELPe suite (a.k.a MELPe++ or MELPe-Plus-Plus). Compandent's MELPe produces better quality than the standard reference! Compandent has also greatly improved and optimized the code. Compandent has ported MELPe to various DSPs by Texas Instruments such as TMS320c54xx, TMS320c55xx, TMS320c64xx, and OMAP. Compandent's MELPe is also "Packetized-Netweork-Ready". You may listen to its audio demo in clean, noisy, and various Frame-Erasure-Rate (FER) conditions. Compandent also created multi-channel & multi-thread POSIX compliant MELPe real-time implementation for various operating systems such as Unix, Linux, Windows PC, Apple, etc..

Compandent offers low-cost Data-Terminal Equipment (DTE) such as FLEXI-232 and FLEXI-PC104 for interfacing MELPe vocoders with external devices such as Rockwell Collins MDM-3001 and other modems.
