Company Overview

Compandent the leader in voice compression creates leading-edge innovative DSP algorithms and implementations for next-generation telecom products including voice compression, multimedia, packet networks, noise suppression and acoustic echo cancellation. Compandent also participated in the development of the MELPe vocoder standard, and ported it to TI DSPs such as TMS320C54x, TMS320C55x, TMS320C64x, c64+, c674x, L137, L138, OMAP, etc. We developed the "golden reference" MELPe based hardware and software for NSA and NATO.


Compandent specializes in voice compression and voice enhancement, and sells high quality MELPe software & hardware and enhancement software modules e.g. EchoKiller and NoiseMuter. Compandent provides MELPe related software & hardware modules, e.g. low-cost MELPe devices (DTE) FLEXI-232 that comes with TI DSK boards or in PC-104 form factor. Compandent MELPe packages and DTE devices use TMS320C54x™, TMS320C55x™, or TMS320C64x, c64+, c674x, L137, L138. Our MELPe suite is a hand optimized real-time implementation of the 2400 / 1200 / 600 bps MELPe vocoder, U.S. and NATO standard vocoder (MIL-STD-3005, STANAG 4591).
