![]() ![]() The field-proven success of this technology has resulted in its recognition as the standard for voice quality in communication systems around the globe. The AMBE-2000™ Vocoder Chip implements DVSI’s patented and award winning AMBE® Voice Compression Algorithm. DVSI's MBE based technology possesses many advantages over traditional linear prediction-based techniques, allowings DVSI's vocoders to deliver higher voice quality at lower bit rates as compared to CELP, MELP, VSELP, LPC-10, etc. DVSI based its efforts on the innovative, Multi-Band Excitation (MBE) speech model developed by Griffin and Lim at MIT in the mid 1980's. The AMBE chips are manufactured by Digital Voice Systems, Inc.(DVSI).ĭVSI began with the goal of developing a new, robust speech compression system that would outperform the methods that existed at that time. AMBE is implemented in the AMBE-2000 or AMBE-2020 chips which are implemented inside of a D-STAR radio. ![]() Memory Downloads for Non-DR Mode Radios by regionsĪMBE - Advanced Multi-Band Excitation is the technology that is used in D-STAR to compress the voice for transmission.Repeater List Downloads for DR Mode Radios.D-STAR InfoCon Dayton Hamvention 2012 Schedule. ![]()
