AMBE+2: THE WORLD'S MOST ADVANCED VOICE COMPRESSION TECHNOLOGY

Use of the AMBE standard requires a license from Digital Voice Systems, Inc. While a licensing fee is due for most codecs, DVSI does not disclose software licensing terms. Anecdotal evidence citation needed suggests that licensing fee begin from between $100,000 to $1 million. For purposes of comparison, licensing fees for use of the MP3. Through the loudspeaker I can hear AMBE reproducing the pitch fundamental – a bass note that can be heard on some males (e.g. 7), whereas Codec 2 is filtering that out. I feel AMBE is a little better, Codec 2 is a bit clicky or impulsive (e.g.

Digital Voice Systems, Inc. (DVSI) developed the revolutionary voice compression model – Advanced Multiband Excitation (AMBE) – to provide superior voice quality and performance at low data rates. DVSI’s AMBE speech compression (vocoder) software is more efficient and less complex than traditional linear prediction-based speech models and therefore enables more cost-effective implementations and system designs.

The premier AMBE+2™ Vocoder sets the standard for high-quality, high-performance speech at data rates from 2.0 to 9.6 kilobytes per second. The AMBE+2™ vocoder has been shown to outperform DVSI’s previously industry-leading AMBE+™ Vocoder as well as the G.729 and G.726 vocoders, while operating at only 4.0. KBPS. The AMBE+2™ has been designed to be particularly robust and perform exceptionally well under bit errors and extreme acoustic background noise conditions. Once again, DVSI has raised the bar on performance expectations regarding low-rate vocoders across the entire mobile industry.

The superior performance characteristics of the AMBE+2™ Vocoder make it ideally suited for mobile radio, secure voice, satellite communication, computer telephony, digital voice and storage applications where bandwidth is at a premium and high-quality at low>
