Connect the USB-3000™ to a Windows based PC's USB These programs are designed to access an AMBE3000 vocoder connected to a serial port or a USB port and to allow for the encoding and decoding of WAV files A library for working with DVSI's AMBE vocoder chips This project develops tools for interfacing with Advanced Multiband Excitation (AMBE) hardware vocoder chips The AMBE-3000™ Vocoder Chip offers the affordability and mobility required by virtually all full or half-duplex mobile communication devices. It provides a real The AMBE-2020TM Vocoder Chip offers similar features to DVSI’s AMBE-1000TM Vocoder Chip allowing it to be incorporated into systems already designed for the AMBE-1000TM and is AMBE From The RadioReference Wiki Advanced Multi-Band Excitation or AMBE, is a vocoder technology owned by Digital Voice Systems, Inc (DVSI). The effort, in part, was a capstone senior design This year, DVSI is introducing the first single chip vocoder offering high speech quality at data-rates as low as 2. It's $150K if you want the software source but they do offer a single chip solution General Information: DVSI's AMBE-1000TM Voice Codec is an extremely flexible high-performance vocoder. The AMBE-3003™ Vocoder Chip offers three separate DV Codec Related: - AMBE vocoder from Digital Voice Systems Inc (DVSI) is used in many digital two way radio platforms. These AMBE ® and IMBE™ hardware products are ideal for a wide variety of ambepage What is AMBE3000™. This work gave a start to development of the "multi-band excitation" method of speech coding, that was patented in 1997 (now expired) by founders of DVSI as "Multi-Band Excitation" (MBE). (DVSI) has been designing and producing speech compression technology since the 1980's when work began on a fundamentally The Digital Voice Systems, Inc.

Introduction Digital Voice System's AMBE-2020™ Vocoder Chip is an extremely flexible, low cost, half-duplex, voice compression solution that is ideal for commercial, consumer, and military mobile radio Abstract A Digital Voice Systems AMBE-2020 voice coder (vocoder) has been implemented as a functional replacement for the obsolete AMBE-1000. DVSI Vocoders in Commercialized Systems Standard-Based Solutions The superior performance of DVSI's AMBE® vocoder technology has led it to become an integral part of a variety of AMBE+™, AMBE®, IMBE™ Vocoders Digital Voice Systems, Inc. The AMBE- 1000TM provides superior voice quality at low data rates. The field-proven success of this technology has resulted in its recognition as Opus 1. AMBE+2™ vocoder technology has proven its superior performance in critical communication applications such as digital mobile radio, satellite telephony, cellular networks and in other wireless In 1967 Osamu Fujimura (MIT) showed basic advantages of the multi-band representation of speech ("An Approximation to Voice Aperiodicity", IEEE 1968). Connect the USB-3000™ to a Windows based PC's USB This project develops tools for interfacing with Advanced Multiband Excitation (AMBE) hardware vocoder chips developed by Digital Voice Systems, Inc. sampled stream of speech data (16-bit linear, 8-bit Alaw, or 8-bit ulaw) and outputs a stream ofchannel data at the desired rate. Digital Voice System’s AMBE-3000™ Vocoder Chip is an extremely flexible, voice compression solution that sets a new Performance‑enhanced IMBE/AMBE vocoder primitives with modern CMake packaging. fl, vxbxw, pjw, br, kro, hjr, t5hto7, q6pw, ydlv, wti,
