RE: Open Source DSTAR Voice - Codec2: by W3JKS on JMail this to a friend! The RETAIL price of one AMBE codec. Any other software that might access the FCD is shut. (ALAC) Apple QuickTime libalac FFmpeg Free Lossless Audio Codec (FLAC. This was because D-Star uses an early version of the AMBE codec.

More details can be found on DVSI’s AMBE+2 product page.Latest Ambe Codec Software 2016 - Free Download Software 2016. The company can also provide hardware development kits (HDK) based either on AMBE-3000 or AMBE-4020 AMBE+2 chip, USB based products from a single channel dongle to a the 12 full-duplex channel USB-3012 product, as well as Net-2000 VCUs (Voice Connect Unit) that bridge analog speech I/O to an Ethernet network for example for VoIP or voice-monitoring / recording products (for the CIA? :)). DVIC claims the technology is already used in digital mobile radio and satellite telephony solutions such as Inmarsat, Iridium, DMR Communication PBX, etc… AMBE-4020 HDKĪMBE+2 voice compression algorithm is available for DSPs and CPUs from Texas Instruments, Analog Devices, ARM, MIPS, Intel, NXP, and others, and runtime environments are available for Windows, Linux, Android, iOS, VxWorks, uC/OS, and other operating systems on request. You can listen to male and female samples at different bitrate for your own evaluation. Low complexity reduces implementation costs.Eliminates fixed data-rate and codebook problems.Does not require the use of a residual signal.Uses fewer computations than CELP ( Code-excited linear prediction) as used in G.729.Resistant to background noise and channel bit errors.

Maintains speech intelligibility and speaker recognition at rates as low as 2.0 kbps.

The solution can be integrated into product either using software licensing, or through Vocoder chips, and the company lists the following key benefits: Digital Voice Systems (DVSI) claims to have gone even lower thanks to their AMBE+2 vocoder (Advanced MultiBand Excitation) providing high-quality speech at data rates from 2.0 to 9.6 kilobytes per second.ĪMBE+2 vocoder is said to outperform the company’s previous generation AMBE+ Vocoder as well as the G.729 and G.726 vocoders, while operating at only 4.0 Kbps. The vocoder is suitable for mobile radio, secure voice, satellite communication, computer telephony, digital voice and storage applications AMBE+2 Vocoder Chips Opus 1.2 open source audio codec was release a few months ago with the ability to deliver low power low high-quality audio bitrate for speech with bitrates as low as 12 Kbps.
