Tensilica Adds G.729AB Speech Codec for Its Popular HiFi 2 Audio Engine.Fully Compliant with ITU (International Telecommunication Union, Geneva, Switzerland, www.itu.ch) A telecommunications standards body that is under the auspices of the United Nations. Comprising more than 185 member countries, the ITU sets standards for global telecom networks. Specifications for G.729 Standard with Annexes A and B SANTA CLARA, Calif. -- Tensilica[R], Inc. today introduced another codec for its popular HiFi 2 Audio Engine and Diamond Standard 330HiFi processor core which are specifically optimized for audio in mobile multimedia devices. The G.729AB speech codec, mostly used in Voice over IP (VoIP) applications, is fully compliant with ITU (International Telecommunication Union International Telecommunication Union (ITU), specialized agency of the United Nations, with headquarters at Geneva. It was created in 1934 as a result of the merging of the International Telegraph Union (est. ) specifications for the G.729 standard with annexes A and B. As an ITU standard, G.729 is one of the most tested and lowest bandwidth digital speech transmission standards. "Our HiFi 2 Audio Engine customers have requested the G.729 speech codec for the development of their next generation VoIP enabled products," stated Larry Przywara, Tensilica's director of mobile multimedia products. "With toll quality performance at very low bandwidth, G.729 support has become a standard requirement in VoIP systems." The G.729 data compression algorithm compresses voice audio at low bit rates, offering opportunities for significant increases in bandwidth utilization in existing telephony applications. Tensilica's codec implements G729A, which is compatible with G.729 but requires less computation, and G729B, which is a silence compression scheme with Discontinuous Transmission (DTX), Voice Activity Detection (VAD (Value Added Dealer) Same as VAR. ), Comfort Noise Generator (CNG CNG Compressed Natural Gas CNG Calling (Tone) CNG Comfort Noise Generation CNG Cryptography Next Generation (Microsoft Windows Vista) CNG Centre National de Génotypage ) and Silence Insertion Descriptor (SID). Pricing and Availability The G.729AB codec is available now for all licensees of Tensilica's Diamond Standard 330HiFi or the Xtensa HiFi 2 Audio Engine. Pricing starts at $8,000 for a decoder single project license.
