G.726 Vocoder Employed for Speech Transmission

Toronto, Canada – GAO Research Corporation. (world wide web.GAOResearch.com) is providing its G.726 vocoder that is a superset from the ITU-T G.721 and G.723 standards and it is initially designed like a half-rate option to G.711 audio companding. It’s utilized in numerous programs for example speech transmission over digital systems, interactive video, multimedia, and ISDN communications.

GAO Research’s G.726 vocoder matches the ITU-T standard and works at 40, 32, 24, and 16 killerbytes per second. It converts a 64 Killerbytes per second A – law or -law PCM funnel to or from the 40, 32, 24 or 16 killerbytes per second funnel. The conversion is used towards the PCM bit stream utilizing an ADPCM transcoding technique. Thus, the plan has switchable transmission rates supplying 4 kHz of audio bandwidth in conformance using the ITU-T standard.

This G.726 vocoder can scribe 13 or 14-bit PCM samples or 8-bit, A-law or law encoded data into 2, 3, 4, or 5-bit code words. Because the formula encodes one sample at any given time, the coding or decoding delay is effectively zero supplying for robust, quality audio. Additionally, processing frame size and input/output formats is user selectable.

This high end G.726 Vocoder goes to GAO’s group of Speech Vocoders. This line includes G.728 LD-CELP Vocoder which implements the reduced delay code-excited linear conjecture (LD-CELP) speech compression technique specified by the ITU-T standard and offers roughly 4 kHz of speech bandwidth, G.729, G.729A and G.729AB Speech Vocoders which offer toll-quality speech with only moderate processing needs and delay occasions as well as succeed in the existence of random bit errors.

All GAO Research’s speech software have passed the exam vectors per the ITU GAO also adheres to stringent qc methods, that is reflected within the well structured code, detailed design documentation and well-defined design and test plans. This guarantees easy integration, easy maintenance along with a smooth upgrade path for more generation customer items.
