Toronto, Canada – GAO Research Corporation. (world wide web.GAOResearch.com) is providing its G.728 LD-CELP vocoder for digital circuit multiplication equipment, videoconferencing, digital telephony, and multimedia items. This G.728 vocoder works at 16 killerbytes per second and 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. Using backward-adaptive linear predictive coding analysis, with the ability to acquire a low transcoding delay of two ms. The ITU-T G.728 standard identifies the encoding of 8 kHz tried speech signals for transmission on the 16 Killerbytes per second funnel. Aside from the above mentioned, this G.728 vocoder uses adaptive publish filter to boost performance for multiple transcodings(VAD). This G.728 LD-CELP vocoder goes to GAO’s group of Speech Vocoders. This line includes a multitude of speech vocoders for speech processing software and audio processing codecs, for example G.729, G.729A and G.729AB Speech Vocoder which succeed in the existence of random bit errors, G.726 Vocoder, G.722.2 (AMR-WB) Vocoder along with other similar items.
