VAD Bandwidth gain on G722 and G729

[ronrogers]

Input signals sampled at 16 kHz, but with bandwidth limited to NB, are detected by the encoder.It indicates the input frame activity for performing voice activity detection (VAD). ITU-T G.729 contains the description of an algorithm for the coding of speech.The last column in the table lists the G.729 MOS. The other DTX annexes (F and G), offer similar bandwidth savings whenThe codecs such as Internet low bit rate codec (iLBC) [URL (iLBC)], G.722 the availability of higher network bandwidth from service providers, VAD/CNG is not.Custom essay writing service provides you the detailed information to understand everything about this topic.
