'''G.718''' is an [[ITU-T]] standard embedded [[scalable]] speech and [[audio codec]] providing high quality narrowband (250 Hz to 3.5 kHz) speech over the lower bit rates and high quality wideband (50 Hz to 7 kHz) speech over the complete range of bit rates. In addition, G.718 is designed to be highly robust to frame erasures, thereby enhancing the speech quality when used in [[internet protocol]] (IP) transport applications on fixed, wireless and mobile networks. Despite its (contracted; show full)

The codec also incorporates an alternate coding mode, with a minimum bit rate of 12.65 kbit/s, which is bitstream interoperable with [[ITU-T]] Recommendation [[G.722.2]], 
[[3GPP]] [[AMR-WB]] and [[3GPP2]] [[VMR-WB]] mobile wideband speech coding standards. This option replaces Layer 1 and Layer 2, and the layers 3-5 are similar to the default option with the exception that in Layer 3 few bits are used to compensate for the extra bits of the 12.65 kbit/s core. The decoder is further able to decode all other [[G.722.2]] operating modes. G.718 also includes [[discontinuous transmission]] mode (DTX) and [[comfort noise]] generation (CNG) algorithms that enable bandwidth savings during i(contracted; show full)
