# CODECPRO G.722.2/AMR-WB CODEC  3GPP AND ITU-T STANDARD CODEC

G.722.2/AMR-WB is the first codec to be adopted as a standard for both wireless (3GPP) and wireline (ITU-T) services. Supporting a wide range of bitrates from 6.6 to 23.85 kbps, AMR WB/G.722.2 was adopted at ITU for teleconferencing and voice-over-packet applications. AMR-WB is the mandatory standard codec for wideband speech in GSM and WCDMA networks and is also included in the CableLabs PacketCable 2.0 specification. G.722.2/AMR-WB supports dynamic adaptation to network conditions, using lower bitrates during network congestion or degradation while preserving audio quality.
