ITU-T G.722.2 (07/2003)

عربي | 中文 | English | Español | Français | Русский
Wideband coding of speech at around 16 kbit/s using Adaptive Multi-Rate Wideband (AMR-WB)
This Recommendation describes the high quality Adaptive Multi-Rate Wideband (AMR-WB) encoder and decoder that is primarily intended for 7 kHz bandwidth speech signals. AMR-WB operates at a multitude of bit rates ranging from 6.6 kbit/s to 23.85 kbit/s. The bit rate may be changed at any 20-ms frame boundary.Annex C includes an integrated C source code software package which contains the implementation of the G.722.2 encoder and decoder and its Annexes A and B and Appendix I. A set of digital test vectors for developers is provided in Annex D. These test vectors are a verification tool providing an indication of success in implementing this codec. G.722.2 AMR-WB is the same codec as the 3GPP AMR-WB. The corresponding 3GPP specifications are TS 26.190 for the speech codec and TS 26.194 for the Voice Activity Detector.
