Description: ITU-T G.722.2
国际电信联盟G.722.2建议书，2003年7月版。该建议书是语音通讯领域的压缩标准，被GSM，WCDMA，3GPP等采用，题目为16kbit下的宽带语音编码，使用自适应多率宽带编码。
内容主要有代数码激励线性预测编码(ACELP)，话音活动检测(VAD)等。-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.

Description: WB-AMR VMR-WB 是新型可变速率多模式宽带语音编解码器，专为无线 CDMA 2000标准而设计，目的在于在 50 至 7000 HZ 的频带上进行语音编码，采样率为 16 KHZ。VMR-WB 基于 3GPP AMR-WB (G722.2) 编解码器，在每秒速率12.65 Kbit 上可实现互操作。 VMR-WB 工作模式有四种，具体选择哪种应视网络的流量情况而定。前三种模式专门针对 CDMA 系统，而第四种模式为 AMR-WB 互操作性模式。 VMR-WB 与 AMR-WB 的互操作性允许 GSM/WCDMA 与 CDMA2000 系统无须进行自动解码即可通信，这就不至于增加额外的延迟以及引起语音质量下降-WB-AMR VMR-WB is a new variable-rate multimode wideband speech codec designed for wireless CDMA 2000 standard design, aimed at 50 to 7000 HZ frequency band for voice coding, sampling rate of 16 KHZ. VMR-WB based on the 3GPP AMR-WB (G722.2) codec rate of 12.65 Kbit per second can be interoperable. VMR-WB mode four, the specific choice of which network traffic should be as the case may be. The first three models specifically for the CDMA system, while the fourth mode of AMR-WB interoperable mode. VMR-WB and AMR-WB allows the interoperability of GSM/WCDMA and CDMA2000 systems can not automatically decode the communication, which without increasing the delay and the additional decline in voice quality caused by
