摘要
在对一些语音编码进行筛选后,3GPP把增强的AMR-WB(AMR—WB+)编码作为其标准,它能在10~24Kb/s的范围内获得良好的性能。介绍了移动通信中语音服务的需求和AMR-WB+的技术概览,由此可知,AMR-WB+为移动通信中语音服务提供了良好的音频质量。
After an audio codec selection, 3GPP has standardized the AMR-WB+(Extended Adaptive Multi-Rate-Wideband) codec that has unique performance at 10-24 Kb/s. The requirements imposed by mobile audio services are discussed, and a technology overview of AMR-WB+ is addressed. AMR-WB+ can match these requirements while provides outstanding audio quality.
