AMR-WB is defined in ITU standard G.722.2 and referred to as wideband coding of speech using Adaptive Multi-Rate Wideband. Compared to AMR-NB (300-3400Hz) AMR-WB has a much wider bandwidth (50-7000Hz) and provides a much better audio quality. Supported Cores. AS211SFX; AS221BD; EM5D, EM7D; EM9D, EM11D; ARC Audio AMR-WB (G.722.2) Encoder/Decoder
EVS Codec Reveals Superior Performance over AMR-WB …
https://www.spirent.com/blogs/evs-codec-reveals-superior-performance-over-amr-wb
Previous AMR-WB audio codecs can manage approximately 3% of lost frames without critical artifacts, but there is noticeable distortion. In comparison, the EVS codec can perform FEC on more than 15% of lost frames without critical artifacts and still maintain relatively clear voice signals.
