Tensilica’s AMR Wideband Codec Application Package
The AMR Wideband codec package for the Xtensa HiFi Audio DSPs implements AMR wideband (WB) speech decoding and encoding (G.722.2) and is fully compliant with the 3GPP specification for the AMR WB codec. The codec is a fixed-point implementation written entirely in C and available in either object or source code. Included documentation describes how to incorporate the decoder into a system. Using this package, system developers can integrate an AMR WB codec into an SOC without the need for additional optimizations or software development. The same Xtensa HiFi Audio DSPs are used for other Tensilica audio and voice codecs, enabling the development of highly optimized multi-standard audio and voice SOC designs.
