Tensilica’s AMR Wideband Codec Application Package
The AMR Wideband codec package for the Xtensa HiFi 2 Audio Engine 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 2 Audio Engine is used for other Tensilica audio codecs, enabling the development of highly optimized multi-standard audio SOC designs.
