Geneva - Feb 6, 2014 - The DRM Consortium announced that a recently implemented licensing agreement between Cadence and Fraunhofer IIS, will facilitate the ability of the Cadence platform to decode DRM audio.

On Jan. 6, 2014, the two companies announced that Cadence had licensed the full suite of MPEG AAC codecs from Fraunhofer IIS for use with the Tensilica HiFi DSP. Cadence plans to use the products to enhance the library of more than 100 audio/voice software packages optimized for the HiFi DSP family. New standards include the AAC-ELD (Enhanced Low Delay) communication codec, which enables telephone conversations with the highest possible audio quality, and xHE-AAC (Extended High Efficiency AAC), which is the latest upgrade to the MPEG AAC family of codecs.

The xHE-AAC MPEG audio codec is the first to combine speech and general-purpose audio coding in a unified system, allowing for high quality delivery of any type of audio content at virtually any bit-rate. In addition, the library adds full support for DRM Digital Radio Mondiale audio decoding according to the latest ETSI system specification, bundling xHE-AAC and HE-AACv2 for all DRM modes (DRM30, DRM+).
