Cadence expands Tensilica HiFi audio/voice software library

Cadence Design Systems, Inc. (NASDAQ: CDNS) and Fraunhofer IIS said that Cadence has 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 over 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.

Cadence enables global electronic design innovation and plays an essential role in the creation of integrated circuits and electronics. More information about the company, its products, and services is available at
