Fraunhofer IIS Brings MPEG Audio Codec Suite to NXP Semiconductors

March 3, 2020 Tiera Oliver

Fraunhofer Institute for Integrated Circuits (IIS) announced that NXP Semiconductors will support Fraunhofer’s MPEG Audio Software Development Kit (SDK).

MPEG-H Audio is an advanced audio system for UHD-TV and streaming. It supports both sound and the ability for users to adjust elements in the audio to their preferences. MPEG-H is the distribution format of the new music streaming service 360 Reality Audio. Fraunhofer offers MPEG-H software implementations for many popular CPU, SoC, and DSP platforms. It is deployed today in TV sets, premium sound bars and high-end smart speakers.

This software package covers four generations of audio codecs: legacy MPEG Layer-1/2/3, the next-generation MPEG-H 3D Audio standard, and the AAC codec family, including xHE-AAC. NXP will incorporate these codecs into its multimedia system solutions for audio quality in home entertainment products, such as set-top boxes, sound bars, or smart speakers.

xHE-AAC is a solution for digital radio broadcasting, for adaptive audio, and video streaming services over the Internet. It offers a bit rate range from 12 kbit/s to 500 kbit/s and above for stereo services, combined with seamless bit rate switching over DASH and HLS, as well as mandatory MPEG-D DRC loudness and dynamic range control. The codec is natively supported by the Android 9 and 10 operating systems, as well as iOS 13 and Amazon Fire OS 7.

NXP also plans to leverage the Fraunhofer MPEG-H Audio System Trademark Program to test its MPEG-H decoder implementation. This will indicate to manufacturers that NXP’s decoder implementation fulfills all mandatory requirements of Fraunhofer’s MPEG-H Audio System trademark program.
