Featuring music encoding with quality beyond CDs, plus iPod and mobile phone compatibility, Fraunhofer's HD-AAC codec offers a new way of storing, streaming and distributing music on portable devices, within the connected home and through online music stores, replacing the physical media CD. Unifying MPEG-4 SLS and Advanced Audio Coding standards (AAC), Fraunhofer's HD-AAC codec provides future-proof, lossless compression of music with up to 24-bit quality. Via ARM Powered platforms, Fraunhofer IIS is efficiently making HD-AAC available to consumers, broadcasters, electronic music distributors and the consumer electronics industry.

This article, which includes a detailed explanation of the principles of audio codecs, outlines the technical and business cases for this new technology.
