HD-AAC

Overview

HD AAC 

The new MPEG HD-AAC® codec offers music quality superior to the CD and compatibility with iPods and AAC-enabled mobile phones. Based on the MPEG-4 SLS and AAC-LC standards, Fraunhofer's HD-AAC provides future-proof, lossless compression of 16/24-bit and up to 192 kHz quality music content. Today's CDs store uncompressed audio in 16-bit, 44.1 kHz quality, despite the fact that most music is now produced in the improved 24-bit, 96 kHz format. The underlying objective for HD-AAC, therefore, is to make this new high-quality sound experience conveniently available to consumers, electronic music distribution services and the consumer electronics industry.
