Benefits of HD-AAC:

  • Audio quality superior to CD (24-bit audio, up to 192 kHz)
  • State-of-the-art lossless compression preserving every bit of information
  • Compatible with many mobile phones and PMPs (i.e. Apple iPod®)
  • Full Metadata support including cover art, ID3 tags and lyrics
  • Based on the ISO MPEG-4 AAC-LC and SLS open standards
  • Maximized sound quality under difficult network conditions
  • High error robustness and boundless editing possibilities

The new HD-AAC codec offers music quality superior to the CD and compatibility with iPods and AAC-enabled mobile phones. Based on the MPEG-4 standards SLS and AAC-LC, Fraunhofer's HD-AAC provides future-proof, lossless compression of 16/24-bit 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.
