  • Backward Compatible to mp3
  • File extension .mp3
  • Bitrates for music approximately 500 to 900 kbps rates (similar to other lossless codecs), depending on genre
  • Embedded mp3 track and the mp3HD file share the same id3 metadata
  • Encoding parameters (e.g. bit rate), ancillary data and meta data of embedded mp3 track are under control
