  MPEG-4 AAC Main Profile
  
     <compression, standard, algorithm> A successor of
     MP3 allowing transparent coding at data rates of 70-75% of
     that of MP3.  It is very different from MP3, only used
     MDCT, no subband coding.  It is much more complex that
     MP3 and MPEG-2 AAC Low Profile.
