  Roviden es tomoren a lenyeg, ha vagod az andolt:

  "The AAC format was designed to be an improvement over MP3 in the following aspects:

  More sample frequencies (from 8 kHz to 96 kHz) than MP3 (16 kHz to 48 kHz)
  Up to 48 channels (MP3 supports up to two channels in MPEG-1 mode and up to 5.1 channels in MPEG-2 mode)
  Arbitrary bit-rates and variable frame length. Standardized constant bit rate with bit reservoir.
  Higher efficiency and simpler filterbank (rather than MP3's hybrid coding, AAC uses a pure MDCT)
  Higher coding efficiency for stationary signals (AAC uses a blocksize of 1024 or 960 samples, allowing more efficient coding than MP3's 576 sample blocks)
  Higher coding accuracy for transient signals (AAC uses a blocksize of 128 or 120 samples, allowing more accurate coding than MP3's 192 sample blocks)
  Can use Kaiser-Bessel derived window function to eliminate spectral leakage at the expense of widening the main lobe
  Much better handling of audio frequencies above 16 kHz
  More flexible joint stereo (different methods can be used in different frequency ranges)
  Adds additional modules (tools) to increase compression efficiency: TNS, Backwards Prediction, PNS etc. These modules can be combined to constitute different encoding profiles."
