Understanding the Audio: AAC 5.1

AAC.5.1 means:

• AAC (Advanced Audio Codec) – common, efficient, compatible with most devices.
• 5.1 channels – six discrete audio channels (left, right, center, surround left, surround right, LFE/subwoofer).
  This gives a surround sound experience, even though AAC is often compressed. Many WEB-DL releases use AAC instead of the original E-AC-3 or Dolby Atmos to save space and improve compatibility.
