'''High Efficiency AAC''' (aka '''aacPlus'''), is a [[lossy]] data compression scheme for audio streams, and is part of the '''[[MPEG-4]] Part 3''' specification.
 
 
 
HE-AAC combines [[Advanced Audio Coding]] (AAC), [[Spectral Band Replication]] (SBR) and, since version 2 (or Enhanced aacPlus), [[parametric stereo]] (PS). The [[codec]] can operate at very low bitrates and is good for [[internet radio]] streaming.  A 48 kilobit-per-second stream is considered to have higher quality than 128 [[kbit/s]] [[MP3]].
 
 
 
VLC supports HE-AAC through the [[FAAD2]] library.
