Thus MPEG-4 HE-AAC is efficient version of AAC-LC . So is called as MPEG-4 High Efficiency-Advanced Audio Coding. For better compression and higher audio quality PS tool is implemented. Where PS represents the Parametric Stereo. So it is used to compress the audio more than 30 percent. Which results MPEG-4 HE-AAC Version 2.
