HE-AAC (High efficiency Advanced Audio Coding) decoder is an advanced version of AAC-LC (Low Complexity) decoder.
HE-AAC version 1 (HE-AAC v1) uses Spectral Band Replication (SBR) technology to enhance compression efficiency in frequency domain and HE-AAC version 2 (HE-AAC v2) which is an extension of version 1. It uses SBR with Parametric Stereo (PS) technology to enhance compression efficiency in stereo signal.
