High-Efficiency Advanced Audio Coding is an audio coding format for lossy data compression of digital audio defined as an MPEG-4 Audio profile in ISO/IEC 14496–3. It is an extension of Low Complexity AAC optimized for low-bitrate applications such as streaming audio. The usage profile HE-AAC v1 uses spectral band replication to enhance the modified discrete cosine transform compression efficiency in the frequency domain. The usage profile HE-AAC v2 couples SBR with Parametric Stereo to further enhance the compression efficiency of stereo signals.
HE-AAC is used in digital radio standards like HD Radio, DAB+ and Digital Radio Mondiale.
