High-Efficiency Advanced Audio Coding (HE-AAC) is a lossy audio compression format that is used to compress digital audio data. It is an extension of the Advanced Audio Coding (AAC) standard and is well-suited for mobile telephony and streaming applications. HE-AAC is known for its ability to deliver high-quality audio at low bit rates.
