What is AAC?

AAC (Advanced Audio Coding) is a modern, lossy audio codec standardized by MPEG that delivers better sound than MP3 at the same bitrate. It supports multiple profiles—LC-AAC for general listening and HE-AAC (v1/v2) for low bitrates using SBR and Parametric Stereo—plus variable or constant bitrate modes. AAC commonly appears in MP4/M4A containers, but raw streams may use the .aac extension. It handles multichannel audio, high sample rates, gapless playback, and rich metadata, making it popular for streaming (HLS/DASH), podcasts, digital radio (DAB+), and music stores. Most platforms—iOS, Android, Windows, macOS, smart TVs, and browsers—play AAC natively. Recommended bitrates: ~96–128 kbps for mobile, 160–256 kbps for high quality, and HE-AAC when bandwidth is limited.
