What is a AAC file?

An AAC file is an audio file similar to an .MP3 file but compressed with Advanced Audio Coding (AAC), a lossy digital audio compression standard. The lossy compression maintains quality nearly indistinguishable from the original audio source, making it optimal for compressing music data.

Various companies, including Nokia, LG Electronics, Dolby, Sony, Panasonic, and NEC, develop the AAC standard. They initially released it in 1997, and the International Organization for Standardization (ISO) and the International Electrotechnical Commission[3] (IEC) standardized it.

AAC offers several performance improvements over MP3. Some features include a higher coding efficiency for stationary and transient signals, a simpler filterbank, and better handling of frequencies above 16 kHz.

Various devices and apps utilize AAC as their default method for encoding audio. Examples include iPhone, Nintendo 3DS, Apple iTunes, Apple Music, the iTunes Music Store, and PlayStation 4.

NOTE: While the .aac extension is sometimes used for AAC-encoded files, they are often saved with an .M4A file extension.

How do I open a AAC file?

You can open an AAC file with various audio players, including Microsoft Groove Music (bundled with Windows) and Apple Music (macOS) (bundled with macOS).

You can also play AAC files with Nullsoft Winamp (Windows), VideoLAN VLC media player (multiplatform), Adobe Audition (multiplatform), and MPlayer (multiplatform).
