AAC File Extension

Have a problem opening a .AAC file? We collect information about file formats and can explain what AAC files are. Additionally we recommend software suitable for opening or converting such files.

What is the .AAC file type?

The AAC file extension stands for Advanced Audio Coding format used by Apple Inc. and other developers for efficient compression and distribution of digital music. It allows significantly reducing size of audio files while preserving good sound quality.

Promoted as the successor of the MP3 file format, AAC provides a series of significant enhancements in comparison with it. AAC files have better sound quality, higher coding efficiency for stationary and transient signals, multi-channel support and improved handling of sample frequencies.

The .aac files are often packed inside of an MP4 container to support tagging and identification features. The AAC file format has been certified by ISO/IEC committees as part of the MPEG-2 and MPEG-4 standard.

Even though .aac files are commonly associated with iPhones, iPods, and iTunes, this audio format does not belong to Apple. It was developed by several independent companies in 1997 and can be opened on multiple Apple as well as non-Apple devices.
