AAC file format information

Full NameAdvanced Audio Coding
Mime Typeaudio/aac

An AAC file is a highly efficient and modern format for storing audio data. Its intention is to improve on existing formats such as MP3 by introducing a more effective compression algorithm while at the same time preserving the quality of the original audio data.

This improved efficiency has meant the AAC format has become widely adopted within the fields of digital music, audio books, and other online audio services. The compression outperforms other comparable audio formats while providing similar quality at reduced bit rates.

The emergence of AAC as an alternative audio file format, along with its adoption by many big names in the industry, has meant support for the format in both the audio editing and playback arenas has gained significant traction.
