Advanced Audio Coding (AAC) is a digital audio file format that reduces file size via lossy compression. Its primary uses are digital TV, digital radio, and Internet streaming. It is the standard audio format for iOS, YouTube, Nintendo, and Playstation. ISO/IEC designated the AAC codec as an improvement to MP3, due its ability to compress file size more efficiently while providing quality similar to uncompressed audio.
Developed by: ISO/IEC MPEG Audio Committee
Initial Release: 1997
