Advanced Audio Coding is designed to be the successor of the MPEG-1 Audio Layer 3, known as MP3 format, which was specified by ISO / IEC in 11172-3 ( MPEG-1 Audio) and 13818-3 ( MPEG-2 Audio). Blind tests in the late 1990s showed that AAC demonstrated greater sound quality and transparency than MP3 for files coded at the same bit rate.
MPEG logo Some well known older (up to 2005) digital media formats and the MPEG standards they use. The Moving Picture Experts Group (MPEG) is an alliance of working groups established jointly by ISO and IEC that sets standards for media coding, including compression coding of audio, video, graphics, and genomic data; and transmission and file formats for various applications.

WinPlay3 was the first real-time MP3 audio player for PCs running Windows, [2] [3] [4] both 16-bit (Windows 3.1) and 32-bit (Windows 95). Prior to this, audio compressed with MP3 had to be decompressed prior to listening. It was released by Fraunhofer IIS ("Institute for Integrated Circuits"), [5] creators of the MP3 format, on September 9 ...
