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

MPEG 4 Audio (M4A) compresses and encodes audio files by using one of two coder-decoder algorithms: Advanced Audio Coding (AAC) or Apple Lossless Audio Codec (ALAC). M4A files are smaller in size while simultaneously better in quality than MP3 files, with which it shares the most similarities, in comparison to all other audio file formats.
M4A files open in most well-known, audio-playback programs, including iTunes, QuickTime, and Windows Media Player. For Apple users, iTunes is the default program to open M4A files. For Windows users, the default program is Windows Media Player. Users can also preview M4A files by highlighting the file and pressing the spacebar.
