What is AAC?
Advanced Audio Coding
Fraunhofer, Dolby, Sony, and others
AAC, which stands for Advanced Audio Coding, is a widely used format for audio compression and the most common audio format for Apple devices. The AAC file type was created as a substitute for MP3. Generally, AAC provides better sound quality than MP3 at similar bitrates. Many devices, including Apple and Android, support AAC. But if you want to play your audio collection on another device without iTunes, your best option is to change the format of your files to MP3, which is still used almost everywhere. Check the list below if you’re not sure how to open AAC audio files and which programs support playback of these files.
.aac, .m4a, .m4p, .m4b, .mp4, .3gp
Files with the AAC specifications enable temporal noise shaping, non-uniform sampling, and bitstream reformatting for 16 stereo, 16 mono, 16 low-frequency channels, and 16 annotation channels in a single bitstream. In 1999, the AAC format was included in the MPEG-4 Part 3 format, after which AAC added support for audio object types and permanent noise replacement technology. AAC is currently described in the ISO / IEC 14496-3 standard.

What is MPEG?
Moving Picture Experts Group Phase 1
Moving Picture Experts Group
The MPEG format was created by ISO and IEC experts. Initially, it was designed as a standard for lossy compression of audio and video data. This format was released for the first time in 1993 and is still being developed. To learn more about MPEG specifications and programs that can play MPEG files, consider checking the table below.
In the MPEG file type, MPEG-1 and MPEG-2 codecs are used to compress the video stream, and the audio stream is usually encoded with the MP2 (MPEG-1/2 Audio Layer II) codec. This format doesn’t work with chapters but is suitable for streaming. MPEG was widely used until the beginning of the 2000s but was then almost displaced by MP4. If you’re wondering how to open an MPEG file, look through the list below. These programs all playback MPEGs.
