MP3 MP3 File Format

Files with .mp3 extension are digitally encoded file formats for audio files that are formally based on the MPEG-1 Audio Layer III or MPEG-2 Audio Layer III. It was developed by the Moving Picture Experts Group (MPEG) that uses Layer 3 audio compression.

AC3 Audio Codec 3

AC3 files are binary in nature and based on the Modified Discrete Cosine Transform (MDCT) which is a lossy compression algorithm. Dolby Laboratories used the MDCT algorithm along with perceptual coding principles to develop the AC-3 audio format. This led to the release of the AC-3 format as the Dolby Digital standard in 1991.
