AAC Audio Format

AAC Converter

AAC is one of the most common formats for digital music, in a large part because it is the default format for Apple devices and the iTunes program, as well as some Sony and Nintendo devices. AAC is short for Advanced Audio Coding. It was developed in 1997 and is now an open standard recognised by ISO, the International Organization for Standardization.

Like MP3, the AAC file format uses lossy compression. With both formats there is some loss of audio quality to create smaller file sizes that let users to store and share music more easily. However, with both MP3 and AAC, most listeners cannot hear this loss of quality. AAC also generally produces higher quality sound than MP3. As AAC is a widely used open standard format for digital music, you can play AAC audio tracks with almost all media players, including Apple Music, Windows Media Player, VLC, and Adobe Audition.

MP3 Audio Format

MP3 Converter

MP3 is the most common format for storing and playing digital music. It’s short for ‘MPEG-1 Audio Layer 3’, and it was developed in the early 1990s as a way of compressing audio to create smaller files that could be easily shared and stored without losing too much sound quality.

MP3 is a universal format maintained by the International Office for Standardization (ISO). MP3 tracks will play on almost any device and with most media players, including Windows Media Player and Apple Music. Digital music took off in the 1990s and 2000s, and many users used media players to ‘rip’ CDs, or download tracks from sites like Napster, turning MP3 into the most common audio format. Because MP3 uses ‘lossy’ compression that can’t be reversed, some music listeners prefer to use other formats such as FLAC, even if the file sizes are bigger.
