CAF Audio Format

CAF Converter

The CAF format is a type of audio file developed by Apple, and the name is short for Core Audio File. As well as audio, CAF files can contain metadata like text annotations, markers and channel layouts. This makes CAF similar to the WAV format. However, WAV files have a size limit of 4GB, while CAF files don’t have this limit, meaning they can contain audio data with longer playback durations. CAF files can also store different audio formats, not just one type like MP3, and can have multiple audio channels.

CAF is an Apple proprietary format, and it’s designed specifically for devices using iOS and OS X. If you’re using an Apple device, you can open CAF files using the free Apple QuickTime Player and GarageBand apps, or the paid Final Cut Pro and Logic Pro apps. If you don’t have an Apple device, you can open CAF files for free with VLC Media Player or Audacity. There are also some WAV editors that support CAF audio.

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.
