CAF is definitely an unfamiliar audio format that does not work well with most media players although it is produced by Apple Inc. Therefore, here we will show you how to successfully convert a CAF audio file to common formats, such as MP3, for smooth playback. If you need to convert other audio formats, try MiniTool Video Converter.

What Is a CAF File?

CAF (Core Audio Format) developed by Apple Inc, is an audio container format for storing and manipulating digital audio data. Due to its use of 64-bit file offsets, CAF surpasses the 4 GB limit of file size. Moreover, CAF can be used to save any audio data no matter they are compressed PCM or uncompressed AAC.

Meanwhile, it has a safe and efficient recording and supports many different audio formats, metadata tracks, and more data. It is compatible with Mac OS X 10.4 and higher, while Mac OS X 10.3 needs QuickTime 7 to be installed.

However, this file format cannot be played on many media players or other operating systems such as Windows. Therefore, it is necessary to convert it to a file format with better compatibility, like MP3.
