Core Audio Format (CAF) is Apple’s professional audio container, introduced with Mac OS X Tiger. Unlike WAV and AIFF, which are effectively capped at 4 GB, a CAF file has no practical size limit, so it can hold hours of high-resolution multichannel audio in one piece. CAF is a container rather than a codec: the audio inside may be uncompressed PCM, Apple Lossless, AAC, or several other encodings.

 

How to open a CAF file?

On macOS, CAF opens in QuickTime Player, the Music app, Logic Pro, and GarageBand without any extra software.

 

On Windows and Linux, use VLC media player or Audacity, and FFmpeg for batch conversion. Because CAF is largely an Apple-only format, converting it makes sharing far easier — try our CAF to MP3 or CAF to WAV tool.

iPhone Audio is an M4A file encoded for Apple iPhone, containing AAC audio in an MPEG-4 container. AAC delivers noticeably better sound than MP3 at the same bitrate, which is why Apple adopted it as the default for the iTunes Store and for music on iOS. Choosing this preset produces a file the iPhone plays natively, with artwork and track tags intact.

 

How to open an iPhone Audio file?

On the phone, the file plays straight away in the Music, Voice Memos, or Files app — nothing extra is required.

 

To get the file onto the device, sync it through iTunes, the Finder on macOS, or iCloud Drive. On a computer the same M4A opens in iTunes, the Apple Music app, Windows Media Player, VLC media player, and every major web browser. For maximum compatibility with older devices, convert it with our M4A to MP3 tool.
