Core Audio Format (.caf)

The CAF (Core Audio Format) file extension is a flexible, high-performance file format for storing audio data developed by Apple Inc. and introduced with Mac OS X 10.4 to the market. It supports a wide range of audio formats, enabling efficient audio recording, editing, and playback. CAF files are widely used in professional audio environments due to their support for 64-bit audio file offsets, allowing them to accommodate audio files of virtually unlimited size, making them ideal for long recordings and high-quality sound samples. They also support metadata, enabling the storage of additional information about the audio content.

MPEG-4 Audiobook (.m4b)

M4B, which stands for MPEG-4 Audiobook, is a file extension specifically used for audiobooks. It falls under the MPEG-4 Part 14 container format, derived from Apple's implementation of MPEG-4 multimedia. M4B files typically support metadata and chapters, enabling users to bookmark their place in an audiobook and resume listening later. Unlike standard MP3 files, M4B files can incorporate Digital Rights Management (DRM) for copyright protection. Originating from the early 2000s, the M4B format gained popularity with the rise of Apple's iTunes Store and its focus on digital audiobook distribution. Today, M4B remains a standard for digital audiobooks, known for its advanced features and compatibility with various devices.
