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.
Advanced Audio Coding (AAC) is a digital audio file format designed to provide superior sound quality and compression efficiency compared to older formats like MP3. Developed in the late 1990s by a consortium of companies, including Fraunhofer IIS, Dolby, and Sony, AAC has become the standard audio format for various platforms, including Apple's iTunes and YouTube. It is widely used in streaming, broadcasting, and multimedia applications due to its ability to deliver high-fidelity audio at lower bit rates, making it ideal for bandwidth-constrained environments.
