Convert MP3 to M4B

MP3, short for MPEG Audio Layer 3, is a digital audio coding format that revolutionized music storage and distribution. Developed by the Moving Picture Experts Group (MPEG), it was first introduced in the early 1990s. Its primary advantage lies in its ability to compress audio files significantly without major loss in sound quality, making it ideal for efficient storage and transmission over the internet. MP3 files are widely used for music playback on various digital devices, including computers, smartphones, and portable media players, due to their balance of compression efficiency and sound fidelity.

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.
