Convert M4B to FLAC

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.

FLAC, or Free Lossless Audio Codec, is a widely utilized audio format offering lossless compression, meaning it retains the original audio quality while reducing file size. Originating in 2001, FLAC has become a standard for high-fidelity audio archiving and distribution, favored for its open-source nature, ensuring broad compatibility and extensive support in various software and devices. It is extensively used by audiophiles, musicians, and professionals seeking optimal audio quality without the large file sizes associated with uncompressed formats like WAV.
