Convert M4B to AIFF

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.

AIFF stands for Audio Interchange File Format, a standard format for storing high-quality audio data used in professional audio and video applications. Introduced by Apple in 1988, AIFF files are uncompressed and lossless, ensuring pristine audio reproduction. Primarily utilized in audio software, digital workstations, and sound engineering, AIFF files maintain original sound quality, making them ideal for editing and mastering. Despite their large file size, their superior audio fidelity is highly valued in professional settings.
