Opus, associated with Opus Audio, is an open, royalty-free audio codec designed for high-quality voice and music streaming. Introduced by the Internet Engineering Task Force (IETF) in 2012, it adapts seamlessly to various applications like VoIP, videoconferencing, in-game chat, and live music performances. Known for its versatility, low latency, and high compression efficiency, Opus is widely adopted in modern communication platforms and web applications, making it a cornerstone in contemporary audio technology.
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.
