Convert OGA to M4B

An OGA file, short for Ogg Vorbis Audio, is a multimedia file format developed by the Xiph.Org Foundation. It is designed primarily for efficiently streaming and compressing high-quality audio. Originating in the early 2000s, Ogg Vorbis was intended as an open-source alternative to proprietary formats like MP3. The OGA file extension signifies a container format that can encapsulate audio data encoded with the Vorbis codec, providing superior sound quality and smaller file sizes, making it a preferred choice for various multimedia applications.

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.
