What is a M4B file?
M4B is a variation of the M4A format specifically designed for audiobooks and podcasts. It supports bookmarking, meaning you can pause and resume playback from the exact same point — a crucial feature for long audio tracks. M4B also allows chapters and metadata to be embedded.
This format is commonly used by Apple Books and iTunes for audiobook distribution. While technically similar to M4A, its additional features make it ideal for spoken-word content.
