O que é um arquivo M4B?
An M4B file is an audiobook file saved in the MPEG-4 format and typically used by Apple Books and iTunes. It stores spoken audio encoded with Advanced Audio Coding (AAC) compression, which reduces file size while maintaining clear sound quality. M4B files are similar to M4A audio files but include additional features designed for audiobooks, such as chapter markers and the ability to remember playback position.
Mais informações
M4B files are commonly distributed through Apple's audiobook platforms and are often protected by FairPlay digital rights management (DRM). DRM protection restricts playback to authorized devices and accounts.
For example, if a user purchases M4B files via Apple, they can only play them with Apple Books, iTunes, or other Apple software linked to the user's account. However, unprotected M4B files, such as those created by users or distributed freely, can be played by any media player that supports the MPEG-4 audio format.
Como abrir um arquivo M4B
You can open M4B files with various programs, including Microsoft Windows Media Player, Apple Books, and VideoLAN VLC media player. However, you can only open a copy-protected M4B file with software linked to the account that purchased it.
