M4B Audio Format

M4B Converter

The M4B audiobook format was developed by Apple, and the format is also known as an MPEG-4 Audio Book file. M4B files are mostly used for the audio part of the Apple Books application, which is included as standard on iOS and macOS. If you buy an audiobook from the Apple Books store, the downloads are normally in M4B format and are DRM-protected to prevent sharing.

M4B files are containers for both audio and metadata. The audio part of an M4B file is in MPEG-4 format and compressed with AAC encoding to make the file smaller. AAC is the same standard format that Apple uses for digital music in iTunes. M4B is also very similar to Apple’s M4A audio format for podcasts and music; however, because M4B is designed for audiobooks, it supports bookmarks and breaks for each chapter. You can open M4B files with Apple Books, iTunes, VLC and some audiobook players.

WMA Audio Format

WMA Converter

The full name for the WMA format is Windows Media Audio. As the name suggests, it’s an audio format specifically for Windows devices. Microsoft introduced WMA files in 1999 following the popularity of the MP3 format, and two years after the launch of the AAC format for digital music. However, WMA is not as widely used as these two formats.

WMA files generally use lossy compression to make the files smaller. This can mean the audio quality isn’t as high as with some other formats, although lossless versions of WMA are possible if you install newer codecs. Because WMA is a proprietary format, it’s not always compatible with non-Microsoft players or operating systems. However, you can play WMA files with Windows Media Player, Nullsoft Winamp, MPlayer and VLC. You can also use some of these programs, or online tools like Zamzar, to convert WMA files into formats like MP3 or AAC.
