About M4B to WMA Conversion
WMA (Windows Media Audio) is Microsoft's proprietary codec. Converting M4B audiobooks to WMA moves content from Apple's ecosystem to Microsoft's. WMA audiobooks play in Windows Media Player and on older Zune devices. Windows does not have a native M4B-aware audiobook player like Apple Books, so WMA provides a familiar format for Windows-based audiobook listening through Windows Media Player's library.
Why Convert M4B to WMA?
Windows users without iTunes may prefer WMA for audiobook listening through Windows Media Player. Older Windows CE/Mobile devices and Zune players support WMA natively. Some Windows-based digital library systems (OverDrive's older platform) used WMA for audiobook downloads. DLNA servers may transcode for devices that prefer WMA.
Common Use Cases
- Playing audiobooks through Windows Media Player on PCs without iTunes
- Loading audiobooks onto Zune or older Windows Phone devices
- Distributing audiobook content through Windows-based digital library systems
- Streaming audiobooks via DLNA to devices that prefer WMA format
