When to Convert
Common scenarios where this conversion is useful
Cross-platform sharing from macOS to Windows
AIFF files recorded on macOS cannot be played natively on Windows. Convert AIFF to WMA to share audio with Windows users who rely on Windows Media Player.
Xbox game soundtrack integration
Xbox does not support AIFF but supports WMA for custom soundtracks. Convert AIFF recordings or music to WMA for use in Xbox media libraries and gaming soundtracks.
Reducing file size from lossless AIFF
AIFF files are very large. Converting to WMA dramatically reduces file size while maintaining acceptable audio quality for distribution and portable storage on Windows devices.
Windows enterprise media systems
Corporate audio systems and Windows-based telephony platforms often require WMA. Convert AIFF source audio from macOS recording sessions to WMA for deployment in these enterprise environments.
