CAF is Apple's professional audio container, native to macOS Core Audio. WMA (Windows Media Audio) is Microsoft's audio codec family within the ASF container — WMA Standard (lossy), WMA Pro (multichannel), and WMA Lossless. Converting CAF to WMA bridges Apple's professional audio with the Windows Media ecosystem.
This conversion decodes the CAF audio to PCM and re-encodes using Microsoft's WMA codec. From lossless CAF sources (PCM/ALAC), the WMA output benefits from perfect source material.
Some corporate Windows environments and legacy media systems require WMA format. Windows Media Player integrates most smoothly with WMA files. Converting CAF to WMA enables macOS professional recordings to enter Windows-standardized distribution channels.
WMA Lossless provides bit-perfect audio in Microsoft's ecosystem, making it an option for lossless delivery to Windows-based facilities.
FFmpeg reads the CAF container, decodes to PCM, and encodes using wmav2 (WMA Standard) or WMA Lossless into an ASF container. From lossless CAF sources, the encoding has optimal source quality. WMA Standard bitrates range from 48 to 192 kbps. Basic metadata can be added as ASF attributes.
WMA Standard at 128-192 kbps from lossless CAF sources produces good quality. WMA Lossless preserves every sample for bit-perfect delivery. WMA Standard is less efficient than AAC at equivalent bitrates.
