Why convert WMA to FLAC?
- The new format may support a feature the source container does not.
- The result can be reviewed without changing the file that other people still use.
- FLAC is more appropriate for the target application, device, or delivery channel than WMA.
- Compatibility is the main reason to convert when another person or service cannot open the source.
Will quality change?
Converting to FLAC is useful for editing or software that expects uncompressed audio; it is not an audio-quality upgrade. Keep the source if you may need to adjust the conversion later.
