Why convert OGG to M4A?
- 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.
- M4A is more appropriate for the target application, device, or delivery channel than OGG.
- Compatibility is the main reason to convert when another person or service cannot open the source.
Will quality change?
Lossy M4A output reduces file size by discarding some audio information. Use the original master for further editing. Keep the source if you may need to adjust the conversion later.
