About Waveform Audio File Format
Lossless, straightforward to edit, and ideal for production, mastering, and archival work. Very large files compared with compressed audio; metadata and codec support vary by application.
Format referenceWhy convert AC3 to WAV?
- 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.
- WAV is more appropriate for the target application, device, or delivery channel than AC3.
- Compatibility is the main reason to convert when another person or service cannot open the source.
Will quality change?
The WAV output uses a lossless container, but it cannot recover detail already lost in a compressed AC3. File size usually increases. Keep the source if you may need to adjust the conversion later.
