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 MPEG to WAV?
- 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 MPEG.
- Compatibility is the main reason to convert when another person or service cannot open the source.
- The new format may support a feature the source container does not.
Will quality change?
The decoded samples are stored without another lossy encoder. Check metadata and channel layout after conversion. Check a sample before processing a large batch.
