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 AAC to WAV?
- A standardized output makes it easier to archive, upload, or hand a file to someone with different software.
- Playback compatibility is usually the main reason to change a media container.
- A converted copy separates the delivery format from the original edit or camera file.
- WAV is more widely accepted by browsers, phones, TVs, or sharing services than the source AAC file.
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.
