Why convert WAV to AAC?
- AAC is more widely accepted by browsers, phones, TVs, or sharing services than the source WAV file.
- 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.
Will quality change?
Lossy AAC 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.
