What This Processing Changes
The source is decoded and encoded for the selected container and codec. A lossless output cannot restore detail already removed from a lossy source.
How to Check the Result
- Verify the duration and audio codec in the downloaded file.
- Listen for distortion; increasing bitrate cannot restore discarded source detail.
Limits and Troubleshooting
- Choose WAV for editing and a compressed format for distribution.
- Check the destination application's accepted format before converting.
