Follow the easy steps below:

1. Add file: click "File->Import PowerPoint", make sure "Import links" checked (for "Quickly import, only import 10 pages to initial preview", of course, you can customize page range to import for previewing);

2. Design Setting: set "Tool Bar->Enable Sound->Enable", you can also add background music, then "Apply Change";

3. Output: Click "Convert to Flipping Book" to choose output format from *.html, *.zip, *.exe, or burn to CD, and then click "Convert" to output flipbook with page-flipping sound inserted.
