Enable Audio for the Book:
At the top of the section, you will see a toggle switch next to "Enable audio for the book".
Click this switch to turn it ON . This is necessary to activate all other audio options.
Add Background Music:
Below the toggle is the "Background Music" field. This is where you set the track that plays when the flipbook is viewed.
Click "Select Music" to upload an audio file (like an MP3) from your computer, or you might have the option to choose from a library if Crezlo provides one.
Configure Flip Sound:
Next to "Flip Sound" (which is currently unchecked in your image), there should be a checkbox.
Check this box if you want the classic page-turning sound effect to play every time a viewer flips a page in your digital book. If you want a silent, professional experience, leave it unchecked.
Save Your Changes:
Once you have enabled audio, selected your background music, and configured the flip sound, scroll down to the bottom of the right-hand panel.
Click the "Save Settings" button to apply the audio changes to your flipbook.
