A. 1. Create animations in Fresco and then export them to a video editing app that supports audio, such as Adobe Premiere Rush, to add sound. 2. Use a separate audio editing software to create your audio track and sync it with your animation in post-production. 3. Explore other animation apps that offer audio support if this feature is essential for your projects.

B. 4. Consider using background music or sound effects from royalty-free sources and add them during the editing phase.
