How do I play a sound?
On the left side of ArtStudio is the layer toolbar. One of the buttons will display the Layer Properties. Every layer can play a sound. On the Start & Finish tab you can select a .wav or .mp3 file. Be careful, sound files can be very large which could greatly increase the size of your artwork file.
Currently, only .wav & .mp3 files are supported. There are a lot of sites on the internet where you can download them. Here's a good place to start.
