An Embedded wave allows you to add small sound into the project without having external files.
This is great for Actions – sound on button click etc… Don’t put music there – it will make the project file very big. The big files should stay external!
How to use it? Just load some wave, give it a name (without extension) and then use this name instead of the path in your sound action or PlayWave script commands.
