how to create compilation audio cd?
 

currently I have three wav files. How can I burn them together to be one audio cd? can I do it the DAO way?

I don't see why not. What CD-burning software are you using?

For example, in X-CD-Roast, you can select the .wav files you want to burn, put them in order, and burn straight to disc, or burn to an image first, and then burn the image to disc. The procedure is probably similar in other software.
