Delay sound

[katevw11]

Hello-

I am trying to use media lab to present a slideshow and auditory stimulus for my research. I need the auditory stimulus to be delayed .5 seconds from the onset of the image. I found the article telling how to do this, however, the procedure listed is not working. When I add the parentheses and command to the end of the auditory file, the file is not recognized and will not work. Is there a different way I need to go about this, or a specific way to enter the parentheses?

Thanks for your help!
