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!

This kind of task would be ideal for DirectRT. But if you need to do it in MediaLab, the onset parameter works (I believe) only for question wording--not media. You would need to build in 500ms of silence into your sound file using a sound editor like Audacity (or whatever). Alternatively, you could create a little HTML page that plays the sound file with a 500ms delay and just add that html file as a background. I can elaborate on any of this if it would be useful.
