Hi there,
I'm preparing an experiment in which participants are supposed to listen to a soundfile for 30 min. They should listen to the whole audiofile, so I thought it would be a good idea to disable the continue button. How do I do that or is there a better way to make them liten to the whole audio?
Thanks!!

Use the sound file in the BackSound field of the item. Keep in mind that MediaLab will play files in the Backsounds field their completion. This allows for files in the Backsounds field to play through multiple items if you care to structure things that way. To have MediaLab wait for the duration of the sound file and then automatically proceed, use the duration parameter for the questionnaire item using the Backsounds field and specify the length of the sound clip in seconds. For example, type (d30) in the Parameter(s) field of the questionnaire item to play the file in the Backsounds field for 30 seconds. To play a 30 minute clip, use (d3600) in the parameters field of the item.
