we’ve been reading the manual and look throught this forum but we did not find the answer.
We are trying to make a startle reflex experience. We need to show a picture for 6 seconds, and, while the picture is still at the screen, we would like to have a very short sound, randomly, between 3 and 5 seconds after the begining of the picture.
How to mix a picture and a soundfile? We found how to place a picture while a sound is playing, but we would like to do the opposite. A brief sound while a picture is showed.
