Onset delay for playing audio on a slide

[Cognitology]

Hi Mihai,

Am I late and has this been responded to? There are myriad options to get this sorted, from the top of my head:

·         Make the sounds to start at time … ms by just adding milliseconds of silence to the audio files (I used cooledit in the past for this sort of thing – it’s now called adobe audition and I believe there’s a free trial)

·         You could show the same slide at a very fast interval (say 60 Hz) without the subject noticing (i.e. it just refreshes the slide). 

·         So, with the above point, do notice, the fact that you want to show each picture 6 s doesn’t mean that you need to have the duration at 6 s. That means you might as well show a picture for 2 ms, have a wait object and play the sound at time point x.

Hope that helps.

Best,

Michiel

Hello,

 

Can you please tell me how to adopt this strategy for pictures and sounds? I need to present pictures in a random order (6 seconds each) and a brief sound (50 ms) should play between the 2nd and 4th seonds during the picture display. I created a slide, but the sound always plays at the onset of the pictures.

 

(I saw Mr. McFarlane's post about the frequency of this type of question and I tried to find an answer on the internet, but failed.)

 

Thank you very much!

 

Mihai
