Audio issues

sbashyam — Thu, 07 Sep 2023 01:24:39 GMT

Hi Dave,

In my current study, I have set up some images appearing in a random order. The participant is required to count the number of animals on screen and enter a value. I was able to write the code for this and it works. However, I am having trouble adding audio to the trials. At the display of every image, I want two audio files to be played (both included in the folder attached below) - first "what_card.wav" and then "CanUCount.wav". My issue is that when I try to make the </sound> category, I am given an error about double quotes, even though I have double quotes in my syntax.

Could you please help me out?

Thank you Dave! Can you also tell me how I can play the audios for each trial?

You display <sound> stimuli just like any other type of stimulus, be it <text>, <picture>, <shape> or <video>. Add the sound stimulus to a <trial>'s /stimulustimes or -frames, at the time you want it played.

It's not entirely clear when, exactly, you want those audios played, but I'm guessing you want something like this:

[code]<sound whats_card>
/ items = ("what_card.wav")
/ playthrough = true
</sound>

<sound can_u_count>
/ items = ("CanUCount.wav")
/ playthrough = true
</sound>
[/code]

being the two audios, and the trial playing those back one after the other before allowing the subject to continue.

[code]<trial showpicture>
/ stimulustimes = [0=stimuli_display, whats_card; 2000=can_u_count; 5000=continue]
/ validresponse = (continue)
</trial>[/code]

Change the timings as needed if you want a longer or shorter pause between the two sounds.

Do you see how these double-quotes look kind of curly?

These are simply the wrong quote characters (don't copy & paste from word processors or the like). You need to use plain double-quotes, i.e.

[code]<sound whats_card>
/ items = ("what_card.wav")
/ playthrough = true
</sound>[/code]
