sound at the same time as multiple word stim (case 5275)

[ffimel]

Hi

I am running a study that requires participants to complete a serial recall task as they listen to an audio file

the audio lasts for 20 seconds and needs to be played over 8 single numbers (1 seconds each) with a short interval between each (250msec).

Is it possible for the complete audio file to be played over each different stim?

Thanks
