Hi all,
I'd like to implement a questions where two audio files play at the same time, and the user would have to adjust the audio of one until it is just hearable over the other.
This would imply having a way to adjust the volume of one of the audios, and collecting that as response.
The task/question is for a method of adjustment threshold detection, something similar to shown on the image attached. I've searched the web for an example or something that could help me implementing it but without success. Is this possible to implement in LimeSurvey? Where could I find some tips about doing it?
Thank you.
Best regards

This does not seem to be LimeSurvey related.
