I am trying to use the same methodology found in http://houdekpetr.cz/!data/papers/Brock%20Balloun%201967.pdf but I am unsure how I should proceed.
Essentially, the experiment had audio recordings playing and over them was a a layer of static. The participant could press a button to reduce the static. The only thing I could think of is to have several files: one audio file containing an excerpt of something uninterrupted and then several files of white noise or static that could be ‘reduced’ or diminished by pressing a key. The key press would end the one noise and go to the next.
Is this possible?
