I am planning a short listening exercise for an audio workshop. The aim is to help participants describe what they hear before they decide which version they prefer, rather than treating every change as an improvement. I have a generated passage in mind as the source material. We would use the same passage in every comparison. A page discussing ai music artifact removal gave me a starting point for the topic, but it does not settle how to structure the exercise. The versions should be presented at comparable listening levels. A first round without labels might encourage independent observations. We should include the untouched source in the set. I would ask about texture, transients and vocal clarity separately. We could repeat the excerpts in a different order and discuss disagreements, since a single preference vote would reveal little about the reasons behind it. What listening criteria would you add to this exercise?
