I am making a short looping animation with a few small movements and no spoken dialogue. I like the mood of the generated music sketch, yet its bright continuous texture distracts from the small actions. I am trying to decide whether to revise the sound, choose another sketch, or leave more silence between events. One description I encountered was suno shimmer but I have not identified what causes the texture in my clip. Do you start by listening against the picture, or listen separately and then check the visual timing? I want the little movements to remain readable without making the whole soundtrack feel empty. The loop will play on a small screen as well as headphones, so I can check both contexts. I would keep the comparison volume consistent and use the same section of animation. How would you test a few alternatives without letting repeated playback hide the original problem?
