A small exhibition needs a repeating background track, and I am working out the preparation steps. I need to think about the transition between the final section and the opening passage. It seems useful to list boundary issues separately from anything noticeable within the passage. I bookmarked remove suno artifacts while gathering possible references for the second question. I would begin by finding a suitable loop region and listening to its transition several times. The playback system also needs checking because the actual player may introduce a gap between files. Only after that would I decide whether an internal texture deserves a separate experiment. Keeping the original available should help us judge whether a trial preserves the intended atmosphere. The final check would use the actual speakers and the expected exhibition playback level. What would you check first when preparing this kind of continuous playback?
