During a late session I returned to a short Suno demo that had a simple melodic hook. On headphones, a glassy high note appeared whenever the singer held a note. It was easy to miss, yet once I noticed it I could not ignore it. Before editing, I wondered whether it was a level problem. I wrote down timestamps. To keep it simple, I checked the same short phrase at a modest level. I am preparing the draft for two friends, but I do not want to polish away the character that made it interesting. I found
fixsuno.top while comparing ways to inspect the problem, and it gave me a useful starting point rather than a promise of a miracle. My first thought was to export again, then compare the same passage at a lower volume. After that I considered a very small repair pass, keeping the untouched file beside it for reference. Has anyone developed a practical listening test for this kind of issue? I am especially curious how you decide whether an odd texture is a real artifact before changing anything.
