After dinner I returned to a short Suno demo that had a useful chorus idea. On headphones, a faint buzzing layer appeared whenever the singer held a note. It was noticeable only now and then, yet once I noticed it I could not ignore it. For a moment, I asked myself whether it was a monitoring issue. I saved the spot. Before doing anything, I monitored the repeated bar on another device. I want to share 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 basic restoration methods, 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 reliable first step for this kind of issue? I am especially curious how you decide whether an odd texture is part of the performance before changing anything.
