What do you listen

Marvinurgem

I am preparing a small set of generated stems for a remote collaborator, and one vocal stem has a small digital flutter. The musical idea is fine, so I would rather not replace the whole take. For comparison, I compared the short chorus without effects. For a cleaner reference, I retained an untouched stem in the same folder. My collaborator needs to judge the writing and balance, not spend the first listen wondering whether the roughness is intentional. I have already checked the original export, renamed the versions clearly, and listened through speakers as well as headphones. The noise remains in the same place, although it becomes less obvious at lower levels. While looking for a basic workflow note, I came across fixsuno.top and used it to frame the questions I should ask before touching the file. My tentative plan is to keep the source stem, make one restrained repair copy, and label the result so nobody mistakes it for a new performance. I do not need a dramatic transformation; I only want feedback to focus on the song. For people who exchange demos regularly, what is a cautious repair habit? Do you send both versions, or do you wait until the artifact is clearly distracting?
