What to listen forHeadphones help. Listen at a comfortable volume.
Press play, then switch versions. Keep listening from the same moment.
Synthetic vocal edge: consonants that feel hard or plastic.
Metallic brightness around upper vocals and reverb tails.
Fine digital haze that sits over the vocal between words.
The difference may be less noticeable on a phone or weak speakers. Keep the level comfortable and decide whether the vocal sounds cleaner, not simply louder.
Upload, check, then compare. Keep the original close and let your ears decide.

Use your credit, listen to the result, and compare it with the original.
Start with what you hear.
A glassy vocal. A brittle cymbal. A haze over the mix. Focus on the texture that gets in the way of your song.
Metallic shimmer
A glassy or shiny layer around vocals, cymbals, bright synths, and reverb tails.
Robotic vocals
Plastic tone, hard consonants, or a synthetic edge that makes a strong vocal feel detached.
Harsh highs
Piercing hats, brittle upper mids, splashy cymbals, and fast listening fatigue.
Keep the music at the centre.
Cleanup works on the sound of your existing track. It does not rewrite lyrics or rearrange the song, and it cannot guarantee a perfect repair. Compare both versions before deciding.
Cleanup reduces unwanted texture in the source. Mastering adjusts loudness and balance for the final release; it can also make remaining artifacts more obvious.
