Mastering can do a lot for your song but it really can’t fix it. This has to do with several factors. For starters, a mastering engineer deals with a track on macro levels. It can not effectively fix issues on a micro level. As you can probably imagine, mastering can’t add delays to just your vocal track. Despite the skills and experience of a mastering engineer, getting a good result naturally also depends on the material they have to work with.
