If you want to master a song you've previously released on your Rapchat profile, here's what you need to do:
Access the song menu: Press the three-dot menu next to the song you want to master.
Choose "Master": Select "Master" from the menu options.
Select the auto-mastering filter: Choose the auto-mastering filter you'd like to use from the options available.
Save the master: Press "Save" to complete the mastering process.
It's important to choose your auto-mastering filter carefully, as you can only master a track once. By following these steps, you should be able to master your previously released song on Rapchat.
