Creating Custom Ringtone for MacBook Pro

macOS & Mac Apps

I am trying to add a custom ringtone to the MacBook Pro for the incoming facetime calls. I know you have to do some terminal commands and such, which I have done in the past. Does anyone know how to create a custom ringtone for the mac and add it to the ringtones for facetime calls for Mac? I already have it in M4R format.
