Why is it that after its mastered its called the premaster CD ?
The mastering engineer takes the final mixes and matches the sound of all the tracks and levels between tracks and any thing else that needs to be done to “sweeten” the tracks before being burnt to the “premaster CD”. Its called this because the true master is made from this premaster CD and is called the “glass master” which is the CD which all the copies are pressed from in a large mass production plant.
