Mastering a master
Hi, Got a question. Can you Master a Master copy again, or do you need the mixed version. A friend has given me a mastered copy of her songs and wants them mastered again (to sound better than what she has now). She does not have the original mixed down versions. Does this cause a problem with levels, distortion and other things that i may not know. Or can this be done. And how do I go about it? Thanks Lou.
