Bob Ludwig er en nestor innen mastering.Meget bra. Bør leses. 
"..As a mastering engineer, people sometimes blame us for things we have no control over. Mixers themselves have found that A&R departments, and certain record company executives, wouldnt approve their mixes unless they were already that loud. So the mixers, in self defense, started premastering stuff before they send it to me, and pre-squishing it and compressing it. And then we get it, and everybody in the band is used to this by now, and if you dont give them something back thats at least that loud, they think youre not very good. Its a very deadly situation"
