I've been following closely this controversial subject and so far, what i'm reading from the mastering guys is that it's not possible so it's nothing but a scam to get naive music peoples.
It makes sense to me, how can a program predict a desirable high peak from one that is not? or how can an automatic program determine the best loudness/peak limiting from the different variety of music styles? how can a program know that some more impact on the bass could be good while some areas of the spectrum should be left alone?
The fact that someone can create a cookie cutter to master everything is like the most ridiculous thing i've ever heard about audio.
If wecould have a plane take off and land by itself, could we trust that it will never fail? Or how about medicine? Would you subject yourself to a quadruple bypass operation by a machine?
I think we will have the ability to do this things first before any template or an online "instant" mastering service can replace the attention to detail a professional mastering engineer brings to the table.
This may sound like a joke to you the guys who are doing this kind of work for a living, but for many new to audio people it could be a real option just because some service offers it.
So if it's scam say it, if not then explain why.
What's your opinion MEs?
