I think it's a big deal.
Yeah going out with statements like "loudness war is over" is a bit too much too soon- but dont let that fool you in thinking that what Katz or iTunes are aiming for is a lost, irrelevant cause.
the WAR is going on for decades now, and is still being fought hard. we are speaking here as educated and informed mastering and audio engineers. usually the guys pushing for more volume are the artists and their producers, along with AnR guys and record companies.
listening to
modern music i think it's fair to say that more volume comes at the expense of quality. even with out comparing to old 70's music. Nirvana's 'Nevermind' sounds amazing!- but in todays
standard it's soooooooo quiet!
It's up to us, those who care about music, LOVE dynamic range, and understand the science behind it with the pros and cons of volume, to EDUCATE the rest of the music industry, artists and producers first, and use what itunes have done as leverage to actually end the war, and make them understand that louder will not in fact sound better, and will not sell more any longer.
it's a start, but it's a promising start. more and more audio distribution companies are starting to realize this, the general public is starting to wake up, and we mastering engineers have to fight for it.
Maybe in 2020, we'll look back and say - THIS was the moment, from here we started fixing things.
I hope so.
