True, it is less of an issue for certain genres than others; but even within those, think of the titles that sound excellent (well-mastered) and those that are just average. Or those that sound "loud", and those you have to crank up a bit to hear.
TMU wants to educate engineers...and consumers...to the issue; in this case, the hope is transparency will breed contempt! To that end, they also want to institute DR stickers...that would identify the Dynamic Range of a title; in hopes that might also discourage crappy-sounding releases. It's a worthy cause IMO; especially if we don't all want to end up listening to mp3s.

The first graph shows a 16bit/44khz sampling rate CD. There is nothing "maxed out" in it, it just shows that there is no information above 22khz. All CD's are brick-walled at 22 khz (yes,even the Blue Note XRCD's) which is a function of the Nyquist-Shannon Sampling Theorem and has nothing to do whatsoever with any type of compression, dynamic or otherwise. In fact, a 22khz brick-walled CD still has the potential of over 90dB of dynamic range, whereas vinyl has maybe 60. (This is not meant to start a vinyl vs. digital debate; these are just facts). Also, on the first graph where all the red is clumped together- that is not compression, but rather just very busy passages. The second Audacity graph shows a recording that has frequencies that extend well up to 40khz. This tells me this is a hi-rez recording and has a sampling rate of 88khz or above. The Loudness Wars are, to put it simply, boosting the loudness of the quiet passages and slightly cutting the loudest passages so everything comes across pretty much equally loud: this is called dynamic compression. In other words, they take the soul out of the music. They did this so the all the music can be better heard on your car radio, your boom-box, cheap headphones, Best Buy systems, etc. The problem is it really sucks for people like us who have more revealing systems. The good news is most of the Loudness bullshit is pretty much limited to pop and rock. Now, just because you listen to vinyl and you happen to enjoy pop and rock, it doesn't mean you're exempt. If you were to purchase a later vinyl recording of AC/DC or The Red Hot Chili Peppers, your vinyl is also going to suffer from the dynamic range compression. Here's a good read on dynamic compression: The Loudness War Analyzed « Music Machinery Last week I downloaded, from HD Tracks, the new Chieftains album in 24/96. What a disappointment! Even though it has a lot of very high frequency extension, it is unlistenable above 9:00 on my volume knob....too frickin' loud. So even T-Bone Burnett, who produced the album, is caught up in this bullshit. Here is the Audacity spectrum graph of one of the tracks from that album. This is to illustrate that the frequency spectrum graphs have nothing to do with dynamic range compression. [IMG]  [/IMG]
