There has been much critisising of Metallica's latest release, Death Magnetic, for being too loud and mixed badly, and suggestion that the Guitar Hero 3 version they released for download over the PSN store is superior...
So I decided to find out for myself.
First off, there is this;

Now that says three things to me; 1) the volume on both versions is the same. 2) the CD version sounds muffled and "muddy", and 3) the GH3 version sounds clean, clear with lots of top end clarity.
So, after a hunt, I got hold of a full-fat lossless FLAC copy of the GH3 album (aswell as a compressed MP3 version) and pit them against my own CD version, that I ripped to 320k MP3 (purely cos it's easier to compare this way.
I did this in several places - I placed an MP3 192k rip from my own CD onto my ipod, aswell as the compressed GH3 rip (which is variable bit rate, between 160 and 192k). I put it in my van and tried it out (for specs, my ipod plays to my van stereo using 3.5 stereo jack from the headphone on the ipod to the AUX input on my stereo, ipod volume set to max)
Normally, most music is played between vol level 16-18, with 20 being if I want to crank it.
The CD rip @ vol 18 was LOUD! I could hear clipping in it on the really heavy sections, and it sounded sharp (especially the cymbals). Moving up to vol 20, bits of it made me wince slightly as it was incredibly "hard" on the ears.
So I tried the GH3 MP3's - OMG! What a difference!

It has significantly quieter - to achieve the same audible volume as vol 20 with the CD rip, I had to crack the stereo to 30! Even then it wasn't as loud.
Quality wise it actually sounded better. Not as sharp, not as hard on the ears, the mix sounded better, although it didn't sound like it had an EQ on it. Even at almost the same volume as the CD rip, it sounded nicer to listen to.
So, back in the house and testing on the PC.
I loaded both versions into iTunes. I have iTunes set to near max volume (my hifi is at half volume) and the EQ set to ROCK, with the high end boosted just a tiny bit.
First, the CD Rip. Again VERY LOUD!!!! The clipping in the heavy sections was still present, but it sounded better than my van stereo from my ipod, as it wasn't as hard on the ears, and was nice and clear.
So, I tried the VBR GH3 MP3's - again, half the volume of the CD Rip, but surprisingly, it sounded muffled and flat! Nowhere near as nice sounding as the CD Rip. The clarity was gone, the low end was almost still there, but the attack of the drums was lost as was the cymbals.
Strange!
So, onto test number three!
Lossless Flac Vs CD rip MP3 320
This was done using VLC (so I could play the FLAC) and with no plugins or EQ settings. Volume set to 100% in VLC, hifi still the same
Again, huge difference between the two. Volume is 1st, with the FLAC at half the volume of the CD Rip (same vol level as the GH3 Mp3's). And the same result happened as it did with the iTunes test - the FLAC copy didn't sound as nice as the MP3. The "scoop" EQ effect was missing, it sounded flat and dull, and somewhat muffled. Vocals sounded low in the mix, attack from the drums and cymbals had gone. The only two negatives for the CD rip MP3 320 was that it was a) still too loud, and b) still getting clipping in the heavy sections.
Onto test number 4! - iTunes, CD rip MP3 @ 192 vs GH3 MP3 VBR (160-192)
In this test EQ was turned off, and I used the iTunes vol adjuster to change the volume of each set of tracks - CD rip was lowered -90% and GH3 was raised +100%. This gave them thereabouts the equivelent(sp) volume level.
Same result as before. CD version scored over the GH3 version. Clearer, more attack, brighter highs, tiny bit sharper, and fuller heavy sections, and the clipping was reduced to almost non-existent. The GH3 version still sounded flat, dull and muffled.
LAST TEST!
I loaded a CD Rip MP3-320 and a FLAC track into WavePad to visually look at the music.
Here's how they look;
This is the 320 MP3 CD Rip
And the FLAC lossless;
Look at the difference!
Also, Wavepad has a usefull stereo volume indicator at the bottom to show whats happening, and this is the result;
MP3 volume indicator
FLAC volume indicator
There is a HUGE difference in volume. Throughout the whole track it rarely ever dips below the red when playing the MP3, and the flac never gets NEAR the red during it's whole play!
But what I still don't get is why people are saying the GH3 version sounds better than the CD, when, if you take out the loudness of the CD, the CD has a better overall sound, and whats more odd is how the video I posted at the top (which I didn't make BTW) appears to be back to front - muffled sound attributed to CD and clear sound attributed to GH3 when in all the tests I did, the opposite was true....
Thoughts?
