Something I saw on another forum which really captured my attention.
 
 
The leaked version of Cyanide.... pretty damn compressed.
 
 
The retail version.
 
Basically a solid bar waveform, meaning about 0dB deviation (if any at all of some sections of what we see in the waveform are anything to go by) in the volume and dynamic range of the audio(err, if someone can explain that more technically than I can, feel free btwBig%20smile).
 
This is another reason I don't want to get this album... it must be one of the loudest (which can clip audio signals more easily, resulting undesirable distortionDead) and most compressed albums ever madeDead

It's a loud track ... it doesn't have extended silent parts or interludes. I don't think that such a condensed view, where the whole track fits one screen, shows whether it's too compressed.

Today I'll buy the album ... I'll post the album gain as soon as I have it in winamp.Smile

^Well I used to use Nero Wave editor.... and I never saw a single song (even some of the most compressed stuff I had like Systematic Chaos... which is pretty damn compresssed) didn't form solid bar wave forms.
 
If you could take the time too (since I have no intentions of purchasing Death Magnetic), could you perhaps use Audacity (which is what I use instead of Nero Wave Editor, so it will help me to see thing in a perspective I'm more used too), and perhaps, compare the wave forms of some of the most compressed albums you own, and compare them to Death Magnetic?

Well, I've listened to the album several times now, and wave analysis or not, at last a Metallica album worth getting. Although interesting in a WTF way, it goes to show that thankfully some weird graph can't really influence my enjoyment of stuff I like.
 
I mean, come on! Is the picture of a wave form really going to be a criterium on which buying an album is based?

The studios have hardware compressor/limiters that allow them to get away with this type of boosting, without distorting - don't try it at home. It may turn out sounding like mud. And to those who said it is not necessary to master, in the mastering thread I put up, that is where this is done.

^I understand the actual recording itself can be compressed to hell without any actual what we perceive as distortion to the signal.
What I meant, was that, a heavily compressed album has the capacity to make the audio signal being sent to your speakers clip much easier than a less compressed album.
You can certainly crank an audio player to full volume with a less compressed album and it probably wont do any harm to the speakers... problem with excessively compressed recordings in the case of Death Magnetic, not only will turning up the audio system to full be highly likely to cause the signal to create clipping by the time it hits the speakers, but you can potentially damage your speakers.
Of course, someone like me, cobb2, MikeEnRegalia et al understand this and wouldn't go and crank an album with massive compression at full volume, but what about people that don't understand these sort of concepts?
It wont be any fun for them having to replace speakers because they turned up the volume to full with a stupidly over compressed album playing.

No, this won't distort- distortion occurs outside the +-3db range- the top and bottom of the graph. This is the job of the limiter- to remove any signals that go outside this range. They are just chopped off- removed entirely. Without the limiter this wave file would distort to hell. So, the compressor boosts the signal and the limiter removes anything outside the range of (most) playback units- louder music with no distortion. But as I said earlier this can only be done at this level with very expensive hardware gear, not software. The true meaning of DAW- a software workstation interacting with hardware effects. To get an idea think of the guitar and the effects pedal. The pedal is hardware and can do a much better job of controlling the signal that it is designed for, than say the software filters in a Pro Music Suite package. Even though they might be doing exactly the same thing, your guitar distortion (or whatever) is gonna sound better using a pedal, not a software effect filter.

Yeah, that's what I meant though.
The actual recording itself, isn't distorting. Death Magnetic may be very well be  distortion free (an unclipped signal).. I don't imagine they would be putting a distorted sounding album on the market.


An inherent feature of audio systems, is that the electronics themselves can produce distortion (a concept you may understand more than me, and something I'm sure some people on PA understand a lot more than me) and the speakers themselves, as I stated earlier.can be pushed into distortion. The more expensive high end units are obviously less prone to doing so, in terms of the electronics side of things, and generally louder wattage power amps deliver more headroom, allowing for more volume before distortion/clipping (with speakers to match of course).
I guess that can be a lesson 101, for those not in the knowTongue

What I really wanted to put across was that because of the extremely compressed audio of Death Magnetic, speakers and the audio systems themselves which are not free of distortion (unlike the album itself presumably) will be pushed into clipping more quickly because of the extra signal gain.
I mean, sure enough if I have my computer speakers at a reasonable volume they wont distort, whether I put on Opeth's Ghost Reveries (an example of a record with a very good dynamic range and as a given, not heavily compressed at all) or listen to Death Magnetic.... put them on full volume and they will, as a result of them just being small speakers with a low power amp.
Putting on Death Magnetic will only exacerbate the clipping problems at high volumes in my speakers.

Solid bar wave forms are apparently something joked about...... no one actually expected it would be for real, but I guess the production team behind Death Magnetic weren't aware of that joke and well...... did it for real.

^ I now have the cd ... so far it sounds good. Album Gain is at -13.20, which suggests heavy compression, but I've also seen a few albums which exceeded -14 ...

^ how much did it cost? At Amazon.de I only see the €69 special limited whatnot edition, which I am definitely not buying. I'm not going to spend more than €25 for the album.Approve

Representatives for Metallica acknowledged the mastering problem

"My name is Benjamin. I work in fan support for Mission: Metallica.

"I am sorry for the bulk e-mail, but we've heard from quite a few of you regarding the sound quality on the single release of 'The Day That Never Comes'.

"The source of the problem, as you might imagine, goes all the way back to the creation of the track from master — but this is not how it will sound on the album."


Metallica knew of the problem, had a representative state that it would be fixed, and still allowed it to ship with the problem. I would assume that the problem was identified too late in the manufacturing process of the disc and they let it go.

Here you can find a petition,asking  for album remastering, which is terribly clipping:

well, yesterday I listened to the album on my mobile player on the way back from work ... I noticed that the bass was distorted even at my normal volume setting (18/25). I'll listen on the computer today (Logitech speakers) and on my hi-fi.

Believe me, that's the same sh*t.If only I could hear it without annoying myself to the horrible sound.
For me, the bad quality really is f**king up my listening experience. Good music and decent recordings make me want to turn up the volume. I caught myself wanting to turn DOWN the volume on as well as my portable as my (quite nice, one might add) home set. Now, an album that makes me want to turn DOWN the volume can't be right.

Agree. Just spread this around :

 We got Metallica to release the Live Sh*t box set on DVD last year, so you never know.
