That is fine when a song goes from low to high, I love that! Great dynamic range like it should be. It's when the whole song is nothing but loud, that is what I don't like. ie: Death Magnetic
you are supposed to be listening to the highs and lows BEFORE the 36 second outburst.
those rise and falls before that loud part are what audiophiles call dynamics.
the loud outburst at 36 seconds is simply an increase in volume.. and while it is preferable in an orchestra pit, because it makes the whole pit glow with audio, it isnt the same beautiful thing when you stick a microphone in there to record it.
and it isnt ANYTHING close when movies do it with their stupid explosions.
i'm not being mean or cruel in sway with the economy..
i'm trying to tell you the difference.
those orchestra pits are usually the dome where it looks like you take a ball and cut it in half.. and then cut that piece in half to seperate the top from the bottom.
and when you are in the audience, those large outbursts can be translated to how lights perform.
the translation goes as follows..
you get a curtain and hang it up vertically, and you've got dozens of lights that are moving around the curtain like a lazer pointer.
then you get this one light that comes along and lights up the whole curtain.
can also be translated to fireworks..
you've got all these smaller explosions, and then one big one that is wider than all of them.
dynamics are about the different sizes of the smaller fireworks.. the different sizes of the smaller lights.. the different sizes of the very subtle rises and falls in the audio.
not the large ones that make you jump.
it makes sense to think about it if you realize exactly why the word dynamics (for audio) is used in the first place.
that reason is the amplifier.
because an amplifier is designed in one of two ways:
1. there is a straight line of volume that is capable of large amounts of volume increase (and this brings on the volume knob)
2. there is a straight line of volume that is NOT capable of large amounts of volume increase.. but the straight line can go up and down 5dB without any problems (and this brings no volume knob.. much like a preamp)
for a long time..
there was either one or the other.
and trust me.. if you've got a straight line of 70dB that refuses to do 71dB or 72dB or 73dB (or any other decibel) ... then what you said about the emotion being sucked out of the audio is exactly true.
way back in the roman days..
if they were playing music for the whole family.. they had to swap out different battery packs for specific parts of the music.
because those battery packs were ment for a small change in volume.. or loud changes in volume.
all of the audio before 36 seconds would need to be on one battery pack.. and then the battery pack would need to be switched for the loud outburst at 36 seconds.
and if there wasnt any time to switch back to the soft volume.. anything soft would suffer, or get stretched out to something really loud.
a lot of the amplifiers from the 1950's and earlier will show you the clamp i was talking about.
there is always the 1-5dB difference
and then some large scream that takes up all of the amplifiers power for a brief moment.
the important thing to note here is..
there are headphones being sold that dont do a good job of showing those soft changes for the audio from the start of the video up to 36 seconds.
all of that audio has lots of small rises and falls.
that is partially the reason i bring up 'cardboard sound' when describing a speaker.
it is because the speaker is too dull and unresponsive to output those small changes in volume.
the beauty of what i know is..
if you seek the path of those small changes in volume.. things start to get blistering fast, and when that happens.. you can actually begin to hear audio lay itself on top (or behind) a different piece of audio.
for example..
if you are watching a movie and there is a female actor and a male actor with a deep voice.. both of those people can be talking at the same time and it sounds like there is air (or empty space) between those two voices.
that has been high-end for speakers since the inception back in the 1960's
and it became that way thanks to the many radio broadcasts BEFORE that time, back when radio companies were putting in very high quality speakers and amplifiers into the radio to see who would sit down and warm up the voice coil long enough to hear the improvement.
matter of fact,
consumers seen the depth stretch larger and larger and larger.
if you keep stretching it.. you'll find two seperate layers of audio.
and if you think two is impressive.. try five layers or more.
many people are struggling to see the stretch of one single layer.. that is why i say audio has become an embarrasment.
one cardboard sound after another, and instead of getting the full frequency response.. they switch to 2-way speakers with a subwoofer.
i mean c'mon..
the frequency response is stated as 20hz - 20khz
but people let their system stop as high as 60hz ... and the worldwide average is 40hz
simply hearing a subwoofer that plays down to 30hz is an improvement to people.
and then it happens again when the sub plays down to 20hz
people call it extra money because the speaker box is bigger.
you dont cook like that do you?
when it says 1/3 cup of water.. you dont totally go without any water.
i guess the confusion comes from cooking.
because people are always trying to lower the oven temperature.. or remove a few minutes from the cooking time.. or add less water.. or instead of using water, use milk.
all of that to get your PRE-SET recipe tasting better.
it is chemistry.. and you didnt add any powder chemicals, but you might of made the powder that comes with it a bit poisenous for excessive long-term use.
people dont learn because they dont know why they get old and die.
if they get organ damage.. and the organ damage doesnt kill them.. then they never know what they did was wrong.
we've got to look at the governments instructions and take them literally in a time when they are requesting it the most.
no sense doing all that team work, and then you come along saying the team didnt try hard enough.
we wouldnt be talking on this internet forum without team work.
there are always people that think something special is hidden deep inside of whatever they touch.
most of the time there isnt.
and that team work has done their job to make sure you cant make it into anything special.. because if you can make it special, you should be building your own and selling your products that might actually prove to be heavy-duty compared to the stuff on the shelves.
(but i think this chance has officially came and went.. because society is wising up to the lack of heavy-duty.. or simply growing 'used' to the low duty)
long post w/ multiple points
let them know you care!
