Imagine this scenario: you really love a  song on the CD you have just purchased. Surprisingly, you can’t stand listening  to it for very long and you’re not entirely sure why. Something urges you to  skip to another track. Again, you like the music but the feeling of a discomfort  is still there. Maybe you have just a bad day. More probably you are another  victim of the recording industry.

In the late 90's something went terribly wrong

RTH1As long ago as in  1982 red book CDs were released to the public. In the beginning it was a niche  market, therefore recording companies put a very little effort in the mastering  process and program material mostly remained untouched when being transferred  onto a silver disc - such CD’s were often tracked at very soft levels due to  engineers cutting straight from original analog mixes.

Only in the late 80’s,  with commercial CD players exploding onto the market, a mastering became a  legitimate profession. With more advanced digital equipment available in early  90’s mastering engineers could take a full advantage of CDs’ dynamic range  without a need to compress or clip. This was a golden age for CD recordings.


How is it possible that you cannot  enjoy your favorite music anymore? It is not your fault - it is the music with  no or very limited dynamic range that is physically difficult to listen to for  any length of time and urges you to skip the tracks. Quiet sounds and loud  sounds are squashed together, there is no contrast anymore. It is not natural  when four singers screaming their lungs out in a chorus are as loud as  whisperred verses of a song, when an unplugged guitar beats a kick drum in its  loudness. It’s also the reason why some people are still fanatical about vinyl  recordings of the good old days. It’s not necessarily that the vinyl sounds  better - it does not. It’s that it is impossible for a vinyl record to be  fatiguing.

David Bendeth, producer
“Over the past decade and a half, a revolution in  recording technology has changed the way albums are produced, mixed and mastered  - almost always for the worse”


The major shortcoming  of analog recording systems was always the noise floor of the medium, such as  tape hiss or surface noise (crackles and pops) on vinyl records. ALL analog  recording and playback media have some sort of inherent noise. To get as far  away as possible from this noise floor the loudness of the track was increased.  Thus program material was more clearly audible and farther above the noise and  the dynamic range of a recording increased.

But all analog media also  have their, technically speaking, ´saturation´ point: a limit over which the  sound would become distorted. This type of distortion gives a hot, fuzzy,  warmish sound. Can you remember how we were making tape recordings intentionally  hotter by overmodulation to get a better signal to noise ratio? Sometimes it was  used with care even by professionals to enhance immediacy of the material - e.g.  Rolling Stones were famous for this and nobody have ever objected.

Binary  digits have no inherited hiss or crackle (in fact, the CD playback requires the  introduction of a small amount of randomized noise - dither). Zero in dBFS (full  scale) is the the absolute highest level allowed for no clipping and distortion,  unlike analog VU scale, where zero is the average level and sound swings above  and below. The dBFS scale uses negative numbers to represent audio program level  below the maximum zero. Typically, -20dbFS = 0dB on VU (i.e. 0dB on VU leaves  approximately 20dB reserve for signal peaks on the dBFS scale).

There are  different ways of dB level referencing. To illustrate one of the approaches,  look at the following waveform - it is Dire Strait’s So Far Away from  their legendary Brothers in Arms (1985, Vertigo, 824499-2). The album was  mastered by Bob Ludwig and contributed tremendously, especially through its  convincing sonic qualities, to the rise of CD format when it was still young.  The paler waveform confined inside the spikes and peaks represents average  volume levels of the track and jagged peaks that move up and down on the scale  outline macrodynamics of the track. The bigger the distance between the peak  level and the average level, the more competent is a track (micro)dynamics-wise.




From today’s point of view, the  hereabove Dire Straits material was recorded in 1985 very quiet - there is a lot  of headroom (i.e. it could have been louder). There is an occassional transient  that comes closer to 0dBFS, but overall the peaks are hitting -5 to -8dBFS or  even lower, and there is a sufficient reserve for the dynamic range. The  original pressing of this CD features one of the biggest dynamic sweeps ever  seen in rock music: Brothers in Arms measure as much as -18dB in  microdynamics (the CD layer of the recent SACD remaster is, contrary to a  popular misconception, not that courageous as it stops around -8dB). The level  of -0.3dBFS formerly was considered as the loudest signal that was safe to put  on a CD, since some early CD processors would treat a 0dBFS sample as an error.  Thus the average level of audio is pretty low, but if you turn it up, these CDs  may sound excellent.

The trick is that listeners judge how loud a sound is based on its average loudness, not its peak loudness. So even  though there might be two tracks whose loudest parts (peaks) reach the same  loudness level in dBFS, the one with a higher average level will be  subjectivelly perceived as louder.

Dynamics is one of key elements  in any music, perhaps the most important - it is virtually light and shade of  the music. It creates a sense of spaciousness and makes it easier to pick out  individual sonic elements - room reverberation, resonance of the wooden body of  a guitar, the sound of strings being plucked, vocalist raising or lowering  her/his voice, a sudden rush of drums, a quiet section bursting into a  fortissimo passage - these elements bring an excitement to a music and when  those things are neutered, the excitement is lost.

Jerry Tub, Terra Nova Mastering
“Listening to something that’s mastered too hot  is like sitting in the front row at the movies - all the images are in your  face.”

Transients, the peaks  and valleys of a waveform, are necessary for the music to have a room to  breathe. When compressors are cranked to excessive levels these transients are  turned from sharp attacks to dull nubs and much of the detail is lost. The  result is the sound that is unnatural, distorted and painful to listen to. Even  if you like that type of sound initially you will not be able to enjoy it for  more than couple of minutes without feeling significant  discomfort.

Following two pictures show the same track: Garbage’s famous Milk. The first outtake is from the original CD (1995), the second sample  comes from Absolute Garbage compilation released in 2007. Mastered by Emily Lazar and Sarah Register at The Lodge the latter version, though not  clipped, is compressed and not nice to human ears at  all.





Geoff  Emerick, engineer on the Beatles’ Sgt. Pepper album
“A lot of what is  released today is basically a scrunched-up mess. Whole layers of sound are  missing. It is because record companies do not trust listener to decide  themselves if they want to turn up the volume.”


There are number of ways to reduce the  difference between the loudest and quietest parts of a musical track to either  bring some instruments forward in a mix or make the track louder. Most of the  methods, if applied insensitively, often result into reducing the original  dynamic range of a recording.

One of the safest types is the normalization of a recording: the normalization process searches for a peak which is then turned up to 0dbFS together with the rest of the recording.  The process does not change the ratios between peaks and the average loudness of the  track. Thus you would get the hottest possible CD output without a distortion or  change in dynamics.

mari-boineSometimes just one transient (or a limited number of  them) peaks over a signal’s average levels and therefore you won’t be able to  squeeze much extra volume out of the signal. Here’s where a limiting comes into a play: if we just tame a small number (i.e. occassional) peaks, than  we can get the entire signal hotter. Used properly this approach results in an  imperceptible change to a small number of peaks and the whole signal can be made  louder, sometimes considerably so. This approach also achieves maximum volume  while still preserving 99% of the original material. The limiting is applied  throughout e.g. Paul Simon’s Surprise album (1996, Warner). Mari Boine’ s  Katrin Who Smiles (Goaskinviellja, 521 388-2 Verve, 1993) is  another example: the picture shows the enormous dynamic range of the track which  easily exceeds 15dBFS, however, if you look at the peak at around 4’48 minute  mark, you will see that its waveform is clipped (´flat topped´).



The  isolated clipping is a very rare phenomenon throughout the album enabling music  to sound louder by 3dB or more by sacrificing only a few isolated peaks - I  would say it is perfectly okay. Similar approach was applied when John Atkinson  mastered Attention Screen’s Live At Merkin Hall (STPH018-2) album for  Stereophile label: it was possible to keep all samples unclipped but it  was not necessary. Still, the dynamics of the album range between 10 to 15dBFS which is fine for a jazz recording.

Peter  Mew, engineer on David Bowie’s classic albums
“The quieter parts are  becoming louder and the loudest parts are just becoming a buzz. The brain is not  geared to accept buzzing. The Cd’s become psychollogically tiring and almost  impossible to listen to.”

One of the most misused  methods to make the music more ear-grabbing is a compression - the  loudest parts are made quieter (that is compressed through a compressor) and  this allows turn the whole thing up. It does not distort music and does not clip  but it will affect dynamic ratios of a music track. A more extreme kind of the  compression is a compression at a very high ratio. Sonically it brings some (or  all) instruments more forward in a mix and as a result it affects soundstaging.  It is normally used by radios to make the output loudness level uniform. Every  commercial radio uses some kind of audio processing in order to deliver a  consistent volume level. If they do not do that we would have to adjust volume  for each song - so the goal here is to make every song at a fairly equal volume.  This is done by compressing, limiting and sometimes clipping the audio material,  often together with some additional equalization. That’s also why a track on a  radio would be mistakenly considered to be of ‘a higher quality’ than the same  track played back through your consumer-grade home audio kit.

To  visualize the difference between the beauty of being natural and the fuziness of a distorted reality please inspect the following images:

The first one is  Leonardo da Vinci's reprint of famous Mona Lisa. The second picture is a compressed (low resolution) version of the same and finally, the third picture  is ´clipped´, i.e. distorted a bit. No need to explain more. Now, you have an idea what a crap do we listen to?




Digital brickwall limiting is a more recent computer aided limiting in a digital  domain by software plug-ins. If used sensitively it is very powerful as one can review his or her work before it is “published” - it does not necessarily cause flat-topping, but still removes the transient punch and impact from the  sound.

Bob  Dylan, musician in interview for Rolling Stone magazine
“You listen to  these modern records, they are atrocious, they have sound all over them. There’s  no definition of nothing, no vocal, no nothing, just like -  static”

When you cannot compress or limit more, the only way to make your music even hotter is to simply chop off the peaks. Such a clipping results in perfectly flat lines of different lengths (which never occur in any naturally recorded music) and is the most ear fatigue inducing method  to get the things loud.

CD digital audio runs at 44,1kHz (that is 44,100  samples per second). If, let’s say in a song, 10 samples are over the top, it’s  10/44100th of a second - far too quick to be heard. It means that not all clippings (the peaks that are over 0dBFS) are audible - the human hearing is very tolerant and forgiving. For example, Sony have introduced a three sample standard for measuring the level of distortion (i.e. 3 subsequent samples are over the limit) for the recording industry.

As a cheat sometimes a soft clipping method is used - the peaks over 0dBFS are lopped off but not flattened - instead the flat top is recreated again in a faked simulation of a rounded curve that looks like a natural part of the waveform). The soft  clipping cannot be revealed by an inspection but if it is overdone it results in the same type of distortion as the standard clipping.

Roger  Nichols, Grammy winning engineer for Steely Dan, Beach Boys and more (courtesy  of Eq magazine, January 2002)
“I listened to all the CDs submitted to  NARAS for cosnideration in the “Best Engineered Non-Classical” Grammy category.  Every single CD was squashed to death with no dynamic range…the finalizers and  plug-ins were cranked to eleven so that their CD would be the loudest. Not one  attempted to take advantage of the dynamic range or cleanliness of digital  recording.”

As an example let’s take my favorite German experimental thrashers from 80´s, Mekong Delta. The Transgressor track from their best to date Dances of Death album  (1990, Aaarrg ARG23/034-2, mastered by Ralph Hubert) reads very low average  loudness and its dynamic range peaks have an ample headroom of 14dB (!) - the CD  is really very quiet and a volume control has to be turned up significantly to  make it rock. However, it boasts one of the finest available dynamic ranges  (16dB) and dynamic-wise it beats easily releases like The Dark Side of The  Moon of Pink Floyd.

Unfortunately, this unique achievement was readily ‘fixed’ with the same track that appeared on the superb (viewed from the point of its track list) Mekong Delta’s compilation album in 2005 (Membran 223132-311). Can you spot the difference on the second picture? Despite the mutilation that was performed to the track it is not clipped at least, better say it is only soft clipped. You see that the dynamics of the track  hardly exceed 5-6dBFS and there are no quiter moments - the track peaks all the way long. No need to say that sonically the difference between both CDs is a heaven and hell (the hell stands for the more recent version). Ironically enough, the booklet of this CD boasts with the sentence: 24bit/96kHz High-End Mastering! Even if I do not consider all those editing clicks (loud popping sounds) that are audible throughout the album I have to ask: With all my  admiration towards your music, are you sane, Mr.  Hubert?




RTH-sample MekongDelta


Probably  not - let’s have a look at the very latest output of the band: Moderato has been taken out from Lurking Fear (2007, AFM Records, mastered by  Ralph Hubert again). Such a CD could be listened to only in car and even there it sounds awfully.




In case of a digital recording, when peaks are clipped, they are lost forever. There is no way how to restore the information back - it means that the music is destroyed forever. A powerful blast of a kick drum should be quite loud and should have a sharp transient on the front of its waveform. In case of severe clipping,  the wave produces just a quick blast of distortion and a dull thudding sensation (though it may be appealing to some non-audiophiles).

If you listen to an  80’s rock CD at a moderate volume, the drums are usually on the same level or a bit louder than vocals. But in today’s recordings it is all about SHOUTING - no drums, no beat or rhythm; during chorus, when a drum kit should be the loudest,  it may be barely audible in a wall of sound, being turned into a clicking sound in a background noise!

Famous Californication of Red Hot Chilli  Peppers and Elect The Dead of Serj Tankian (solo effort of the frontman of System of A Down) are both prime examples of the brutally distorted and squashed-to-death music.




RTH-rhcp californicationWith Right On Time (RHCP, Californication, Warner 9362473862), produced by Rick Rubin, you can easily see the example (above) of such a wall of sound with  practically no room for dynamics left. It is even impossible to speak about flattened peaks - there are simply no peaks anymore; almost everything is  flattened at the maximum 0dBFS level. If you added up the number of missing digital data samples, you would find out that in certain moments over 55% of the song’s sonic information is missing!


RTH-tankianNow, look at Tankian’s Empty Walls which is a favorite cut for many rock radios. Not only is it  treated as badly as Californication but on top of that, the overall CD  level is brought by 5dBFS down, preserving all the nasties at the lower volume.  Was it a purpose or an accident? Does not really matter as the music strongly  resembles the sound of your mobile phone no matter how good is your hi-fi gear.


RTH-sample Tankian


Good mastering is always a compromise. By equalization individual proportions of music could be changed, yet by an insensitive  compression the whole original music idea could be destroyed. Ideally, mastering  engineers should just transfer a tape onto a digital medium without leaving any imprint on its original sound. I still prefer some tape hiss to the  hiss removed together with some music. So why there is a pressure on mastering  studios to manipulate originals to the extent they are becoming harmful to our  hearing?

Today, we listen to music in much noisier environments and use it rather as background. It is virtually everywhere - at work, in pubs, in cars,  in shops, at airports. Moreover we want to listen to the music we love via iPods  with headphones even in the noisiest of environments, in a constant hum from  traffic in streets for instance. Have you ever tried to listen to a well  recorded classical music piece in your car? You will probably find yourself to  turn the volume of your car audio up and up in order to hear quiet parts and  finally you will have to give up as you’ll be not able to hear a damn  thing.

If an audio dealer wants to grab your attention and to highlight a certain component it is sufficient when he cranks up the volume a bit. The same technique is deployed by TV stations to grab your attention by commercials -  have you ever noticed they are louder than the rest of a programme? The same effect used to be utilized already in the vinyl era with 45 singles -  Motown label was notorious for cutting some of the hottest singles in industry, for example. They just made you dance. However, if you make music louder by +2 or +3 dB the next year you will have to add another 2dB to sound competitive. What was considered over the top one year, became standard the next. In the early to late 80’s, most pop records averaged around -15dBFS. Yet five years ago, CDs averaged at around -10 to -8 dBFS. Nowadays, modern recordings with a -2dB of dynamic range and no headroom are not an exception.  In fact, this has become a rule!

When the red-book CD format was introduced, one of its promises was its potential for 96dB of a dynamic range. Higher resolution formats enhanced this potential to 144dB (DVD-A) or 120dB  (SACD). From the softest sound up to a threshold of pain, human hearing can  encompass a theoretical range of about 130dB. This is far above what we can use  for our musical enjoyment at homes - despite the progress the new recording and playback technologies have made we are forced to buy and listen to recordings with their dynamic range not exceeding 2 to 5dB. Yes, it is that bad.

Bob Katz, recognized producer and sound engineer that is signed  below more than 150 albums for the audiophile Chesky Records label and runs  Digital Domain mastering studios, says: “Recently I have been addressed by a well known jazz pianist, with a trio of some of the finest jazz musicians on the  planet, saying that he loved his master, but he’s willing to sacrifice its sound  to make it a little more competitive loudness-wise. Why would he have to be the least bit concerned about a jazz recording being “competitively loud?” Today, with ongoing commercialization of jazz and classical music (with the help of movies and their scores) there are signs that the loudness war extends also to these territories, especially with the most popular releases. Fortunately,  the classic labels are a bit more careful (or hesitant) as an insensitive and excessive digital treatment may easily ruin their reputation. When we  move to rock and pop music we find ourselves amidst of a devastated battlefield.

Bob  Katz, Digital Domain (sound engineer and ex-technical director of  Chesky)
"There’s a 12-14dB apparent loudness difference between Black Sabbath produced in 1977 and transferred to compact disc in the early 80’s, and the Black Eyed Peas‘ Let’s Get It Started"


RTH-blacksabbathWith rock legends it is quite risky for an engineer to make a  messy mastering job. Here mastering engineers are much more careful and clipping  occurs rarely though equalization and compression to a certain extent is widely  applied to make the recorded material louder, as seen on one of the re-issues of  Black Sabbath’s backcatalogue:



RTH-sample BlackSabbathOriginal


The  above wave is out of The Wizard from their self-titled debut as it appeared on the Castle (RAWDD145) compilation album in 2000. You see that the crest wave still has enough headroom with its ca -5dBFS peaks. The average  loudness of the re-release from 2004 (Sanctuary SMRCD031, remastered by Ray  Staff of Whitfield Street Studios from original tapes) was increased by some  +3dB which is still pretty safe for the peaks (below).



RTH-sample BlackSabbathRemaster

At the same time, a kind of noise  reduction may have been applied which resulted in a slight alteration of  transients (that are now visibly sharper) and it also facilitated clearer, less  organic and more punchy sound (e.g.cymbals are perhaps too ‘metallic’) and  audible changes in a soundstage focus, yet preserving most of its original  dynamic scale.

Thus, the remastering job conducted on Black Sabbath’s debut as well as on the subsequent Paranoid album (Sanctuary SMRCD032,  the same remastering credits and nice microdynamics of 11dB) is quite well done  and with some minor criticism fully acceptable even in ´audiophile´terms.


RTH-acdcAlso remasters of AC/DC’s High Voltage (7567-92413-2,  Atlantic, remastered by Ted Jensen of Sterling Sound from original tapes, 1994)  and Rainbow’s Rising (823 655-2, Polygram, remastered by Dennis M. Drake)  could have been good achievements if the more drastic methods had not been  applied. On She’s Got Balls from AC/DC’s debut not only you can see Mr.  Jensen tried to maximize the overall loudness, but he also sacrificed a good  deal of transients in favor of clipping - on the picture below the flattened  wave parts containing as much as 7 samples in line are  recognizable:



RTH-sample ACDC

Fuelling further distortion into already  ‘distorted’ guitar rock riffing is not a disaster and it is forgivable -  the music is more crispy, punchy and really rocks; anyway, when you compare it to an original vinyl pressing you would hear that the remastered  version is a bit over the top.

Here and there you can hear voices calling  for a jihad against some mastering engineers for their inconsistent work but in  my opinion it oversimplifies the problem. For sure, the mastering engineers should not be the ones to promote aforementioned sound mutilations - this should  be considered a professional suicide. However, there is an existing pressure  from their customer, that is a label or often from even an artist, that forces  them go over the top.


RTH-NirvanaLet’s take, for instance, famous Masterdisk studios and  Howie Weinberg - this guy is behind some legendary releases like Nirvana’s Nevermind (1991, Geffen 424425-2). Despite Nevermind is not considered to be a real audiophile treat, it was pretty innovative and you cannot deny it set new standards for loudness levels and new ways of mastering.  By the way, despite occassional and forgivable clipping Smells Like A Teen  Spirit enjoys remarkable 12dB of its dynamic range which is a top notch achievement for an indie record (below).



RTH-sample Nirvana


Unfortunately, Howie  Weinberg’s more recent mastering projects are far from being acceptable - the list of popular artists whose recordings have been squashed beyond recognition is long, with prime example of frequently discussed and totally unlistenable  Rush’s Vapor Trails that should be nominated as one of the worst  achievements of mastering to date. There are petitions on the internet calling  for Vapor Trails to be properly re-mastered and even more voices are calling for a re-issue of Metallica’s recent Death Magnetic CD (mastered  by Ted Jensen) which shows signs of terrible compression in comparison with its PlayStation (!) version. It is a miracle (or rather a pitiful fact) that such a release was awarded by Grammy for its sound quality.


Not necessarily. However, it is  more and more difficult to find a music material which has benefited from its  enhanced quality due to a proper remastering process. One of the examples could  be the new Dead Can Dance set that is available in a hybrid SACD/CD  format.


RTH-dead-can-spiritchaserSome of the original material, released on CDs in 90’s, was  already of a pretty nice sound quality and the high-resolution of the SACD  justified perfectly the re-release. Fortunately, as albums come as hybrid discs,  we can also enjoy the enhancement in the standard of 16bit/44.1kHz. Let’s take a look at the samples picked out from great Spirit Chaser CD (4AD, CAD  6008, 1997, no mastering credits) - the track number 4, The Song of  Dispossessed. Peaks go up to 0dbFS level but because the track’s average  loudness is pretty low, the peaks generate a remarkable dynamic range. I do not know if the CD was either normalized or carefully mastered but you can hardly reveal signs of any insensitive compression - if one really tries hard than there is a peak or two that had been cut off (see the picture below), however, the effect of this is inaudible as it goes beyond the human hearing  sensitivity.


RTH-sample DCDOriginal


RTH-deadcandanceDuring the  remastering process (Dead Can Dance, Spirit Chaser, MFSL remastered  Hybrid SACD/CD SAD2713, 2008), Neal Harris of Mobile Fidelity Sound Lab treated  those small imperfections (on the picture you can see that the lopped-off peaks  are back) to enhance the sound quality the MFSL way:


RTH-sample DCDRemaster

Though these  ‘improvements’ are not significant on their own (the difference between the  original flattened peak and the new reconstructed peak is below 0.4dBFS), their  cumulative effect has an impact on the sound. The MFSL version is  compressed to a very little extent, so its overall RMS (average loudness) is a bit higher, but this was necessary to get all the details and transients right. The resulting sound acquired a higher level of clarity and brilliance, indeed.

Another example of a success story of modern remastering is Mike Oldfield’s Tubular Bells (25th Anniversary Edition, Virgin  CDVX2001, remastered by Simon Heyworth) or famous Rolling Stones backcatalogue. The latter was transferred to SACD/CD hybrids for ABKCO label by joint efforts of Teri Landi, Steve Rosenthal, Jon Astley and Bob Ludwig.

In an interview for Pro Audio Review magazine Bob Ludwig described how painstaking the whole process had been:
“I would put up a song and EQ it the way I thought it should be.  Then I checked it against original London and Decca pressings and also checked the singles if the original was mono. Next, the 1986 CDs would be checked as this was source for probably 90% of the people who know these  songs.”


RTH-rolling stones-studio


RTH-rollingstones remasteredTo  get the most out of the medium, also Rolling Stones transfers have been compressed, using analog compressors (Manley, Millenia Media or NTP) to get the  ‘correct’ sound. Ludwig  Co. went step by step through all tracks to erase or minimize all nasties inherited from the master tapes: “When there were spots that required the use of noise reduction I would do it, if it was possible  in the analog world. If not, we went to the high-resolution PCM format. If  neither sounded that great, we just let the noise be.”  Though the issue was targeted to an SACD audience, its CD layer benefits significantly from the Sony’s Super Bit Map Direct SACD to PCM downsampling and the final remaster has become one of the milestones in the industry.


It’s clear that the as-loud-as-possible epidemics will not stop in  near future. There are no signs of recovery:  the latest Rammstein’s opus  Liebe ist fur Alle Da (2009, Universal 2721359, mastered by Erik Broheden  and Henrik Jonsson at Masters of Audio, Stockholm) is, due to a rough digital processing, sonically not far from the sound of your Nokia cell phone. A prime  example of how a piece of music can be killed by an incompetent treatment.



Before this article  was published I had come across another 'sonic gem' - the latest output of  Combichrist (What's The F***k is Wrong with You CD). The title of the CD  is an excellent choice; if you look at the waveform (below) you really have to ask the very same question...



Not  to be confined only to a rock territory, Michael Jackson’s post-mortem This is It (Sony/Epic  88697606742) is another example of such an incompetence: where original releases showed nice dynamics of up to 13dBFS,  there left hardly half of it on This is It.

By now, any audio enthusiast should have already realized that excellent dynamic capabilities of a recording do not mean that its sonics are excellent too. There are many examples of recordings that, despite their decent dynamic range, failed at some other stage in their mix and left a demanding listener dissapointed with the lack of an ultimate resolution, soundstaging precision or perhaps just an emotional communication. On the  other hand, even if the aforementioned audiophile requirements are met, without appropriate dynamics the music turns out to be a crap.

An  audio forum member:
“When CDs came about I got rid of all my cassettes and  vinyl records and replaced them with the CD versions. When MP3 came around I  downloaded my face off. Now I feel like an idot.”

During the preparation of this article throughout 2009 I analyzed more  than 300 rock and pop albums for their dynamic range and the level of their  compression. I would like to bring better news but I am very sorry: the more recent a title is the more it is affected. Unless we talk about carefully  supervised anniversary editions you can hardly expect a well executed mastering  job today. On the contrary - when you spot a ´remastered´label on the jewel box  of a CD you have to become very suspicious about its quality. The green line on  the picture below shows average dynamics of CDs fifteen years ago, the red line shows the situation of today. The CDs that used to have 14dB dynamics in the  late 80´s hardly hit at least 5dB level when remastered. Today, the ´REMASTERED´label can be easily replaced by a ´STAY AWAY!´label in 90% of the cases.




Turn Me UP

We  may only hope that the plague will not spread furthermore. There is a  significant advantage - a cheap and quick remedy is available. Since 2008,  Audiodrom has been therefore a proud member of TurnMeUp! initiative ( which has already grown up to quite  a strong movement that is gaining its momentum.

Started by the  sound engineer Charles Dye, supported by such authorities like Bob Katz or Bob  Ludwig and many more, TurnMeUp! leads the campaign to restore to artists the  choice to release more dynamic-sounding records. The Turn Me Up! website  ( includes a great tutorial video on the loudness issue, as  well as a growing list of links to articles on the subject.


We are  also keen supporters of another initiative The Pleasurize Music Foundation ( which began operations in  January 2009 and is a nonprofit organization based in California, USA. This  organization has quite an ambitious goal to convince record companies to release albums with the minimum dynamic range of 14dB or, alternatively, to give less  dynamic albums appropriate headroom and label them with a logo showing their  actual dynamic range. We encourage you to learn more on their web where you can also find a software tool for the dynamic range measurement.

By  widespreading the message (Stereophile magazine is one of those relentlessly  rebelling) and developing enough pressure on artists themselves (remember the  latest outputs of Depeche Mode or Metallica that dissapointed many) there surely  will be a day again, when we would be buying music without the fear that it will  damage our souls and ears.

As Graham Sutton, musician and sound  engineer says:
“The brick wall has been reached. I wonder how long it will  be before the record companies re-re-release their back catalogue,  re-re-remastered for additional dynamic range.”
