بوی باران

boyebaran

بوی باران ، بوی سبزه ، بوی خاک

شاخه‌های شسته ، باران خورده ، پاک

آسمان آبی و ابر سپید

برگ‌های سبز بید

عطر نرگس ، رقص باد

نغمه‌ی شوق پرستوهای شاد

خلوت گرم کبوترهای مست

نرم نرمک می‌رسد اینک بهار

خوش بحال روزگار

خوش بحال چشمه‌ها و دشت‌ها

خوش بحال دانه‌ها و سبزه‌ها

خوش بحال غنچه‌های نیمه‌باز

خوش بحال دختر میخک که میخندد به ناز

خوش بحال جام لبریز از شراب

خوش بحال آفتاب

ای دل من گرچه در این روزگار

جامه‌ی رنگین نمی‌پوشی بکام

باده‌ی رنگین نمی‌بینی به جام

نقل وسبزه در میان سفره نیست

جامت از آن می که می‌باید تهی است؛

ای دریغ از تو اگر چون گل نرقصی با نسیم

ای دریغ از من اگر مستم نسازد آفتاب

ای دریغ از ما اگر کامی نگیریم از بهار

گر نکوبی شیشه غم را به سنگ

هفت رنگش می‌شود هفتاد رنگ…

چیزی که دلم میخواست در موردش قبل از تحویل سال بنویسم اتفاقاتی بود که بعد از انتخابات افتاد و ما عزیزان زیادی رو بخاطر یک اعتراض از دست دادیم ، من میدونم خانواده های این عزیزان الان که نزدیک به تحویل سال هست چقدر دلتنگ فرزندانشون هستند. ای کاش آزادی بهایی چنین سنگین نداشت

شاخص های صدا:

از آنجایی که شاخص های صدا همان اجزای صدا هستند و مغز ما بجای مد شنیدن کل وارد مد تمرکز بر روی اجزای صدا میشود من مناسب دیدم قبل از اینکه از درک کل به سمت n شاخص برویم بهتر است یک دسته بندی داشته باشیم تا کم کم وارد جزئیات بیشتر شویم و برخلاف روش رایج (http://stereophile.com/reference/50/) یک دفعه با کلی مفاهیم روبرو نشویم. من یک مرز بندی دقیق ارائه نمیکنم و معتقدم کلا امکان این کار هم در عمل وجود نداره و سعی میکنم بر اساس درک مغزم از صدا یک دسته بندی داشته باشم و همه پارامترها را در این چهار چوب توضیح بدم.

دسته بندی من به شکل زیر هست:

  • Presence of Sound in Space (Static)
  • Harmonic Structure (Static)
  • Dynamic Structure (Dynamic)
  • Transparency & Neutrality (Vertical Parameter)

این دسته بندی بر اساس نوع تاثیر سیستم ها بر صدا و نوع درک مغز من از این تاثیرات هست و البته سعی میکنم نوشته های رابرت هارلی، مایک، رومی، کالمز، جان گوردن و آرتور رو هم مورد توجه قرار بدم و در مورد معنی مفاهیم ای که در نوشته های آنها هم استفاده میشه به این دایره اضافه کنم و در موردشون توضیح بدم.

بخش اول مربوط به مشخصات تصویر صدا Imaging , Soundstage و کلا شکل موجودیت صدا در اتاق میشود.

مثلا در یک اجرای زنده Live هر سازی از یک مکان خاص شنیده میشود و مشخصات مکانی ساز و مشخصه تصویر آن (ابعاد چشمه صوتی) یک چیز مشخص و قابل درک برای مغز میباشد.

وقتی تار را از فاصله ای خاص میشنویم مغز براحتی مکان سورس صدا را تشخیص داده و اندازه سورس صدا نیز قابل درک است ، مثلا احساس نمیکنید اندازه دهان خواننده بزرگتر از حد معمول است و یا اطلاعات مربوط به Ambience فضای اجرا در این دسته قابل طبقه بندی است.

کلا شکل حضور صدا در اتاق رو من در یک گروه قرار دادم بنام Presence of Sound in Space .

دسته دوم مربوط به اون اطلاعات ای میشه که در ساختار هارمونیکی صدای یک ساز هست و با شاخص هایی چون Timbre ، Texture و Low Level information هایی سروکار داریم که کلا به وضعیت هارمونیکی یک صدا مربوط میشوند.

دسته سوم به خصوصیات داینامیکی صدا توجه داره که بیشتر به میزان انتقال صحیح انرژی در طول زمان وابسته هست. در این بخش ساختار دینامیکی صدا بررسی میشود و حس حرکتی در استرینگ های صدا مورد توجه قرار میگیرد.

دسته چهارم به میزان ره یافت شنونده به صدا ربط داره ، یعنی چقدر فلان شاخص مورد نظر صدا خالص ، و شفاف و تمیز هست و من عبارت Transparency و Neutrality رو بعنوان یک عبارت کلی برای این نوع از شاخص ها انتخاب کردم که عبارت Transparency برای میزان ره یافت ما به اون شاخص صدا اشاره داره و Neutrality به نزدیکی اون شاخص به حد تعادل یا همان خط بالانس.

در سه بخش اول ما با سه دسته شاخص ها در صدا روبروییم اما در بخش چهارم ما به ره یافت شنونده در سه شاخص قبلی توجه میکنیم که حالتی Vertical داره تا یک دسته موازی با بقیه دسته ها.

البته این توضیحاتی که دادم خیلی اولیه و شاید گنگ باشه، اجازه بدید بطور مفصل همه این دسته بندی ها رو توضیح میدم و سعی میکنم با مثال هایی موضوع رو روشن تر کنم اما برای شروع همین حالا سیستم رو روشن کنید و به این چهار بخش دقت کنید، شکل حضور صدا در اتاق، جنس صدای ساز ، حس حرکتی موسیقی و شفافیت ای که حس میکنید در صدا.

تکرار میکنم این طبقه بندی مختص درک مغز من هست و مثلا با طبقه بندی مایک یا طبقه بندی گروه EBU فرق میکنه (البته من و مایک نزدیکتریم) اما در نهایت من سعی میکنم همه اونها رو تو همین چهار گروه خودم توضیح بدم. بد نیست الان نوشته های آقایان Hoeg  وChristensen و Walker رو بخونید که مربوط به گروه EBU هست.

این گروه به شکل زیر طبقه بندی کرده :

Spatial impression :

– Homogeneity of spatial sound

– Reverberance

– Acoustical balance

– Apparent room size

– Depth perspective

– Sound colour of reverberation

Stereo impression :

– Directional balance

– Stability

– Sound image width

– Location accuracy

Transparency :

– Sound source definition

– Time definition

– Intelligibility

Sound balance :

– Loudness balance

– Dynamic range

Timbre :

– Sound colour

– Sound attack

Freedom from noise and distortions

Main impression

چیزی که جالبه اینه که من تو سال ۱۳۸۳ در دفترم یک طبقه بندی دیگه داشتم که براتون اینجا میارمش و کم کم این دسته بندی تغییر کرد تا به شکلی که در بالا آوردم دراومد و جالبه خیلی هم شبیه به دسته بندی مایک شد، از مایک بپرسم اون ۵ سال پیش تو دفترش چیزی نوشته بود یا نه :)

دسته بندی ۵ سال پیش من به شرح زیر بود :

Music Flow

Definition Across Soundstage

Control and Timing

Dynamic and Attack

Bandwidth and Background noise

Distortion

Long listening State (effect of sound on brain)

یک دسته بندی دیگه هم تو سایت TNT Audio دیدم که کمی ابتدایی بنظر میرسه :

The PRaT & emotion group

  • Rhythm
  • Timing
  • Pace
  • Tingle factor

The low-end

  • bass depth/extension
  • bass pitch/tunefulness
  • bass speed
  • bass clarity or tightness

The midrange & vocals

  • Vocal/instrument pitch/tunefulness
  • Vocal/instrument intelligibility/clarity
  • Vocal/instrument realism/timbre/naturalness
  • Vocal/instrument embodiment

The top-end

  • Treble pitch/tunefulness
  • Treble clarity
  • Treble timing/integration
  • Treble sweetness

Hifi attributes

  • Soundstage realism/stability
  • Soundstage width
  • Soundstage depth
  • Soundstage height illusion

The other essentials

  • Fuzziness (negative parameter suggested by my partner Heather during the anti-vibration shootout, described as “diffusion” by some)
  • Virtuality? (accurate instrumental timbre realism, contrasts, not that pinpoint imagery delusion)
  • micro-dynamics (subtle nuances & contrasts too)
  • macro-dynamics

میرسیم به تحلیل صدا:

اولا دقت کنید که نمیشه صدای بازسازی شده رو کاملا با صدای زنده مقایسه کرد چون مثلا همین استریو بودن محدودیت هایی مثل Crosstalk داره که نمیشه با اون بدون پردازش دیجیتال به یک تصویر درست رسید و یا تو استودیو ها اونقدر تغییرات روی یک رکورد اعمال میکنند که خیلی چیزها این وسط جابجا میشه و از حالت اولیه دور میشه. در این مورد بعدا بیشتر مینویسم اما منظور من اینه کلا تو تحلیل صدا ما یک رفرنس مطلق بنام اجرای زنده نداریم و بیشتر در فضای نسبی صدای کامپوننت ها قرار داریم.

شنیدن اجرای زنده هم در کنار شنیدن صدای کامپوننت های مختلف به ما کمک خواهد کرد تا دید بهتری داشته باشیم اما در حالت کلی یک تحلیل بیشتر بر مبنای تفاوت صدای کامپوننت ها نوشته میشه. شاید بگید خب اینکه کمی نگران کننده است از اینکه این فضا میشه یک فضای نسبی و نداشتن رفرنس درست ممکنه ما رو به اشتباه بندازه که البته نگرانی شما تا حدی در مورد تحلیل گرانی که تجربه بالایی ندارند صادقه (مثل اشتباه احمقانه ای که صنعت صدا سر جایگزینی آنالوگ با دیجیتال کرد) اما در حالت کلی من معتقدم در همین فضای نسبی میشه به درک درستی از صدا رسید.

رابرات هارلی میگوید من هر وقت اجرای زنده میشنوم هرگز عبارات  های فای به ذهنم خطور نمیکند و مثلا این حس رو ندارم که الان Texture صدا خوب است چون در اجرای زنده اصلا این کلمات به ذهن خطور نمیکنند ولی وقتی صدای سیستمی را میشنویم بخاطر محدودیت آن سیستم در مورد اجزای صدایش حرف میزنیم و در مورد محدودیت هایش.

در تجربه شنیداری بیشتر ما ها از سیستم های ارزان تر شروع میکنیم و کم کم با شنیدن صداهای دیگر به تفاوت صداها پی میبریم و درک بهتری از محدودیت های سیستم خود در زمان شنیدن صدای بهتر بدست می آوریم.

با یک کابل معمولی ممکنه مفهوم Air در صدا درک نشه اما وقتی از یک کابل خوب مانند Cardas استفاده میکنیم مفهوم Air رو در صدا درک خواهیم کرد. مثلا وقتی NAD رو به Krell سوئیچ میکنید میتونید بفهمید مفهوم timing چیه و کلا در همین مقایسه هاس که اجزا و پارامترهای صدا درک میشود و audiophile به درک مفاهیم نزدیک میشود.

هر چقدر سیستم های دقیق تر و Musical تر میشنویم و ره یافت ما به صدا بیشتر میشود بهتر از قبل میتوانیم تفاوت ها را درک و به معنی پارامترهای صدا پی ببریم. وقتی سیستمی دقت بیشتری داره با یک تغییر مثل تغییر کابل بلندگو ما تغییر صدای بیشتری از یک سیستم غیر دقیق تر و غیر شفاف تر میشنویم.

یک مثالی رابرت هارلی در کتابش زده میگه یک آدم عادی وقتی به این عکس هایی که از بدن انسان با اشعه ایکس میگیرند نگاه میکنه چیزی دستگیرش نمیشه اما یک رادیولوژیست خیلی اطلاعات از همون عکس استخراج میکنه و مغز یک شنونده با تمرین و شنیدن بیشتر میتونه اطلاعات بیشتری از صدا استخراج کنه.

مسیر مغز در دراز مدت از ماکرو شروع و به میکرو میرسه. کلا مغز اول ماکرو رو دریافت و به سمت میکرو در دراز مدت حرکت میکنه . جالبه هر چقدر از ماکرو به سمت میکرو میریم شاخص های صدا محو تر و درک اونها از عینیت به حس شنیداری منتقل میشه. تنها با گذشت زیاد زمان و در معرض صدا بودن ره یافتی به مغز در مورد میکرو صدا میدهد آنهم شنونده از روی حس اش میتواند تشخیص دهد. یک شنونده حرفه ای تر نسبت به یک شنونده مبتدی تر مقیاس عینیتش بیشتر است و دیگر چیزهایی که خیلی میکرو تر هستند را بشکل حسی درک میکند اما شنونده مبتدی ممکنه حتی مفهوم ساده ای چون شفافیت رو هم با حسش درک کنه و به شکل عینی نتونه به شاخص شفافیت توجه کنه.

فکر میکنم لازم باشه نوشته رومی رو در مورد کتاب Likhnitsky بیارم، ممکنه این کتاب توسط طراح  Audio Note ترجمه بشه و توسط آقای فاطمی نماینده Audio Note در ایران در دسترس علاقه مندان قرار بگیره، منتظر چنین روزی هستم.

رومی توضیحاتی رو تو انجمنش داده که اینجا میتونید بخونید، من بخشی از متن رو اینجا آوردم :

A few year back a Russian audiologist A. Likhnitsky’s published a book “Sound Quality: New approach to testing of the home audio equipment”.  (P&K, 1998) The book has many positive moments and altogether it was a wonderful attempt to bring into our listening audio evaluations and into the general audio practice some light of so necessary there objective rational and sanity.

Looking at the today’s audiophiles, I agree that the semantic and purposeless foolishness with which the audio people operate while they evaluate audio is staggering and the book makes an attempt to structure and to organize thinking about audio evolutions in a very civilized and very humanly-objective fashion. The book was written in Russian. Currently the book is experiencing a second attempt to be translated into English by the efforts of Peter Qvortrup (the Audio Note – UK guy), but knowing how much money/efforts he has commissioned to the project and knowing the intricacy of the Mr. Likhnitsky’s thinking/writing I do not anticipate that Peter will ever succeed. Therefore I presume that the western audiophiles will die in ignorance (just kidding) and will continue to call each other pathetically screaming: “I just bought that amplifier because the damn Patricia Barber was almost in my room!”

Actually, the audio people select audio gismos not just because their listening ignorance or their lack of audio-applied obective methodological ability. Mostly they are just victims and hostages of well-oiled machine of audio-moronisation, namely the Audio Propaganda, that deploys to audio people a set of faulty and totally irrelevant audio evaluation methods, audio objectives, audio critiques, and, weel as it offers to a target market a totally bogus, inner-brewed coordinate system of the audio thinking. It would be even OK if the audio propaganda does it’s bad thing intentionally but unfortunately it is not always the case. The audio propaganda’s composite consciousness itself is a victim of own actions and most of the power-players within audio propaganda are just regrettably feeble and disqualified people.

If you want to make a conclusion about the participants of the audio-power hoodlumhood then do not subscribe to their Internet masquerade or to their hypocritical writings. Meet them, talk with them “live”, sit in their rooms and get your own feeling of what you deal with. You will see how little is there, how afraid they are to maintain their own status-quo and how limited their understanding of what they deal with while they write their audio-doodles. You might be very surprised to meet your “favorite reviewer” and to learn how much idiocy, zombienisation, primitivism and ridiculousness s/he possesses, and particularly when audio is a subject. There is no wonder why most of the audio doodles that they spread around themselves are just the direct depictions of what they are, not to mention the numerous cases of an open untruthfulnees and perpetration of intentional fraud to pubic. I am not even taking about the frequent cases when the audio writers are the factual distributors of the products or the payrolled marketing departments. I am taking about the plan senselessness and stupidity that stuffed practically any audio publication. As an illustration I may recall the quite “popular and famous” reviewer who published a large drooling review about a multi-thousands dollars phonostage. The fun part is that he did not even have a turntable and  therefore he used a reverse-RIAA filtered analog output of his SACD player to feed the phonostage. Well, now get the punch line: when I “gently” informed him that it was not a correct way to drive a phonostage the reviewer replied: “Why not, what would be the difference?” (nd the guy was damn serious!) Is anything else should be said? I would not even go into the fact that the most of the “industry sponsored audio judges” have no necessary cultural level, musical acquaintance and practicly no absolutely-required humane sensitivity in order to evaluate the methods and means of Music reproduction.

Anyhow, what Likhnitsky did with his book was an attempt to take the audio evaluations and audio judgments from the ignorant hands of a commonly moronic audio-oligarchy: manufacturers, dealers, reviewers, editors, audio-heaters and the rest residue of audio industry (not all of them but the dominating majority of them, approximately 80%) and give the correct audio-evaliation keys to wide public, and to help them, to the ordinary listeners, to become the owners of their hobby,  their actions, their judgments, their listening ability and talents.

As I said, the book with more or less success (more frequently “more” then “less”) covers various aspects of audio evaluations. I suspect that the minor drawbacks and the too-simplified approaches that Mr.Likhnitsky did in his book were due to the fact that he targeted wide and mostly none-prepared addressees and therefore we was forced to go as simple and as easy as possible. The book is still mostly too complicated for an average audiophile audio-zombie.

Anyhow, I do not write a review on the book, but would like to embrace it and to offer a comparable vision to one of the strategic aspects of the Mr. Likhnitsky book. I refer to the book’s approach to stricture a listener’s progress into a played material. If to abridge everything tremendously then according to Likhnitsky a process of communicating with the musical messages is a multifaceted process and contains 4 hierarchical levels.

I will be paraphrasing:

At the first level of musical perception a listener deals with Sonic Accuracy: tonal balance, tonal purity, space resolution, sounds clarity, sounds distinctions, sounds details, voices separation, sounds characters, sounds connections, dynamic contrast, dynamic colorations and many others. Most of High End lives within this domain and most of playback systems introduce so much of “sonic contaminations” that any further musical perception remains locked out. In case of none-negative result from the first level and an absents of a sonic dissatisfaction in here a listener’s awareness has no impediments to go further to the second level.

The second level of musical perception has deal with tone and timber. This is much more complex quality related to neutrality, individuality, timber beauty, humanity, harmonization and many others ingredients of music. If a playback system does not screw up at the second level that a listener could fly further.

The third level is an emotional communication with music. At this level a listener deals with the capacity of a system to be transparent for emotional charge of music, musical energy, and the most important the correctness of emotional rendering. Most of the playbacks (if they ever reach this level!) introduce the emotional distortions but should a system still remains the emotionally transparent and “honest” to the source then a listener could go further (assumingly that the source-music has within itself something more then just the tonal and timber contents)

The last, forth level of musical perception, deals with esthetic content of music: the purposefulness of all elements of playback, the connectively of musical events, the meaningfulness of the messages and so on.

What Mr. Likhnitsky offered was very good and he illustrated the subject in his book quite well, offering many useful practical recommendation and examples. However, I consider his vision not exactly accurate, not particularly because it wrong (it is not) but because it is not inclusive and becose it portrays a slightly twisted picture.

Within this thread I will elaborate on my interpretation of the Likhnitsky’s visualization. I’m calling it “Six-Leveled-Listening Benefits”, as I have mentioned it in the description of my playback, (the emails with the questions that I’m receiving since I deployed the description made me to initiate this thread).  The name “Six-Leveled-Listening Benefits” is totally irrelevant and actually it has not six levels but seven levels (more on it – later on). They are the gradual steps that listing awareness takes almost sequentially while we are trying to evaluate the elements of playback.

the Six-Leveled-Listening Benefits™ contains the stratification of the listening experiences within seven virtual levels.

The Six-Leveled-Listening Benefits (I will use SLLB from now) is a totally simulated representation according to which a listening perception identifies the result of a reproduced music listening. This structure could be productively used during evaluations of playback elements or the evaluations of the enter systems, as well as it provide a solid framework for audio semantics and practice. The SLLB is applicable not only within audio. Many of the SLLB’s elements are acting while we’re insisting “live” music well. I would intentionally omit some very minor SLLB alternation that would fit the SLLB model perfectly for “live” musicality and will concentrate explosively on the music reproduction – the audio world.

The Six-Leveled-Listening Benefits (SLLB) implies that our reaction to reproduced music might be explained within 7 boundaries. Those boundaries or levelers are:

1) Static perception
2) Dynamic perception
3) Emotional perception
4) Esthetic perception
5) Ethical perception
6) Re-Creative perception
7) Not Named Level

The first level of listening perception is Static Level. At this level a listener perceives musical information as a collection of the individual sounds and a listening awareness tries to evaluate the “convince-ability” of those sounds. At this level the evaluations of Sound is not necessarily related to the preceding or following sounds/event and instead of Sound a listener deals with an array of  the secluded sounds/tones.

Certainly even the static sounds do have own dynamic/vibrant inner-life but it all included into a definition of Static Sounds at the First Level. Actually the best phrase to describe “it” would be not the Static Sounds but Disconnected or Isolated Sounds.  The ketch in here that any vibrant or “animated” tone without a reference to “something else” is completely irrelevant and has no pointers to its values. The “isolated tone” has just an instant charge, a modal value, it frozen in time and space and it has no relation to anything else. Therefore I called it Static, meaning having no progressive formation.

A listener during his/her playback evaluations at the Static Level pays primary attention to pitches, sharpness, harmonic context, tonal and timber authenticity, neutrality, transient characteristics, granularity and many other properties of reproduced sounds. Interesting that a listener, in fact, do not care about a correctness (how it compare to the “live”) of the reproduced Sounds but rather s/he concerns if s/he does not get within reproduces Sound something else, namely the Alien Sounds. A listener is unable to recognize destroyed sounds but only the original sounds and “something else”. This “something else”, the added superstructure atop the original sounds, is a delta between the  “correct” sounds and what a playback system presents to a listener (the distortions or aberrations). It is important to identify that those distortion/aberrations do not mix inside our consciousness with the  “correct” sounds and they just perceived as a totally separate recognizable-effective entry. So, while evaluating a playback at the Static Level a listener do not search, recognize or analyze the “correct” sounds, as those “correct” sounds are entirely transparent, “consumption-free” and non-detectable by our awareness (at the Static Level but the have own value at the higher levels).  What the listener’s awareness does is scanning the reproduced sound in search for those show-stopping Alien Sounds.

In the audio the primary contributors to Alien Sounds – the Static Level Detectable Differences are individual parts of the audio components, primary the passive parts. Each and single particle of audio signal (to name a few: resistors, capacitors, cables, magnetics, dielectrics, the spaces around the currents flow, electrical and mechanical signatures of active elements, contacts, diaphragms, suspensions and hundreds other contributors) do their contribution to the Sounds and do inject into Sound the Alien Amendments. The Amendments are the signatures of the mechanisms that invoked tem. As the result, we do not recognize the distortions themselves (in my vocabulary “distortions” are not the alternations of Sounds but an appendage of Sound with a residue of the linguistic manipulations) but we hear a language of the conversion processes that created the distortion, or according to the Beach Effect ™ the “language of a parallel process”.

Our listening awareness has an ability to filter out those amendments or to recognize them as the static, fixed amendments with a permanent delta. Sine the delta is acknowledged as delta, the listening awareness activates a static perceptional antidote, that sine it was called help to disregard the amendments or make their presents less influential. The effectiveness of the antidote is in direct dependence how the “language of a parallel process” differ from the language of Reality. If the languages use the similar linguistic algorithms then the effectiveness of the antidote is incredibly high and could completely compensate the presents of the Alien Sounds or the Amendments in Sound at the First Static Level. I have to note that some of the amendments at the Static Level have deep relationship with the amendments that take place at the Second, Dynamic Level (phase-related amendments) and the second-level amendments has way more powerful and more devastating affect to the listening awareness.

Well, if we have such a great ability to tune ourselves out from the Static Alien Sounds then what kind harm they could do? If to simplified everything tremendously and for a sake of illustration to compare our listing awareness with a computer then the awareness runs a multithreaded execution and the amount of cognizant force spent to run one thread take the juice (in case of a computer the processor time and a few other things) out of the parallel threads. Ironically our awareness acts almost similar and while we are filtering ourselves from the Alien Static Sounds we’re masking out  (minimizing) our capacity to be deal (be concentrated) with the content of the original messages.

The audiophiles call the Static Level’s Alien Sounds as the Sonic Colorations. The Colorations from their point of view are the “correct” sounds presented via a prism of Distortions but it is very far form Truth as the natural, original Sound of Reality never mix with the Alien Sounds of a Linguistic of Reality Transformations. Sound and the Sounds are recognized by our awareness separately. The Static Tonal Colorations are practically irrelevant; they have as much unconditional values as the none-existing murky Absolute Tempo in music. Therefore if a person evaluates a playback only at the Static Level then the result is totally extraneous and the person let itself to be engaged into a perpetual chaise of the meaningless and semi-hallucinational Static Level sonic differences.

The contemporary so-called audiophile movement and the entire audio industry concentrated and fully dedicated to analyses, recognition and selling to public the Static Level sonic differences. The audiophiles subscribe to one or to another pattern of Alien Sounds and perpetually chase the patterns as a dog chase own tail. The audio industry well understand this, wonderful for them, marketing situation and deploy an army of the ignorant-heaters-writers, whose audio-awareness are able to operate primary at the First Static Level. Those reviewers, the marketing cheerleaders, continuously propose to the prospective audiophiles-consumers the  “new remedies” or just the new psycho-virtual patterns of the Alien Sounds.

The industry operates quite simple: the most horrible audio element is and the more revolting pattern of the Alien Static Sounds it construct the less audio-intelligent person would be deployed to the “mission”. Any editor of audio publication knows how to mate a misery of a component (need to be “publicly evaluated”) with the personal audio-idiocy and ignorance of a prospective reviewer. The more horrible component get more loaded-with-Mormonism analyst-reviewer, and the “selected” reviewer uses his/her own “talents” to submit the poison-spreading-audio-gismo to public by building a necessary verbal wrap around a product. The consumers, with theirs consciousness operating at the First Static Level, mostly do not even buy into the different patterns at the Alien Static Sounds but they fish for a verbal marketing BS-wrapping around the Alien Static Sounds.

Based upon my experience and my unfortunate observation of those countless audiophiles, the so-called High-End audio has approximately 50% of its participants whose audio objectives concentrated explicitly at the First Static Level. I call them audio-zombies and they pretty much are a boring waste in audio. I have to note that there is no direct relation between the audio-zombies’ audio limitations and their general intellectual or spiritual competence. There is some indirect connection but to cover this subject is not the scope of my current application.

The next post will be covering the Second SLLB’s Level: the Dynamic Level.

The listening perception at Level #2- the Dynamic Level

Well, here is (if you “got” what meant in the article about the First Static Level) a loaded statement: if a listener did not “hear” (acknowledged audio wise) anything at the First Level then the Second Dynamic Level takes it’s turn. The loaded is there was the part “did not hear anything”. Whatever was audio-heard (positive or negative at the First Static Level) was in fact bad. If a listener was audio-wise “unconvinced “ or “impressed” during perceiving Sound at First Level then it means that a playback did something very wrong. Once again: the best possible outcome from the First Level is not hearing any result. BTW, those thousands and thousands pages with the descriptions of what was auditioned from the playbacks written by the industry reviewers who primary operate at the First Listening Level is an indicative evidence now horribly audio performs in the reviewer’s rooms…

The second level of listening perception is a Dynamic Level. This Level includes two sublevels that deal with totally different properties and form my perspective should be evaluated (acknowledged) differently. I intentionally combined those two sublevels into one Dynamic Level: it simplifies the stratification and helps to emphasize that that the sublevels are fundamentally dissimilar form the First Static level.

The Dynamic Sublevel “A” is a Dynamic External Level.  At this level a listener perceives musical information as an arranged sequence of pitches inherited form the First Level and the listener’s awareness recognizes the heard not as the binary succession but as a continues variations of tonal influences.

The Dynamic Sublevel “B” is a Dynamic Internal Level. At this level a listener does not deal directly with the sounds from the First Level but deals with the inner-managerial characteristics of sound reproduction. The Level “B” is a metadata, a structure, a template for the Level “A”.

The next post will look a slightly deeper at what sonic properties are essential and what should be paid attention at the each SubLevel (“A” and “B”) of the Dynamic Level #2

این بحث Subjective Audio گرچه خیلی طولانی شده و هنوز به تعریف مفاهیم صدا نرسیده اما هرچی بنویسم در موردش باز هم بنظرم کم هست. سعی میکنم این مبحث رو کامل کنم و بعد برم سراغ بقیه مطالب.

فعلا مقاله زیر رو بخونید که Steve نوشته ، جالبه :

Good sound / Bad Sound

Feb ۲۰۰۶
by Steve Deckert

During a recent interview with Srajan Ebaen of 6-Moons, he made the observation that many accomplished musicians have rather mediocre stereo gear. Gear that by most audiophiles standards would be considered mid-fi at best.  His explanation was basically that musicians play a participatory role in the experience of music.  They only need a guideline or sketch of the music to recreate it in their minds which explains why when offered hi-end stereo gear to replace their mid-fi components most showed little if any interest.

The point of all this is that during a human beings shift from discovering music as a child to becoming a seasoned audiophile, the participatory or imaginative process employed when enjoying music when you were young (regardless of sound quality) is gradually replaced with expensive audiophile gear.  Srajan accurately points out that this attempt at substitution does not work.  What it does do is create restlessness in audiophiles while they passively wait for their wonder gear to get them off on command.  This is the reason why audiophiles constantly go through different gear in that never ending search for something that they used to have as a child, or can only find at a live concert hall.

These comments help to define the active role of enjoying music to draw a clear contrast with the way a reviewer must listen while writing a review.  Two different things that were never meant to overlap but often audiophiles who are supposed to be enjoying music are instead trying to hear all of the adjectives they read in the reviews.

I believe some of us in the industry can wear both hats because experience has thought us generally not to wear both hats at the same time. After many years of A/B testing components and cables you develop new networks in your brain to process and or hunt for anomalies that do not correspond with the way you imagine it should sound.  It doesn’t take a golden ear to become good at it.  This analytical subroutine that now runs constantly in restless audiophiles did not exist when they were children. Instead it crept up gradually as years of subliminal programming from exposure to audio hype took its toll.    I suspect that these restless audiophiles have not even realized these subroutines now exist in their brains nor would they realize they are counterproductive to experiencing music nor would they know how to turn it on and off.

On of the reasons music is an experience is because you physically go to it.  It typically doesn’t come to you without out at least being actively invited.   If stereo gear is intended to recreate the audio portion of a musical event then listening to it should be approached in a similar way.   Think of a combination of planned and anticipated listening sessions with some spontaneous encounters, never forced.

How well we master the ability to use the correct side of our brain when listening to music on our stereos depends on experience and personality.  It can be hard to turn off the subroutine so that you can have one of those WOW experiences that justify all the money you’ve spent while you listen.    The techniques used will no doubt differ from person to person and are not as important as awareness of where to focus your attention when you listen to music.

The ritual aspect of listening to high fi gear was in part lost when CD players replaced the more precarious hands-on turn table and then when remote controls were invented.   I bring up the key word “ritual” to point out that preparation and anticipation, two fundamental parts of any ritual, are components needed to enjoy music as opposed to finding yourself listening to gear trying to get it to sound better / which is often what happens when you expect a quick fix.

Here’s a few ideas for getting the door of musical ecstasy to open for you:

STEP ONE – Approach each listening session with respect in the knowledge that you don’t know yet if you will have wonderful sound or unexplainably disappointing sound.

STEP TWO – Warm up your gear for 10 to 20 minutes before pushing play, or starting the record.  This lets your mind and your ears still and creates anticipation.  Not to mention lets your amps warm up.

STEP THREE – Tease yourself into it by selecting less aggressive music and playing it at a low volume.  Stay here for at least 5 or 10 minutes minimum.  You can stay here the entire time, there is no pressure to move on.

STEP FOUR – Ask the moment in time your in if it’s okay to proceed.  You really don’t have to ask.  At this point you  either have developed a lust for more or your expecting it to become what it presently is not.   This is where you either get on or step off.   Never force it, it will not happen forced.  Good sound is like a basset hound, you can’t force it to do anything, only ask and wait.

STEP FIVE – If step four failed but you’re not willing to give up (a dangerous bridge over disappointment) you can visualize your situation as a person standing in front of a door.  You can hear the music behind the door and the door is locked.

KEY ONE – To unlock the door you need keys.  The first bunch of keys on your ring can be simply different recordings.  Try them all if you have the patients.

KEY TWO – These are master keys, which are basically components, cables, speakers and room/system layout.  Selecting a key from this group could be something like switching the amplifier or preamplifier.  These are pretty potent keys for unlocking the door because of a little thing called perspective.  If you replace the amplifier with another one you have laying around, one of two things is going to happen.  Either you will like it better than the previous one or you will not.  Regardless of the outcome make sure you listen to it for at least 10 minutes minimum.  If you like the sound better than this 10 minutes could easily turn into an open door.  If you think the sound of the amp is worse, then re-install the original amp and listen to it again.   Now your mind is focused on the things about the amp that are better than the one you just tried and this is usually the point where you suddenly decide you like the way it’s sounding and the door begins to open.

KEY THREE – Retire and try it again some other time.  If you consistently have this problem and are constantly buying and selling gear stop for awhile and quit reading about stereo stuff.  Look at the similarities in the equipment you buy.   Consider trying something ( or everything) completely different to break the pattern.  For some this can be moving from high power systems to low power/high efficiency while for others it could be moving all their present stereo gear into a different room.

LISTENING

Listening to music with the wrong side of your brain is just liking buying gear with your eyes. It’s something everyone including myself must wrestle with from time to time, it’s what makes us human.  As a professional I have developed the ability to listen to gear or music but I can only experience music as good as any other human being. Hearing the subtle phase cues that construct a palpable image and the texture or speed of a given capacitor in a circuit against what I want to be hearing at a given time is highly developed skill. This is a requirement for artistry in equipment design and in equipment review.  However, the less of it you develop the easier it is to enjoy the experience of music on a given stereo system.

Naturally with the jarring shift from left to right brain during a listening experience, it’s logical that you would become distracted and have difficulty re-entering the experience.  Just as it is logical that the better your gear actually sounds against the grand scale of perfection, the less likely it is to do something distracting to the music. That makes it easier for those inflicted audiophiles to reach step 4.

In my work, my mind is the canvas and the amplifiers or speakers (whichever I’m developing at the time) are the paint.  I have to be able to discern the difference between what I have (presently hearing) and what I think it could be at it’s potential. I started out doing this by simply building two of everything and then making small changes to only one and listening for what changed.  ۲۰ years later it has developed into the ability to multitask in real time during an evaluation.  When I listen to a component I hear how it sounds and while listening also hear how I think it could sound almost like a parallel sound track running right next to it.  Then I a few bars at a time I compare the two in my minds ear and define the differences.   As a musician I find similar processes are active when composing music.   I have also noticed that after a few drinks this process becomes modified to leave out what I hear – leaving only the perception of what I think it should sound like.  Not terribly unlike the natural ability we were all born with and lost somewhere in the process of becoming audiophiles.

یکی از برندهای ارزانی که میشناسم nowe audio mono3.5 هست که یک آمپلی فایر ترانزیستوری ده واتی بدون فیدبک منفی هست که تو مد سینگل اندد Class A کار میکنه البته با ماسفت خوب توشیبا.

توشیبا برای Audio ترانزیستورهای خوبی ساخته که ASR Emitter هم از اونها استفاده میکنه و بنظر میرسه میشه صدای خیلی خوبی از nowe شنید البته به این شرط که بلندگوی مناسبی با حساسیت بالای ۹۴ و امپدانس نسبتا خطی بالای ۴ اهم بهش بزنیم.

برندهای زیر هم درخور توجه اند:

Valvet Audio

Sugden Audio

AudioProjekte
