<br> Audio First: <BR> sound quality is the sound quality, many people regarded it with the "sound" confused. .What is called the sound quality? .When you say that when good quality pair of shoes. .You mean must be fit, comfortable, durable, not the good shape it does not look good, time is not fashionable. .Similarly, when you say a hi-fi sound quality is good, bad, and you did not at the level of how it, positioning, such as can be, but specifically refers to this device "does not Naiting resistance!" .If resistance is not durable, do not fit together the same. .A good quality equipment, outstanding performance is its comfortable, Naiting. .You do not have to explore it sounds comfortable, Naiting reason, it is a matter experts, you just use your ears to judge on the line. .Some equipment fierce and powerful, is fast and resolving power is also strong, but not durable to listen to, it may be sound quality issues. .A good audio equipment, the sound should be like a good voice, makes one hundred non-greasy. .Perhaps you or I say that very abstract. .In actual fact, I can cite to illustrate the real column. .When you mention fabric, you will say: the quality of this material well. .When you eat steak, you would say: a good piece of steak meat. .When you praise a child, would say: the child's qualified good. .So, when you listen to an audio equipment or a musical instrument, you will say: it's sound quality is beautiful. .From these examples, you can clearly know that "quality" is inherent in nature. .Sound noble, good, beautiful to represent the good nature of this equipment, it is to sound very comfortable. .I can say that quality audio equipment is the most important part, so I put it in the first to be. .<BR> <BR> Audio Second: <BR> <BR> tone color tone is the sound. .In English, the sound quality (TONEQUALITY) and tone (TIMBRE or TONECOLOR) see at a glance the meaning is not the same thing. .But in Chinese, the sound quality and sound are often use and abuse. .We often hear: that the violin sounds really cool, it really warm violin sound to say so, this means in terms of the violin's sound. .Sounds like the same light, there is a color, but it is not with the eyes see, but to the ears to hear. .Typically, the more warm tone sounds more soft; sound more more hard cold voice. .Too soft or too hard, of course not very good. .Sometimes, the sound can also use the "noble", "United States" and other words to describe, basically it is one of nature. .However, like fabric in general, refers to its cloth material, fabric and color is that its color, which is obvious during the boundary. .The comments in audio equipment, sound like the color in general, is its unique color. .Some equipment yellowish tone, and some partial white, some cool, or even worry you can say that it is a little blue Mao. .In short, the audio equipment like musical instruments in general, the more you almost can not escape the fact that sound more beautiful. .A two million dollar violin can sound beautiful and it has a golden luster; and a thousand NT dollars may sound like a violin its faded painting. .Although each person different point of view, but "United States" still has a people recognize the "consensus", you can not say that a person is overturned nose "of beauty"; the same thing you can not say that the equipment cold blue tone is beautiful .. .This is our common understanding of the beauty of sound. .<BR> <BR> Third sound: high, medium and low sense of the frequency distribution of the amount of control <BR> <BR> this project is very easy to understand, but also very easy to produce words to convey a misunderstanding. .How do you say? .We will say: This is too treble horn, bass too. .This is the high, medium and low frequency distribution of flu. .The problem is that if the bandwidth from 20Hz to 20KHz to points only three paragraphs, then it would have a "not accurate" confusion. .In the end of your bass is there? .More low? .To make the text more accurately described, it is necessary to be 20Hz-20kHz bandwidth segments. .According to the U.S. sub-TAS and Stereophile method is simple, they have high, medium and low subdivided into three small pieces each, that is, into a "lower intermediate frequency, intermediate frequency, high frequency," points system. .The points system is like equal temperament in general, very regulated. .However, the Chinese people who used to have some minor problems with translation, such as "low frequency" we call the "low frequency" or "low frequency"? .Then the higher frequency it? ."High frequency" do? .For the Chinese, foreigners would not work in this sub-method. .So long ago I refer to the instrument bandwidth, and the orchestra to sound the call, 20Hz-20KHz frequency will be divided into very low frequency, low frequency, low frequency, medium frequency, high frequency, high frequency, very high frequency such as seven-segment .. .This seven-segment line with the general term used to refer to the Chinese people, and easy to remember, not confusion. .ELF <BR> <BR> <BR> from 20Hz-40Hz octave I call this a very low frequency. .The small band of musical instruments, only about double bass, bass, bassoon, Tuba number, organ, piano and other instruments to achieve that low range. .Since this very low frequency range is not the most beautiful instrument, so very few composers to write notes so low. .Pop music unless it is deliberately arranged the electronic synthesizer, or in terms of very low frequency for audio fans really useful. .Some people mistake one thing, said that while the instrument is not so low pitch, but pitch harmonic can be as low as below. .In fact, this is not correct, because the instrument's pitch is the lowest tone of the sound, the sound will only double, triple, quadruple, five times ... so climb high, and not have the sound down. .It's like you will be a string tension, string length of the vibration frequency is the pitch, half, third, fourth, one fifth of the chord ... so the vibration is harmonic. .The sum is the pitch and harmonics of the sound. .In other words, even if the violin and flute pitch (pitch) the same sound will have different performance. .<BR> <BR> Low <BR> <BR> frequencies from 40Hz-80Hz this is called low frequency. .What instruments do the band? .Drums, double bass, cello, bass, bassoon, bassoon, bass stretching number, bass clarinet, No. Tuba, French Horn and so on. .This constitutes a vigorous low-frequency band is based on the big hero. .Typically, most people will mistakenly think this band is extremely low, because it sounds very very low. .If too little feeling in the band, rich, and will not be feeling surging; and it will result in the high-frequency, high frequency of the outstanding balance to make the sound out, not durable listen. .<BR> <BR> <BR> <BR> From the low-frequency between 80Hz-160Hz, as in the low frequency. .This band is Taiwan's biggest headache for some audio fans, because it is caused by natural ears humming culprit. .Why this band particularly vulnerable to the peak of it? .This small room length, width and height dimensions related. .Most of the people in order to remove this annoying peak, devoting himself to absorb the band, so that the ear Buzhi Yu roaring contingent. .Unfortunately, when your ears will not be humming sound then, the bottom of the low frequency and above with the IF probably have been presented in the absorption of low frequency depression status, and make the sound thinner, the lack of luxurious feeling. .Even more unfortunately, because most people believe that the disappearance of the peak is right this case. .This is rich, many voices are not at home one of the reasons. .The band's musical instruments, including the earlier mentioned low frequency instruments. .Yes, timpani and bass have to add the phrase. .<BR> <BR> Frequency from 160Hz-1280Hz <BR> <BR> across three octaves (320Hz, 640Hz, 1280Hz) frequency between the IF I call. .The band almost all the instruments, voices are included now, so is the most important bands. .Readers range of instruments occurred most misunderstood here. .For example, most of the violin in the band range, but most people mistakenly think that it is high; do not think that the high soprano range, in general, she also was the highest in the intermediate frequency range the upper limit only. .From the above description, you must also understand that this frequency is in how important sound. .As long as this frequency of depression, the performance of the sound soon became thin. .Sometimes this thin is easily interpreted as "false rally." .I believe there are many fans are in the audio frequency depression without being aware of the situation. .The importance of this band as well as two-way speakers from the crossover point to analyze. .General two-way speaker's crossover 2500Hz or 3000Hz mostly about that, 2500Hz or above the tweeter is responsible for, 2500Hz responsible for the following Central and woofer. .This is 1280Hz 2500Hz lasts twice, that is, for fear of the woofer at the students at the intermediate frequency limit too much crossover distortion, the designers all the crossover frequency increased to twice the upper limit of Office, so .As a result, the perfect frequency to be issued by the Central woofer. .If that is correct, the tweeter what to do with it? .If you ever put your ear close to the tweeter, you'll hear a "hissing" sound, and that is where most of the overtones. .If there is no hissing sound tweeter, woofer with a single to sing in the music, it must be dark unbearable. .Of course, if a three-way design speakers, most of this frequency will be included in the midrange monomer. .<BR> <BR> <BR> <BR> High frequency from 1280Hz-2560Hz as in the high-frequency. .What instruments do the band? .About a quarter of the violin in this high range, upper limit of the viola, flute, clarinet, oboe, high range, the lower half of range piccolo, cymbals, triangle and so on. .Please note that a small speaker is not in this band domain. .In fact, it is easy to identify high-frequency, high-range group as long as the strings and wood pipes are in the high frequency range. .The band will be mistaken for a lot of people high, so please pay special attention. .<BR> <BR> Frequency <BR> <BR> this from 2560Hz-5120Hz frequency domain, what I call the high frequency. .This frequency domain for musical instruments is concerned, is already involved in a few opportunities. .Because in addition to the range limit violin, piano, piccolo high ranges, the remaining instruments are mostly not appear in this band. .From the speaker's crossover point, we can find that all of this appears in the frequency domain in the tweeter. .As I said earlier, when you put your ear close to the tweeter, you have not heard the sound of musical instruments, but a hissing sound. .From the performance of the tweeter, you can once again that rarely issued tweeter instrument or vocal pitch, it's just the high-power harmonic pitch just issued. .<BR> <BR> <BR> <BR> Extremely high frequency from 5120Hz-20000Hz such a wide frequency band, known as a very high frequency. .You can see from high-frequency instrument appears to have very few facts, the learned best accommodated in a very high frequency is a harmonic instruments and vocals. .Most generally the higher overtones of musical instruments at the smaller energy, in other words, the tweeter to create very sharp, clearly a very subtle tone regeneration. .From here, occurred in a single manufacturing problems speaker thing, that is, how to best of both worlds? .What is a "co-existence?" .Have you ever thought, if a tweeter to clear all the subtle overtones regeneration, regardless of all the designed small current can push the diaphragm, then the same by this tweeter is responsible for high-frequency and frequency of large energy .distortion is likely to be often in the state, because these two very high-frequency energy than the band's big too much. .It is also currently on the market very high number of speakers is very clear, but easily one of the reasons tend to be harsh. .You remember the previous SpentdorSP-1 speakers? .It is a three-way design, the three sound way? .The woofer, tweeter, treble single three-way. .Monomer is responsible for the ultra-high sound frequencies above 13000Hz. .I remember that a lot of people "understand" why the SP-1 has high sound monomer, while the voice is so soft it? .Should be very sharp fishes it! .Now I think you should know it! .SP-1 design focus is to make the tweeter without distortion, and extremely high frequency and can recycling. .This is the SP-1 sound very comfortable, with music of one of the reasons. .Understanding of high, medium and low frequency sub-laws, we went outside to discuss the amount of a sense of "control." .Feeling in <BR> is depends on the size of course, that is, we say: more treble, less bass and so on. .The control is usually multi-finger "on the low frequency and high frequency," the control. .Some equipment, loose bass, and some are flexible. .We will say that the latter have low-frequency control. .Some equipment can be captivated high frequency, it will not have ears Biao uncomfortable, we say good high-frequency control. .Please note that the amount of feeling in the band does not represent the true quality equipment, equipment for the interaction between the amount of flu with is important. .The quality of the control device itself can be said to be the superior and inferior. .<BR> <BR> Fourth sound: the sound field performance <BR> <BR> "sound field" in the end is what? .In the United States, "SoundField" and "SoundStage" are two terms. ."SoundField" refers to the sound filled the room; "SoundStage" refers specifically to the arrangement of the band on stage (including the wide, deep, high, low). .In Taiwan, our so-called "sound field" actually means "SoundStage" is concerned, because both the "sound stage" or "mixer" can not let the words too literally. .As for the "SoundField", we have already replaced with another term, that is, "sense of space." .So when we referred to "the shape of the sound field" when the equipment is that your band are arranged in the shape regeneration. .Frequency response curve due to the uneven distribution and directional speakers, sound reflection conditions of the room, some of the sound field is concave, some are wider than the depth; some depth greater than width. .Some of the sound field shape is boxy, not concave. .The sound stage, the regeneration of different shapes, I called the shape of the sound field. .Of course the best shape of the sound field with the record intact when found. .Here, I want to make a remarkable place: the time of recording live performances, the band is wider than the depth of arrangement; but in the studio, often for sound effects, change the arrangement of the orchestra, usually in depth would pull .long, especially the percussion will be beyond this number. .Thus, it is not that we have seen in the concert hall in order. ., Discerning readers and commentators must be aware of. .<BR> <BR> <BR> <BR> Sound field position in addition to "shape", the sound field as well as "location" issue. .This includes the sound field before and after, high, low. .<BR> <BR> Some equipment would make the whole sound field approximation to the listener; some are back. .Some sounds sound field will find floating in the air; some are like a sat watching the second floor of the Concert Hall stage in general. .Will form a sound field position for many reasons, like the speaker placement and the frequency response of the uniform or not, are all significant factors. .An ideal sound field position should do? .Double bass, cello sound came out from the lower, the position of the violin and cello higher than the double bass; if the recording orchestra arrangement of the former low after the high, the tone before the lower floor should also have occurred after the appearance of a high. .As the brass is very likely higher position. .As the height of the sound field? .Often when you are sitting in two head-height should be slightly lower height of the sound field. .In other words, should be in line of sight above the violin, cello, double bass should be under the line of sight. .Brass and violin at least high or higher. .As for the sound field before and after the position should be there? .Should be in the "horn front line" starting next extension. .Of course, the ideal location of the sound field is not easy to obtain, because it is great to listen to software but also the relationship. .Typically, along the line from the horn extends back more easily obtained, however, can not be "retracted" too much. .<BR> <BR> <BR> <BR> The width of the sound field often hear fans boasted: "I not only beyond the sound field speaker, arrived in two wide side walls, and even 破墙 out." Outsiders listening in this sentence .years, is ridiculous. .To my ears, only a little exaggeration. .I think many fans have this kind of audio experience, do not me to go waste your breath. .In general, the width of the sound field can be arrived wide side wall. .As 破墙 out, I am afraid to rely on a little imagination. .At least to me, I want "with eyes to see" what counts is where the sound field outside the wall of the things I can not see, I'm not sure it is there. .So, I in fact the width of the sound field only within the walls of my only. .<BR> <BR> <BR> <BR> Depth of the sound field which is what we usually call "deep sense", and now it attributed to the depth of the sound field. .Why are not the same as before, layering it with the positioning being tied for it? .Because the level and location are not talking about the sound field, and depth perception is still in the scope of the sound field, so I changed it to "sound the depth of field" instead of "depth perception" called. .And "width of the sound field", many people would say that his family had 破墙 out the depth of the sound field, deep into the street. .This of course is only to satisfy their own adjective. .The real "sound field depth" refers to the sound field in front line instruments and instruments from the last line. .In other words, it most likely refers to the violin and drums, the distance between the timpani. ."Wide right next door, deep off the street" that should be included in the back say "sense of space" in the. .Some equipment or the environment because of excessive low-frequency or low frequency, so the location of the timpani drum and will forward setting, this time, of course, the depth of the sound field is poor. .Another instance, some shrinking back position of the sound field, the result be mistaken for a good depth of sound field, it is wrong. .I believe that, you just grasp the "violin to the timpani, bass drum the distance between" this sentence can not go wrong has. .<BR> <BR> Audio Fifth: the sound a sense of weight <BR> <BR> density and the density of the so-called sound like a kilogram of cotton and one kilogram of iron in general, of course, the density of iron is much greater. .Thus, although both weight the same, but the weight of iron to give people a sense of much greater. .Density voice sounded feel? .Strings have a sense of viscosity, thick, full band music, percussion strikes will have the feeling of vibrations in the air. .All the instruments and voices should have a sense of weight. .However, most fans are not sound very good sense of sound density and weight. .I guess this feeling with the power supply is sufficient and in-band, low band full on. .The density and weight of sound, good sense of what good is it? .For instruments and voices sound more solid and more like a more stable real. .<BR> <BR> Sound Sixth: <BR> <BR> clarity is almost a sense of transparency can be felt, but not explained the term. .Some devices may sound very clarity, while others cast a Wuban like, as long as there is a replacement person must have experienced this feeling. .Sense of transparency is the "sound twenty to" a very important aspect, because if poor sense of transparency, then the joint will also affect the rest of the judge. .The best feeling is soft and transparent, sound does not fatigue the ears; poor sense of transparency such as eye injury in the sun, although clearly seen, but very distracting. .Most of the audio equipment can not achieve clear and soft and the degree of transparency, but only only with clear it. .If you can achieve "clear and soft," then the value of the pieces of equipment, I am afraid that is not low. .<BR> <BR> Sound Seventh: <BR> <BR> layering layering is very easy to understand, it is a musical instrument-to-back rows of the interval can clear regeneration. .To television, the dark gray and black to tell the difference, then there is the sense of hierarchy. .Sound is no exception, the arrangement will not mix with orchestra is a good layering. .Even worse, we want to hear the space between the instruments and musical instruments, this will be the best sense of depth. .<BR> <BR> Audio Eighth: positioning a sense of <BR> <BR> the name suggests, a sense of positioning is to position "be there." .No sense of focus backward positioning, imaging and sense to not force poor positioning, equipment positioning phase distortion will lead to a drift; even direct audio space, the proportion of poor and reflected sound (usually too high-frequency reflection .) will also lead to the location are not allowed. .An example: hot in the summer, the asphalt will take gas. .At this point if you go on the road, you will find images of objects float. .It sounds like we will drift positioning instrument inside the case. .If you have astigmatism forget to wear glasses, that is the concrete expression of good sense of positioning. .In short, poor sense of orientation may be caused by many reasons, whether it is how we formed, we require that the instrument or the human voice to be embossed and clear "fixed" there should not move when not to move, do not .When the chaos can not be chaos. .<BR> <BR> Audio Ninth: live live influenza <BR> <BR> sense of the so-called transient response can be said, the sense of speed, strength contrast on the other side. .It lets you listen to music from a very lively, not dead. .This is music an important factor in whether or not nice, like a great conductor, music director can be full of life; and bad music is often confused command dead. .This is the sense of live music. .<BR> <BR> Audio X: Results as a sense of strength and body <BR> <BR> the name suggests, is to end like the power of audio-visual illusory ability to condense into solid; in other words, let the sound or .instruments show a three-dimensional physical ability. .In the past, I put it under "physical sense" in the. .Later, I carefully thought about, that the use of imaging and force meaning to accommodate a more complete, so now would be to end the sense of like force and shape. .Results like the power of a good audio equipment makes video more relief, more three-dimensional. .I often say that is the shadow of better audio and video profiles. .<BR> <BR> Audio XI: resolving power <BR> <BR> most understand the term most Yung, who played all know that the camera lens resolving power between good and bad; watching TV people know their own TV .Can a black hair analysis is the resolving power was in no way mixed with a good performance. .Good sound equipment, even if more subtle, more complex things can be expressed clearly, which is resolving power. .In fact, more with the dark-level detail is also clearly the result of resolving power, which like the sense of space can also be incorporated into the sound field in terms of the same. .But the resolving power and can not represent all of the details of the regeneration and layering. .For example, the level-to-back rows of sense is not all caused by the resolving power; Furthermore, if it will be layered into the resolving power, it can not be done on the individual's clear explanations of terms. .Therefore, I have separated as much as possible for as long as readers know "Twenty sound to" difficult to divide between the relationship to each other have it. .In general, if the subtle changes (low) can show very clearly that this resolving power, of course good equipment. .Since there are low resolving power, then there is no high resolving power when it? .Of course! .When in extreme bursting can resolve everything very clearly, that is, high resolving power. .<BR> <BR> Audio XII: speed and the transient response <BR> <BR> In fact, the sense of speed is the result of transient response, but also the rise time and slew rate equipment, specific performance. .The foreigners will usually say that the transient response without that sense of speed. .However, the language used in Taiwan is the sense of speed. .For Laos, the sense of speed is more easily understood than the transient response. .Basically, these two terms is that in terms of equipment, the speed of the reaction. .I think this will not have to do more to explain. .<BR> <BR> Audio XIII: the strength of contrast and contrast dynamic contrast <BR> <BR> strength can also be said that dynamic contrast is a foreigner, that is, the contrast between loud and low voice. .<BR> General, the strength of the contrast can be divided into "strong contrast" the strength of the contrast with the "minimal contrast," the strength of the contrast. .We often say that great classical music refers to the dynamic sound of its biggest and most significant contrast whisper; and rock music loud though, but it is not large fluctuations in the size of the sound, so we say it out loud though, but the dynamic contrast is not large .. .What is very small compared dynamic contrast it? .Is very close to the strength of the fine contrast. .Compare the strength of this subtle waves like water waves as far as to see fixed, close look to know that it is always fine in the fluctuations. .Strength compared with the most simple and obvious to say that is this: a great contrast between the strength of the waves beat the rocky shore; minimal contrast is the strength of the wind blowing the water fluctuations. .<BR> <BR> Audio XIV: the size of instruments and vocals in the end the proportion of <BR> <BR> line of musical instruments, how much body to be considered right? .In the end the human voice to be a ray such as chain? .Or to rich, meat? .This problem has been plaguing audio fans. .Idealists believe that the actual band size should be scaled down into the listening room at home. .In fact, it is not possible. .Let me cite a simple example better. .When playing the piano and violin sonatas, the piano than violin body does not know how many times (the volume versa). .If the recording does not increase the volume of the violin, piano, violin often masked (live music is often the case). .Therefore, recording, recording will deliberately strike a balance violin volume. .Again comes to the Philharmonic performance with the violin concerto, if scaled down completely, then the violin's sound should not be more small fine, not what we heard on the CD so clear, strong. .Therefore, the correct "proportion of the size of instruments and voices," not blindly act according narrow, but the music should be made in accordance with the size of a reasonable proportion. .Musical instrument case, the human voice is no different. .In fact, the size of instruments and vocal proportion of the most noteworthy problem is not scaled down or not, but because of the frequency response curve distortions caused by the misunderstanding. .For example, your serious about the room in the 100Hz peak, then it will knock timpani particularly large, especially strong and; cello, double bass is no different. .This is the real error ratio. .Therefore, in assessing writing, "the size of instruments and the proportion of the human voice", you should pay special attention to the frequency response curve of the impact of distortions. .<BR> <BR> Audio XV: the texture of instruments and voices, the air being <BR> <BR> "texture" rather abstract term, we often say that a good texture of wood furniture, leather sofa set .good texture; or the marble texture good. .From this example, we can understand the so-called "texture" Beijing is the object "material nature." .However, we are not here to say that the texture of sound quality, but the musical touch that instant action against the texture of what happened. .So when we say: "violin string texture good rub", it means "it is very like the recording violin." .When we say: "cymbal percussion texture very good", that "it like a real knock." .Conversely, when we think "violin string texture rub enough" is said, "It is not true." .Thus, we can clearly understand that the so-called texture also means "fidelity." .Laser discs at launch, we all feel like the voice of the violin is that it is not rubbed string texture. .The "physical sense" is more easy to understand, when we listen to clarinet playing, we feel it's good form, that is "fidelity" of the kind. .In short, both a sense of texture and form is the "fax it or not" synonymous. .As for the "air sense" what is it? .When we describe the pull-outs, keyboard, percussion instruments, we use the word "certain musical texture good." .However, when we describe the instrument, we usually do not have "texture" word, but with "air sense", that is the feeling of blowing. .Better picture of that, "air sense" refers to the feeling of sound vibration, and texture of most of the "contact" after the moment of feeling. .Of course, in addition to bowed string group string texture when rubbed, but it also generated in the air as well String "air sense." .<BR> <BR> Audio XVI: details about renewable <BR> <BR> details of the instrument refers to the details of the fine church sound recording space recycling and all the noise. .Details of a regeneration of the amount of audio equipment is easy to compare them by ABTest. .Why do some more equipment, the details of the regeneration of it? .I think that with low distortion, high signal to noise ratio, high sensitivity, resolving power, a sense of transparency and so on. .Details of the equipment sounds less flat boring: more details of the equipment it interesting. .A good audio equipment, of course, the details of the regeneration of immense wealth. .<BR> <BR> Audio seventeenth: the sense of space <BR> If a stereo system (including equipment and space) to "float out of the sound field," then it must also "see" the sense of space. .Please note that I used the "see" rather than "heard." .Really good performance, the sound field and space is definitely a sense of "see", not only "hear" it. .What is the sense of space? .That is, three-dimensional physical size of the recording sites. .To be able to be fully reflected the sense of space, excellent detail regeneration is absolutely necessary, especially the "Church Music" regeneration. .Can even say that if the court can not hear the full sound, then the "sense of space" was not the complete regeneration of it. .What is "Church Music"? .Church Music and "reverb" often has been confused. .Most people mistake "Church Music" is the "reverb." .In fact, this is two different things. .The English Church sound is Ambience, Reverb English is Reverberation. .Ambience is the intent of the surrounding environment or atmosphere, later to be extended for the concert hall sound in the hall. .From the "atmosphere" word, we can understand it is surrounded by the music around us the details. .In addition to outside emotional significance, Ambience otherwise a rational explanation, it is narrow ear for the first time that reflected the incoming sound. .In other words, by the first sound reflection sound and true then the time delay, we can "feel" the size of hall space. .Therefore, if we can not hear the Church in the software sound, we can not "see" the sense of space? ."Reverberation" in the general interpretation, of course, can be said is reflective tone. .However, the reverb time for a more stringent definition that refers to the sound of a burst occurs, the sound energy decay to the original one in a million (60dB) the length of time. .In other words, we would usually say: "This concert hall reverb really rich, really beautiful," but rather that a longer shorter reverb. .Conversely, we should not say: "The Hall of Church Music is too short," but rather said: "The concert hall of the church sound really rich and really natural." .<BR> <BR> Audio eighteenth: the overall balance <BR> <BR> each audio equipment and command and control are the same band, it should seek an overall balance. .This is like an orchestra, everybody is a master soloist, but everyone came up with the spotlight, do not listen to the interpretation of the command, this way despite the high standard of individual performance, but the overall balance of a certain band is poor. .This is not a good band. .Similarly, an audio equipment in the preceding seventeen elements are very good, but if you can not do this seventeen elements of a delicate balance, it certainly is not durable listen. .At this point, no matter how high resolving power, no matter how strong or weak compared to no avail. .On this, we can not scale to measure out, to distinguish more than just the overall balance of the orchestra concert to distinguish good and bad in general, there is only a rich listening experience on their own to determine the. .In addition, the overall balance that's still high, medium and low frequency distribution of the appropriate amount of sense. .For example, we mentioned that one of the better low-frequency basis. .The so-called low-frequency low-frequency foundation is created in the music strong, stable state. .Most music fans have hope the music is very thick, rich, and do not want more than high frequency, low frequency, which leads to top-heavy situation. .This reasonably high, medium and low frequency of flu that is what I said 旳 overall balance. .Sound equipment and good overall balance will Naiting, which is commonly referred to musical. .In passing sentence, when you do speaker placement, the first is to get the whole balance. .Do not order the performance of the sound field, at the expense of a strong intermediate frequency and low frequency. .What I mean is: If your speaker is too far away from the wall when the low will be insufficient, then the speakers should be placed against the wall. .Nineteenth <BR> <BR> audio: equipment <BR> <BR> each individual audio equipment and human beings in general, has its own personality. .Some devices may sound like a gentleman, a bit like Grease; like some gentle lady, like some passionate Carmen. .Because different personalities, so will be in the mix on the same event such as marriage, proceed with caution. .Two hot temper, together with the equipment will allow you to endure. .Conversely, two warm water, but also slow with sudden death with your doctor. .Therefore, individual cognitive
