工作上需要把這篇打出英文稿~再翻成中文請大大幫我聽一下... 我已經都打出來了><~~ 畫底線的字是不確定空格處是聽不出來講者是英國人有鼻音~而且似乎講得不是很順...導致我也聽得頗痛苦的XDXD 求有心人幫我聽一下下內容有點多...真的很XXOO... Tony Andrews - "Bad sound is a vexation to the spirit" I want to talk about audio quality and... actually some of the interloop music we’ve been hearing already is a very good example world talked-about. So I’m actually gonna to do a random thing insteead. Rich, could we just put that tune on for a second. I just thought it’d might be a nice idea to good audio quality on. (music on)____ it up a little bit...Thank you very much. So it’s been said that if bad sound was lethal, it would be a leading cause of death and what is saying is that sense of hearing is not given the attention it deserves. It’s underrated. It’s regarded as secondary to sight. You really got to look at the bad accoustics of public spaces, the horrible things that architects and interior designers do without any regard tothe accoustic properties, which of course is so intrinsic to the ambience of the place. It’s not even realized how badly a child’s eduacation is affected by the atrocious quality of the average school classroom. And club world is extremely unusual for the accoustic properties of the space that tens of thousands of what__ audio is gonna be put into, is given due care and attention. So i’d just like to contrast hearing and sight for a moment. Sight makes you look forward. Hearing is appreciated from every direction. Hearing never switches off. It’s always on. You can so easily shut your eyes and there’s another thing about sight which is only one o____ which is the r___ b___, the audio can c__ a__. It’s also about two thousand times moleculars in the sense in a sense of sight in terms of the seperate speed with ___ d_. This general is just not appreciated how this amazing sense strongly affects mood and aldimine. Sadly this general disregardful audio has crept into music and it’s production. So i want to examine where we are, how we got here, what is limiting and maybe what we can do about it, not necessarily in that order. My biggest problem is this dumbing down of audio, because that is prevening us from appreciating music’s full potential, fantasitic transportation of your mind, the depth of emotion and feeling that you can have with music. All these things are shut out from a spot by quality. So, a lot of this as actually...i mean it’s never been great believe me but it’s really got worse since the advent of digital. With digital we’ve got completely inadequate sound v___, bad sound cards, rubbish digital-to-analog converters, analog-to-digital converters. On top of that, we have an indifference to gain structure on the part of many people, particularily DJs. I’m just wondering ..Rich if you would do this sort of things that happen to s__ to a sound when it’s overloaded. So if i was going to be talking like this or not it wouldn’t be much fun, would you? But the number of mixes i’ve seen flat out in the r__ mind, in my time it’s beyond believe and we’re talking people of paying huge amounts of money. It’s not that i’m against digital sound, in fact digital can be much better than analog because we don’t have the hiss, and it’s quite nice but you know the pops and clicks are vital. So it can actually be better. But it’ s very mcuh complicated than analog, and there’s so many different processes and specialize bits of equipment that most of the time it’s going wrong. So what do have to be mindful is trying to get it right. Well, first thing you have to understand is that a sound system is a chain of events and it’s only as good as it’s always been set for years as the w_____ component. Imagine your chain of event is a series of windows, and you’re looking at the city, you only need one dirty window to completely destroy your clarity of you. I’ m afraid this is how it is in audio. If you don’t have a good reference, it;s very hard to evaluate the soli__ integraty of any particular piece of equipment. Because the shortcoming of one peice will mask the performance of another’s. So let’s start with the original microphone input or sound. You obviously need to be clean at the right level and a sufficient resolution to capture all the very low level harmonics that give us sound, it’s richness and it’s character. And some of those things... i want to talk technical for a second, that can be like.. is 30dB down, which basically mean incredibly quiet. But remember we’ve got an incredible audio system in this head and it picks all thses stuff up with you concsious of it or not. So, obviously let’s not use a wave downloaded because...i think this picture speaks the language i’m talking about. The wave...even the CD quality is reasonably sufficient. This is acutally the audio ...the mp3 ..it’s seven of nine actually, that’s what an mp3 audio is like. It’s actually that bad. Youtube and all the rest of it is great for auditioning thing or perhaps founding something you like. But please don’t let it be using it in our professiaonal world. They were born out of the early limitation of the internet. Low bandwidth and expansive storage. Those ays are long behind this. A very unnecesary bad habbit for heaven’s sake let’s abandon the damn things. They’re dreadful. And just we’re around this subject. We’re not particularily as scientists but this thing about mp3 which is a 3 hundred and 20 kilobits per second is supposed to be high quality. A CD ...audio resolutnio is normally measured in sample rate and bit depth. But when it comes to mp3 we don’t talk about that because it would be hard for anyone to talk about it. So it’s measured in kilobits per second and a so-called high quality is 3 hundred and 20. A CD is actually 14 hundred and 40 kilobits per second. To pay proper respect to human hearing, it looks like we need about a minimum of 96 kilohertz persecond and a bit depthh of about 24. This actually translate to about like 4608 kilobits per second. now compare four 4608 with me on the 20. The math isn’t that easy. It’s about seven percent. So basically there are complete amount to insult what god has given us. So a digital hardware, what sort of problems de we get there, well , again we get back to converters, that’s pretty standard actually. We get inaccurate mathematics, we get badly chosen algorithms, we get jittery clocks. It’s a nightmare. Unless they’re alright digital realy isn’t worth playing you a better off with the valve amplifier frankly. But there is an issue with digital and that’s to do with timing or latency. Different digital processes take a different amount of time, and this difference in time is actually incredibly small. But human hearing is actually capable of discerning, s____ is down fifteen to twenty millions of a second. if it is a space between them is longer than that. The auditory system will realize it. If you ‘ve ever listenedo digital,my god, there’s something wrong with it , i cant’t put my figer on it and don’t quite know what it is. It’s probably this mashed up timing and when the brain receives this mixed up timing it gets confused. It disengages spatially and emotionally. It really doesn’t want to go there. I think the picture kind of illustrates what i’m talking about. It’s like a mis registered colored print and we are capable of hearing it and we do. It’ s not audio anymore. it’s noise. So...software mixes sequences f_ players actually have a lot of the same problems is the hardware. You could be pretty sure that if you overuse plug-ins, they’re gonna mash up the sound even more. An awful lot of thses programs have auto limiting and auto gaining, strange EQs in a standard. Going to a global preferences can get rid of them. Because every one of these things means another layer of processing and you’ d be amazed at how much better the sound quality is. We’re saying __it’ll be great but it’ll be better. So...getting to the final mix, please let’ not over-compress everything. We’ ve all heard about loudness war and it was great to see dynamic range day few weeks ago, which is _________, completely nonsense. 4,5years ago,______ there was a great house track that she thought i’m gonna get the CD. So i bought it. It sounded terrible. I got another one and think it was a pirate copy, it was just as bad. So i looked at the waveform, and you can see here, it’s actually flatten off of the top. When i looked at the meters it was point one of a dB before ..well within ___ of it’s life. Evrything ‘s crush to the roof. Cuz it was a solid wall i have to expand this to even show this..all the tops of everything are knocked off. When you get this square things, It’ s a square wave and that all of the most obnoxious sound you can ever hear. So the whole track was ruined by this cli__, nasty sound. The one of the bottom, it’s got a bit of room to breath and the thing is all this destruction just so...we could be louder than the next person’s track on the radio. Afterall , if you want it lound, there’s volume control within reach normally. It’s complete rubbish. And there’s another thing that happens with all the f___ mixes. I would call it, if you like spectral or total inbalance. Human hearing is not equally sensitive to all frquencies. In fact, it’s most sensitive at around 4 kilohertz, which i guess you could call hi-meter. It’s the place where the “s” and “ter”, “ker” and all the definition frequencies are. And it’s also aware of baibes sreaming ___. It is a very attention-grabbing frquency. It’s kind of natural to try to mix everything into it. But what you finish up with is a shriky?, shrill sounds which is actually quite offensive and i just can’t believe it sometime...i do carry earplugs it’s very necessary. But if you want to translate that to a color print, it would be like it’s overemphasized with blue and we’ve completely forgotten about the yellows and the greens. I’m afraid that this is taken as normal and it’s some ri__ throughout the business not just in DJ world, life sound is just appalling. I won’t necessarily get into that eventhough i’ve been making loud speakers for about forty two years now. Will leave that one off the record. This is more important. There’ are always corrupting audios than we’ve actually got time to discuss but it all boils down to one horrible word, distortion. Distortion could be thought of as a twisting of truth. Truth twisted is lies. Nobody wants to listen to lies. So we’re no longer deeply involved in listening, we’re just superficially hearing. The real essence of what all this is put..we’ve only have the big audios for fifty years, not even that . I’m here because i’m absolutely fed up with seeing it go down the drain. It’s being wasted everything that humanity gets is good, finds it way to turn it upside down. When are we ever going to learn? There’s guy called Daniel Levitin and he’s in Canada. He’s written your brain on music and the world in six songs. He’s a professor of psychology and nerosciences. He said that music stimulates more parts of your brain than just about any other known kind of input. Furthermore, he also said that when somebody’s listening to music they don’t like, you get the fight or flight hormone d___ly released. When you’re listening to music you do like, they reward hormone. Dopamine(多巴胺) is released. i would suggest that this also extends to true audio and distortion. Distortion is square wave tha is nasty, it produces adrenaline(腎上腺素). Human are very adaptable. He’s telling me i ’m running out of time, but i won’t stop. Cuz i’m here now. Thank you. (____...) I’m sad to see that recent generation have never heard crystalline, transparent high frquencies. What i have heard is gonna be called audio sandpaper. Thing is we’ve adpated to it, we think that ‘s what it’s supposed to be. It’s not. The whole music business is now infected with this sub-standard audio dBs/dippings – our musical culture, terribly. So if you wish to redefine the DJ, than how about the guardians of our audio sense gape consciousnes arena. It may be. Sorry state of the 21th centry audio. It is bad. Why does it matter? The world seems to be quite happy with it. Well...i’ve got to say that for me, the infinite space ____ inside my mind and i’m sure that many others when they’re really tuning into. Good to stereo material is what so attractive here. Bad quality sound cannot do this becuse you need every link in the chain to be a sufficient resolution to reconstruct the stereo images. And if you don’t do that, then you’re not gonna get there. Imagine being in the land, looking ar a picture of a lovely landscape. And it’s all fuzzy. And actually being in it. That’s the difference as fr as i’m concerned. Involment in multi-dimension audio is transcedent. This is born now by the fact that people are listening to music deeply... have the same brain wave patterns somebody meditating like buddhist monk. This is a fact. The thing about meditation its that it’s quite often and individual experience whereas listening to music is communal and i would suggest thta when we had a magic audio moment, a really good gig, or a wonderful dancefloor experience, it’s not just because of the music and your involvement in it. It’s the fact that we starting to connect with other people in the same dimension. That’s what makes it magic and that’s why this is so precious and why i’m feeling so strong about it. It’s so important because it may be a door to any incredibly badly needed used state of being that we need on earth as soon as possible. A lot of the ...i’ve been talking about audio quality but actually i found a lot of the same concepts applied to music. Of my personal taste is for harmonical tuneful, key-changing, rhythmically satisfying, uplifting music. I believe that music is an expression of the structure and architecture of the universe, so i do not do darkness and chaos. The harmonics arrangements of everything from atomic particles to the planets and the harmony of musical scales illustrates this. natural attractions are harmony and a version?? to discord. Stem from a sense of and a connectedness with the universe. Natural rhythms such as heartbeat, breathing, d__ and the cycle of the seasons are all steeady and life-affirming. Unlike some of today’s rhythms, which if translated to a person’s hearbeat, would probably hospitalized them. Even when brilliant audio, discord , disjointed rhythms and distorted sounds will tend to release stress hormone, adrenaline. This means that they may will be more musical adrenaline junkies in today’s world than there were at the beginings of house music in the 1980s. This music of that time did have all the dopamine releasing requirements. Satisfying rhythms melody, key-changing, etc. This not only gave us enormous excessive of fun, but huge possibilities of communal consciousness. The universe is all vibration and music is part of the great dance of frequencies tuned into that deepest meaning and music might just save the world.
