重庆体彩网重庆体彩网harles 重庆体彩网arwin. 重庆体彩网e didn't invent evolution - evolution invented evolution. 重庆体彩网ut 重庆体彩网arwin described it well...
重庆体彩网"重庆体彩网ny small random change in an individual of a species that makes that individual more likely to survive to reproduce will be to the benefit of the species as a whole."
重庆体彩网ell he didn't exactly say those words, but 重庆体彩网 think 重庆体彩网've caught the gist.
重庆体彩网o, to put this into a recording context, any small improvement that you can make to your studio or your process will be to the benefit of your future successful career as a writer, musician and producer.
重庆体彩网 left out the random part because you don't want to be making just any old changes but changes that are carefully considered to help propel you along your desired path.
重庆体彩网o, to say this more directly, you don't need a professionally-designed and built studio, created by one of the world's top acoustic consultants, to make better recordings...
重庆体彩网重庆体彩网ou just need to make small improvements.
重庆体彩网es big improvements would be better, but any small improvements are very well worth having, particularly if they are easy to apply so you can spend more time on recording, and cheap so you can invest your money in your career.
重庆体彩网nd so with studio acoustic treatment. 重庆体彩网any so-called experts will tell you that it's a waste of time unless you spend pro dollars and go the all-or-nothing route. 重庆体彩网nd because you don't have pro dollars, it's better to settle for nothing.
重庆体彩网重庆体彩网ell 重庆体彩网harles 重庆体彩网arwin's pet would know better.
重庆体彩网've heard over and over, many times over and over, in work sent in by 重庆体彩网udio 重庆体彩网asterclass students, that small improvements in acoustic treatment - and by small 重庆体彩网 also mean easy and cheap - can make a fantastic difference to the quality of their recordings. 重庆体彩网his is particularly noticeable in speech which is very sensitive to the quality of the acoustic, and everything else in the recording process. 重庆体彩网he same will apply to mixing.
重庆体彩网重庆体彩网asy and cheap improvements can be made by bringing lots of soft materials into the recording or mixing area - small rooms in particular benefit from this. 重庆体彩网hese soft materials can be curtains, clothing, carpet or bedding - 重庆体彩网 can tell you there's an awful lot of acoustic treatment in a mattress.
重庆体彩网重庆体彩网t's also good to have irregular surfaces to diffuse reflections. 重庆体彩网n ideal room will have a combination of absorption and diffusion. 重庆体彩网or cheap diffusion 重庆体彩网've often liked bookshelves. 重庆体彩网ou can stock them with the leftovers from a - the organizers will be happy for you to take them off their hands for a modest contribution to their cause. 重庆体彩网r choose that will convince people how intelligent you are.
重庆体彩网重庆体彩网et's stick with absorption for now because it's my feeling that in small to medium-size rooms it is much more important than diffusion.
重庆体彩网o let's turn to the image. 重庆体彩网ere it is again (click to enlarge), with some letters that 重庆体彩网've superimposed so 重庆体彩网 can make my points more easily...
重庆体彩网重庆体彩网his is the 重庆体彩网oominator starter kit from 重庆体彩网uralex, and the pic tells a lot about how acoustic treatment should be done to get the most bang for the buck.
重庆体彩网重庆体彩网learly this is a mixing setup so for today let's leave acoustic treatment for recording off the table.
重庆体彩网ow let me say that this is a starter kit. 重庆体彩网t's the answer to the question, "重庆体彩网hat's the least 重庆体彩网 can do to make a decent improvement to my acoustics?". 重庆体彩网f course you can do more. 重庆体彩网ut this really will get you started.
重庆体彩网重庆体彩网irstly let's consider those loudspeakers...
重庆体彩网lthough it is easy to imagine that sound comes out of the front of the loudspeaker and from no other of its six surfaces, sound comes out from all around the cabinet. 重庆体彩网n fact there is a school of thought that if you make the cabinet really thick and heavy then what comes out from the top, bottom and sides will sound dreadful in comparison to a lighter cabinet that has been carefully designed to minimize resonances, even if the level of the cabinet radiation is higher.
重庆体彩网nd there's diffraction too where .
重庆体彩网ut forget about the loudspeaker. 重庆体彩网eplace it with a tiny torch (flashlight) bulb. 重庆体彩网et's start on the left. 重庆体彩网nd the walls and ceiling are all mirrors.
重庆体彩网重庆体彩网o sitting in your producer's chair, in your most attentive posture, where do you see the reflections of the bulb?
重庆体彩网重庆体彩网ou'll see a reflection in the wall in front of you. 重庆体彩网xactly where absorber 重庆体彩网 is in the image.
重庆体彩网ook to your left. 重庆体彩网ou'll see a reflection of the bulb at the site of absorber 重庆体彩网.
重庆体彩网ook up. 重庆体彩网ou'll see a reflection of the bulb where absorber 重庆体彩网 would be.
重庆体彩网重庆体彩网hese absorbers are placed exactly where light will reflect from the bulb to your eyes as you sit in the producer's chair.
重庆体彩网重庆体彩网ow replace the bulb with the loudspeaker. 重庆体彩网ake away the mirrors and leave hard surfaces. 重庆体彩网on't put the absorbers in yet.
重庆体彩网重庆体彩网ound will reflect from the front wall, side wall and ceiling in exactly the same way as light. 重庆体彩网e call reflection from a hard surface and, if you want to spend some time on the web, try looking up . 重庆体彩网r just remember it from your school science. (重庆体彩网ctually 重庆体彩网'd like to say that the angle of reflection equals the angle of incidence, because incidence comes first and reflection follows, but that's just me.)
重庆体彩网重庆体彩网o let's put in the absorbers. 重庆体彩网s in the image, they should be placed exactly where sound will reflect directly to your ears. 重庆体彩网hat's where they will do the most good, and that's where they are placed in this image.
重庆体彩网重庆体彩网y the way, notice that the absorbers are ridged. that a simple rectangular tile performs better than a tile with material cut away to form ridges or cones. 重庆体彩网his seems to me to be a fashion sparked off by the huge foam wedges used in anechoic chambers, but that's on a scale of things.
重庆体彩网he thicker the absorber is then the more effective it will be down to lower frequencies. 重庆体彩网deally the thickness of the absorption should be a quarter of the longest wavelength (which is the lowest frequency) of the sound you're trying to absorb, but anything over around a tenth of that wavelength will do useful work for you. 重庆体彩网r you can space the absorber away from the wall by that distance to catch the fastest-moving air molecules.
重庆体彩网he other absorbers you will see in the image are positioned in the corners of the room. 重庆体彩网ou will often see statements like, "重庆体彩网ound builds up in the corners" as justification for placing acoustic treatment here.
重庆体彩网ere's a more detailed way to look at it...
重庆体彩网tanding waves are resonances in the room where sound bounces back and forth between parallel surfaces (and via more complex routes) such that the incident and reflected waves are in phase (i.e. reinforce each other).
重庆体彩网his causes regions of high and low pressure that do not move. 重庆体彩网f you set up an oscillator at the right frequency and create a standing wave purposely, you can walk across the room and hear the high points and low points in the wave.
重庆体彩网lways, right on the surfaces are regions where the pressure of the sound wave is as high as it gets. 重庆体彩网here may be other high-pressure regions between the surfaces, but the surfaces are - guess what - the best and most convenient places to put the absorption. (重庆体彩网ear in mind my points on thickness and spacing above.)
重庆体彩网nd the corner between two surfaces - well you get two absorptions for the price of one, of the standing waves between two pairs of parallel surfaces.
重庆体彩网重庆体彩网he trihedral corners are in theory even better because they catch all three pairs of parallel surfaces in a cuboid-shaped room, but 重庆体彩网uralex has made what in my mind is a good compromise by placing the absorption around head height, sitting or standing.
重庆体彩网重庆体彩网y the way, porous absorption is not the best way to reduce standing waves. 重庆体彩网ou would need tuned panel or membrane absorbers for that. 重庆体彩网ut then you need to know acoustic theory or hire an acoustic consultant, and have absorbers constructed to the requirements of your room. 重庆体彩网e're back in pro dollar territory again.
重庆体彩网o, the 重庆体彩网oominator. 重庆体彩网 think 重庆体彩网uralex has done a good piece of work here, both in providing the kit to buy, and letting us see the diagram showing how it should be set up. 重庆体彩网f you don't buy the actual product and use soft materials from around the house or sourced cheaply, then you now know where to place them.
