A little more on the topic of tuning, sound and recording
You may not know this but everything that is in the live room making sound you should be able to hear if within the microphone pattern and range, including the size of the room. The job of the speakers and the room is to recreate a 3 dimensional landscape of what was put in the recording.
So how big is a soundstage?
A lot of times when you are listening you see a soundstage picture in front of you that seems a certain size, but when you think about a recording itself isn't it much bigger than what I am hearing between my speakers? And shouldn't the sound be all around me instead of just in front? The answer is yes on both counts. If you put on a set of headphones you would hear music all around you and of course the sound goes far beyond the speakers placement. The same thing is true with your room. If your limited to sound only as wide as the speakers and a little space behind the speakers you are shutting down the speaker to room interface, and stopping the room from playing it's role as the natural space amplifier that it is.
Your amplifier is the first of three amplifiers in the chain. Amp, speakers and room.
It's a big mistake not to think of your room as an amplifier. The sound pressure in the room is what you hear. And if you look at the pattern of sound you can cleary see that it's natural for the sound waves to amplify.
Sometimes when talking and showing pictures about sound people stop a little short in showing the movement, size and shape of sound. You see it's very important when tuning in the sound of your room that you are picturing the soundwaves like above and not below.
Sound is round and when bent out of shape is looking to get round (spherical) again. Spherical is the natural shape of energy. It's a huge problem if you try to treat your room as if sound waves are straight lines and you are treating reflections. Here's something that might help.
below are the pickup patterns of microphones
As you can see there is nothing straight line about the acoustical energy being gathered by the microphones.
now here's the output of a driver
Again there is nothing straight line about the actual signal being played and then being re-played. The microphone and speaker have the same relationships with their rooms. On the beginning end the signal is round and on the delivery, round as well.
Almost seems shocking doesn't it, hearing someone in audio say your hearing straight line reflections? Sound is anything but straight lines.
Let me do a little myth breaking in a couple more areas. It's extremely important in this industry that we spend our time on the oraganizing of energy and not the distorting of it.
In this particular case I think it's a good idea to look at what diffusion is according to Wikipedia. http://en.wikipedia.org/wiki/Diffusion
"In the audiophile world many myths have been created, the good of acoustical difussion is one of them. First off they could have used a better word cause diffusion refers more of spreading out, and the way some acoustical companies are doing "their" form of diffusion is to make waves disembodied. The audiophile world talks about killing waves or causing them to break up. Where does this help the sound? The idea of an acoustical space is to support the sound pressure not distroy it." mg VH1 interview 2004
take a look
Above you see audiophile diffusion in action. How are the waves shaped coming out of the speakers? Spherical. What happens to the waves when they hit a diffuse wall?
this times a couple hundred
the uniformity is lost
Above you can see the fight going on between the space and the speakers. This is acoustical distortion. What should be happening is the room helping the music to project by developing an organized support system that the listener can control the dimentions of. Below is the begining of acoustical organizing.
Dampening the room can be just as bad.
As bad as diffusion is, the oposite end of acoustics "dampening" can cause just as much distortion. The idea of the room as amplifier falls apart the more direct dampening you have in the room. The way to control a room without losing acoustical signal is to implement an acoustical baricade system. Simply put, don't have the speaker created soundwaves absorbed without an acoustical membrane between the dampening and the listener.
below, you can see the soundwaves not making it to the listener before being distorted
above, the waves make it to the listener in balance and with the correct amount of gain...RoomTuning instead of room killing
A baricade treatment will burn more energy and leave the listening area sounding like the material of the membrane that is being used to keep the burn away from the listener. Control without loosing content.
a common mistake
You don't want to kill the sound of the room with heavy drapes or dampened acoustical deadeners as this will leave the music lifeless and dull, missing vital parts of the recording. You also don't want to trap the sound leaving acoustical holes in the soundstage and dead spots. The best way to treat the room is to use a balanced approach with baricade treatments that act like stop signs for the extra waves, without creating other acoustical problems.
Our rooms are to play the role of the studio or hall, playing back what was originally recorded. In order to do this we want to make our space into our own personal mini concert hall. This is done best by using technologies that preserve an restore the sound.
