    Audio set up question

    An acoustics related question - throw out all convenient experience and previous usage.

    Altering an original signal introduces compressed sound and a device's own ability to overcome noise of amplification. Signal to Noise ratio is what this is called, measured in Decibels. A daisy-chain of processors will only be as strong as the lowest SN Ratio. Stereo Separation is also a measured output.

    Stereo Sound is hardly a new concept, in theory there being no mono signal in L & R signal paths, an infinite stereo image and stereo separation dynamic would exist. Any center image would be bound to on-axis speaker response and the volume of all combined ambient sound.

    Yearning to improve natural soundstage, finding two amplifiers bench tested to the same output (in theory possible) and applying the total output with one to the Left speaker(s) and the other to the Right would create widest soundstage images possible. There would be no limitation from an amplifier processing full range Stereo and Mono information.

    Who has working knowledge?

    You just want what exactly? Wider sound stage? Deeper sound stage? This is domestic Hi-Fi you are talking about here?

    Anything limited by a fixed space is what defines the depth or width of a listening environment. Stereo Speaker location as it's governing-factor, why not control any natural spacial effect w/ just two speakers?

    What you are saying is hard to comprehend, or is technically incorrect and you haven't answered any of my questions! What is it you actually want here? One more gobbledy**** post and I'm out.

    You have to enable the secret swearing function first.
    Then you can say all the fun words without being censored.

    But it's not a swear word or even offensive in any way. It's a real word:

    "language that is meaningless or is made unintelligible by excessive use of technical terms."

    Blocking it like that is worse as it makes something innocent look guilty!

    It is not easy to assemble into the attention-span of the OC. Basically I am trying to piss-up a Rope. Can I do it?

    Yeah you are limited to the dynamic range of the mics used in the recording (and the room and other sounds bleeding over).. or how much range the sound engineer has allowed.

    If the audio engineer wants everything loud (like chili peppers album) it might not sound as natural/realistic as you want

    Get a bunch of friends with ghetto-blasters, give them all the same CD (I suggest Umphrey's McGee's latest), start them all at the same time, and have people move about as it's playing. Should create a wide soundstage at some point. Dunno if a bench-test will expose the db ramifications of the subtle electron diffusions. Worth a shot, I think. Let us know how it goes.

    Speakers by the multiples are neat, but two properly amplified speaker components are all that's needed:

    Lemme try this for what it is - Air. Taking the effective displacement of Air by a speaker-driver's one way motor excursion, factoring in this being a stereo signal creates two volumes of Air with common air-pressures (non-stereo mono information). The amplifier has to do alot of work in order to segment the frequencies playing in both L & R speakers and then also create the L & R image, hence the Decibel Equivalent of the loss in total out put from Mono to Stereo.

    "Can't we all just get along?" I once heard over the stereo.

    That is engineering of Sound, important but not the same as the processing of source material into full range sound.

    It takes 18mins for you to assemble sentences like that one?

    Nope - cuddled all night.

    Gentle sobbing was not withheld, I was told to let it all out.

    Is this source material broadcast live, what is it? I think there could be conditioners involved (processing) if you have the left and right side speakers going for the audience (could be part of ambient sound or feedback)

    are you trying to get surround sound with only a stereo speaker set up?

    A 3db decrease in output is mostly a 100% drop in wattage-in-use. A 6db decrease is a perceived to the ear halving of Volume.
    Having 100db in signal to noise and 85db of stereo separation for example is alot of work for a couple of speakers to overcome.

    So, is that yes, or no?

    you must make a centre line down away from the vocal point. Have the right and left speakers at exact distance from you and from each other (i.e if the left one is 10' from the vocal point so must the right one, both pointed towards the vocal point, the sweet spot. Than the Left must be 5' from the centre line as the right one is 5' from the centre line making a equilateral triangle.)

    To get some loudness one must create a sound funnel (like putting your mp3 player in a coffee cup) making the sound directional towards the sweet spot.

    Surround Sound is manipulating time alignment of particular frequencies - it can sound decent but in no way is natural sound. And I would not want to listen to this exclusively so - No.


    Here's the working model of total output and spacial fullness.
