Isn't stereo enough?

    Hello,

    I have been told that since we only have two ears,

    one should be able to create a 3 dimentional sound

    with just two speakers, adjusting the frequencies

    of a sound to place it. In other words, we only hear

    things in 3 dimentions because they have different

    pitch characteristics which we interpret as placing

    them in 3-d space.

    This being the case, why bother with more than two

    speakers and a sub-woofer? Are there products out

    there that take a 6.1 (or similar signal) and process

    it so that it sounds three dimentional when coming out

    of two speakers? This way you could focus on getting

    two really good quality speakers and a sub-woofer.

    Two speakers would also go over better with my wife,

    as I am working on our bed room system. I plan to

    put the speakers into the walls if I use more than

    ones up front, but that is significant work I would

    like to avoid, if it isn't really needed.

    Perhaps the technology isn't there yet in consumer

    products to do what I want to do?

    Thanks.

    -William

    Ever since it's conception "Stereo" was always meant to be

    3 full range front channels (Left Center and Right) but due

    to WAF and other Marketing logistics what we got was called

    2 Channel Stero. Companies such as Bose tout that you can

    create "Seemingly full 3D sound effects" from only "2 Speakers"

    Go listen to them and let your ears be the judge, jury and

    most likely the executioner.

    Phsycoacoustics (tricking the ears) only works in "perfect"

    rooms with superior acoustical layout and design. In the real

    world it hardly works.

    I guess using headphones is an exapmle of "perfect"
    conditions, as this can be seen at Disney.
    So if I go 6.1 I wonder if putting the speakers into
    the walls will pose a problem since the TV is in a
    corner of the room like this and we watch from bed
    I imagine speakers at [​IMG] locations and Sub at [​IMG] behind
    TV:

    That is the finest ASCII room I've ever seen!

    Something like Q-Sounds's algorithm can work extraordinarily well. Better, even, than sending signals to a bunch of speakers in disparate acoustic micro-environments. Needs to be encoded that way, though.

    Headphones offer the potential of the best surround experience of all when listening to a binaural recording. Again, needs to be recorded with that intent.

    The Ascii room is nice but the holes in the wall have to effect the acuostics so how [​IMG]

    That is very similar to the setup I have in my living room with the exception of the couch. My couch is aligned with the front stage and TV. The rears are not aligned, but they are in either corner, a few feet behind the listener. It works quite well.

    Listen to a 5.1 setup vs a stereo setup and you will understand why multi-channel is great. BUT, I still listen to most of my music in stereo... Movies sound best in a multi-channel setup, hands down. You do NOT need a perfect room to "fool" your ears, only a properly calibrated system.

    Jon Sez---"That is the finest ASCII room I've ever seen!"

    Well, that gave me a good chuckle, lough

    out loud funny.

    I did something simialr many years ago

    in a 2 channel Apogee duetta set-up. But

    it was done because of the dipole nature

    the Ribbons and paticualr room acoustics.

    Meanwhile, back at the ranch.

    This is an old polemic 2 channel VS 3 Channel

    VS 5.1.....10.1 Ambisonics, ambiphonics and

    now Chesky Brothers variation on a theme of

    THX. From your diagram, a 2-channel rig is

    gonna have a very difficult time re-creating

    a sonic image of the recording venue. Stick

    with the typical 5.1 setup.
