Spherical sound

Get the 'all round' sound experience

Sick of listening to your DVD's in 5.1 sound, or even 6.1. Tired of waiting for 8.1???

I propose a revolutionary new system for the complete audio experience. A Chair that is supported in the center of a hollow sphere made of speakers. When sound is recorded, it must be recorded very accurtaley obviously, with a sensor recording distance, latitude and longditude, onto a program that can then replicate the same sound into the speakersphere.

Aesthetically speaking, I had envisioned the chair being held in place with thin, yet sturdy poles, or being suspended from the ceiling of the sphere. Obviously this would be rather harsh on the eye, so modifications would have to be made to make it look professional.

There would obviously be a section where the television would be blocking the sound from the sphere, but I'm sure the rest of the sphere would more than make up for it.

       How many speakers are you expecting there to be in this sphere?   

       If any more than, say 10 speakers, how do you propose to record and transmit the music to these speakers?   

       I would suggest that Dolby Digital 7.1 surround sound does a very good job at creating an immersive experience, with only 7 speakers and a subwoofer.

       Each point on the sphere would have a co-ordinate that relates to the postion in the real world, when recorded. when recording, a mic would have to be used (invented) that can judge 360 degree sound, and has sensors all over it so different sensors on the surface of the mic (say a sphere shape itself) can record how much sound reaches the sensors (thousands on the surface of the mic)   

       Once the information has been stored as to how much sound reached each sensor on the mic, that should be able to be recreated in the speakersphere, by having each mini speaker in the sphere correlate to a certain sensor on the mic.   

       I think the biggest problem would be how to deal with different frequencies, not the recording, as lower frequency sounds need bigger speakers. A bridge I'm hoping we can attempt to build togther

       Baked, but not likely widely known to exist.

       With a suitable array of 4 microphones in a tetragon configuration and sufficiently powerful computing, the exact direction of a sound can be determined. If an array of this type is centered at the camera lens, this might actually be possible.By advancing each sound by the time it takes to travel from speaker to ear, you could get a near exact representation of sound placement. I envision a setup of a large sphere-shaped room with at least 12, preferably 20 speakers, located at the vertices or faces of a dodecahedron.

       [Freefall]: How do you propose to distribute suitable quality 20-channel sound?
Cedar Park, Oct 21 2003
  

       I once read about an experiment whereby a wall with hundreds of microphones was placed in front of an orchestra and miles away (by telephone) a wall with hundreds of speakers was assembled and reproduced the sound to an audience. Apparently the effect was impressive. Though I cant help thinking telephone is not a suitable media.
