Science Fiction Time ?

My favorite is the transducer (i.e. speaker) the size of a quarter that emits hyper frequencies (around 250 khz) that, when mixed with other hyper-freqs, magically reduce to human range (20-20K) and can be "focused" into a local "hearing zone" so you all can watch home theater, at full volume, on you couch while the baby sleeps in the next room. This is actual technology owned by a company in (last I heard) Poway CA.

Digital room conditioning, as you put it, is already here. SigTech, Snell, Meridian, TacT, etc.

I envision a recreation of a live musical performance, displayed as a 3-d , moving, holographic image, right in your living room, from some type of hologram projector reading a massive block of computer memory as the storage device.
The complete performance with the musicians performing in the original environment they recorded in, is projected in a 3 dimensional reality in your living room ,as you sit in your favorite listening chair.
Audio quality is 98% of actually being there. Speakers are eliminated as a device has been invented which modulates the surrounding air in your room to recreate an almost exact analogy of the pressure waves generated in the original recording venue.

Listening rooms injected with floating gaseous particles each containing a microscopic loudspeaker, the signal from the amp beamed to each particle, the position of each particle kept in position by an electro-magnetic force field.

Storage formats that are not medium based, i.e. MP3, that are small, incredibly high quality(better than DVD-A, and SACD).

SACD and DVD-A are a fads based of technology that is quickly getting to its EOL, why should we still be using such limited, delicate physical media. You should just be able to queue up an album from remote storage arrays which have every song concievable already on them.... well maybe not, thanks to the RIAA

heh, i could set up an array like that in in less than a week, the technology already exists....but i'd get sue'd for the rest of my life

you know how it goes...profit before progress
