The Future of Sound Reproduction?

[psychotropic]

Check this out - the technology

Apparently this works pretty much as they describe it and as close as we human beings have gotten to recreating 'live sound' through a recording-reproduction medium.

Here's an excerpt:

"So, how does it work? IOSONO technology combines the use of a large number of loudspeakers with the principle of wave field synthesis to recreate, or synthesize, the complex acoustic wave field of sound emanating from actual objects. Conventional audio systems, by contrast, merely amplify audio signals, which can be compared to displaying images on a TV screen fixed to the wall (or several screens in the case of multichannel audio). With IOSONO, youre no longer looking at a picture on the wall, so to speak, but at an acoustic hologram."

Sounds fascinating!

no one is impressed???

This seems to be related to movie hall sound with multiple speakers, i.e. many more speakers than the 5.1/7.1 we are used to at home.

Since at home we are already positioned in the sweet spot of our equipment (helped along by Audyssey etc), are'nt we already enjoying precise sound steering at home ?

Is this 'movie hall' playing catch-up with 'home theater' for a change (instead of the other way around) ???

 

[psychotropic]

no no, this is a fundamentally different approach to sound reproduction. it's not just about expanding the sweet spot. It's about reproducing a sonic event accurately (or wildly, or however you want to). The potential this affords, and the flexibility is something else.

psychotropic,sounds very promising indeed.but somehow makes sense more in a commercial setting,no?now,if it could be done at home,..would be mindblowing.cheers

Wow!

So since the sound source would be reproduced by the speaker closest (perpendicularly) to it, and then progressively by the adjacent speakers in a radial (or lateral) pattern, the listener would be able to localize point sources regardless of where they're sitting with relation to the speaker array. And sound sources could be identified at any distance behind the actual speaker wall. That's amazing!

Goodbye, sweet spot! And farewell, shallow soundstage! hyeah:

This could be great for music and movies!

shouldnt the recording also be done in the same way with mike positions to get this ?
if older 2 channel recordings need to use this process then it would need some sort of a DSP right ?

 

[psychotropic]

Yeah, I believe the recordings would also need to go through an encoding process for this at the mixing stage. But it would be brilliant if they employed this in cinema sound, and even for music, imagine recreating a concert where you can pinpoint where the guitar player is wherever you're in the room. Gets you closer to that "high fidelity" dream.
