At CEATEC 2023, I examined JVCKENWOOD’s EXOFIELD “Boléro” demo. I’ll clarify EXOFIELD in additional element under, however at a excessive degree, it’s an correct spatial sound rendering expertise.
The Bolero demo consists of visualizing a digital live performance and having fun with the spatial audio high quality. The digital live performance consisted of volumetric scans of 16 members of the New Japan Philharmonic. All members had been positioned to encompass the listener within the demo. The scans had been very detailed, and you could possibly see individuals’s expressions.

To view the digital scene, JVCKENWOOD had Canon MREAL X1 Show with a handles accent, permitting a faster setup than a standard over-the-head equipment. They might have proven a film, however utilizing 3D graphics made issues rather more interactive and distinctive to everybody who tried.
EXOFIELD is a expertise centered on out-of-head localization sound discipline processing, aiming for exact spatial sound rendering. The sort of sound discipline processing is often utilized in Digital Actuality and gaming purposes, the place the positional accuracy of sound is essential, going past a normal sense of “spatial notion.”
In distinction, fundamental spatial notion sometimes employs in-head localization and is prevalent in most gadgets on account of its decrease necessities for computational energy and {hardware}. The 2 applied sciences shouldn’t be confused.
Sometimes, individuals would use EXOFIELD for house leisure functions, which I feel is the first and most evident use case. That’s significantly true in the event you reside in an residence the place it’s difficult to take pleasure in highly effective encompass sound audio system with out your neighbors complaining.
Developed by JVC, EXOFIELD incorporates superior sound applied sciences usually present in high-end house theater programs and premium client electronics. For optimum audio efficiency, EXOFIELD requires a simple, one-time setup that customizes settings for particular person customers.
JVC EXOFIELD is a well known expertise for audio lovers, and this demo is a good way to let attendees expertise the sound it produces. That’s actually the one approach to absolutely expertise the perfect audio applied sciences as a result of it’s powerful to explain and quantify, particularly since that is personalized to every consumer by way of the preliminary setup.
