Perfectly, i.e., without imperfections: a BACCH filter has no dynamic range loss, tonal distortion, or any other audible change to your content.

 

Any Content
Any Device

BACCH spatial audio works with any content on any device.

BACCH renders the world’s existing stereo or surround content into spatial audio without remixing or remastering.

Rediscover your favorite music with more vividness, realism, and clarity than you’ve ever heard… on your existing devices.

The BACCH-SP Grand

The flagship implementation of BACCH spatial audio technologies, the BACCH-SP grand from Theoretica Applied Physics is a highly-acclaimed, state-of-the-art digital audio processor that allows the listener to experience spatially accurate 3D sound from a pair of stereo loudspeakers.

BACCH speaker spatial audio

BACCH|SP

Our core technology - an elegant filter for any stereo device that allows any user to experience lifelike spatial audio from stereo or 3D content.

BACCH Headphones spatial audio

BACCH|HP

Headphone spatial audio that actually sounds externalized, or outside your head, for everyone, without any required customization or tuning.

BACCH Phase array spatial audio over multiple speakers

BACCH|X

Multi-user 3D sound using any array of 7+ speakers. Can create personal sound zones as well as clean stereo or 3D images from speakers anywhere in a room or car cabin.

Spatial
Trailblazers

Shortly after his IPO with his previous startup, James Mentz set out searching for the best 3D audio technology in the world. He stumbled upon Professor Edgar Choueiri and his 3D3A Lab at Princeton. After decades of research, Edgar had already won the discerning praise of the audiophile community, but outside of this community, the BACCH technology was widely unknown.

Together, along with Sam Caldwell who serves as VP of Engineering, James and Edgar founded BACCH Labs to bring this promethean spatial audio technology to the commercial market.
