Band-Assembled Crosstalk-Cancellation Hierarchy

It all started when…

Dr. Edgar Choueiri, a plasma physicist and Professor of Princeton University, delved into the world of 3D audio with one mission: crack the code on cross-talk cancellation. Within his research lab over the past decade, he was able to perfect cross-talk-cancellation of two loudspeakers to produce true 3D audio that replicates any binaurally recorded or virtually constructed soundscape perfectly. Since then, a host of other 3D audio technologies have spawned as well. This led to the recent creation of BACCH (Binaural Audio Cross-talk Cancellation Hierarchy) Labs in 2017, to implement and spread this technology globally.

So what do we do?

BACCH Labs is a technology licensing company that handles the IP portfolio produced by Princeton University’s 3D3A Laboratory, as well as other related IP, in the area of 3D (spatial) audio, for applications in various fields including: virtual reality, augmented reality, automotive audio, consumer audio, gaming, pro audio, cinema, teleconferencing, and mobile devices.

Our goal is to bring cutting-edge audio technologies from the research laboratory to the commercial sector to provide our partners and licensees with breakthrough solutions and powerful hardware and software tools that are truly innovative and disruptive.
