BACCH Laboratories Inc.

Founded 2017

Convert stereo and surround audio tracks into realistic spatial sound across consumer devices

You can use BACCH Labs to transform standard stereo or multichannel audio into immersive three-dimensional spatial soundscapes without modifying original master recordings. The technology uses digital crosstalk cancellation filters licensed from Princeton University to project sound outside standard speaker boundaries and headphones. Audio engineers and hardware manufacturers can integrate BACCH algorithms into smart speakers, vehicle cabins, mobile hardware, and virtual reality gear. It creates accurate spatial sound reproduction across two speakers, separates personal sound zones in multi-speaker setups, and produces natural externalized headphone listening.
