BACCH 3D Sound

 

A Revolutionary Technology for Audiophile-Grade 3D Audio

 

An Introduction through 20 Questions and Answers

 

BACCH3D Sound (also previously called "Pure Stereo 3D Audio" or "Pure Stereo") is a recent breakthrough in audio technology (licensed by Princeton University) that yields unprecedented spatial realism in loudspeakers-based audio playback allowing the listener to hear, through only two loudspeakers, a truly 3D reproduction of a recorded soundfield with uncanny accuracy and detail, and with a level of high tonal and spatial fidelity that is simply unapproachable by even the most expensive and advanced existing high-end audio systems.
