BACCH{\texttrademark} Filters\ are optimized crosstalk cancellation (XTC) filters that allow 3D audio reproduction over a pair of loudspeakers. They yield a maximum crosstalk cancellation level without introducing any spectral coloration to the input signal. An introduction to\ BACCH{\texttrademark} Filters\ can be found\ here.
BACCH{\texttrademark} Filters\ are at the heart of\ BACCH{\texttrademark} 3D Sound,\ Dynasonix, and other emerging technologies from the\ 3D3A Lab.
This highly technical\ paper\ describes most of the basic aspects of\ BACCH{\texttrademark} Filters\ (some aspects are not published for propriety reasons).
