Optimal Crosstalk Cancellation for Binaural Audio over Two Loudspeakers

Author: Choueiri, E. Y.
Date: 2010

BACCH™ Filters are optimized crosstalk cancellation (XTC) filters that allow 3D audio reproduction over a pair of loudspeakers. They yield maximum crosstalk cancellation level without introducing any spectral coloration to the input signal. An introduction to BACCH™ Filters can be found here.

BACCH™ Filters are at the heart of BACCH™ 3D Sound, Dynasonix, and other emerging technologies from the 3D3A Lab.

This highly technical paper describes most of the basic aspects of BACCH™ Filters (some aspects are not published for propriety reasons).
