Last Autumn I received an email out of the blue from a Professor Edgar Choueiri who introduced himself thus:
Dear Mr. Weiss,
I am the director of the 3-D Audio and Applied Acoustics (3D3A) Lab at Princeton University, where my research group has been focusing on binaural audio reproduction through two loudspeakers using optimized crosstalk cancellation filters.
Over the past few years, I have developed a method for deriving crosstalk cancellation filters (called BACCH filters) that are optimized to minimize spectral coloration while maximizing crosstalk cancellation between two speakers and the contra-lateral ears of the listener. … Read the full article
