REQ: Bacch Labs u-Bacch

u-BACCH is a universal BACCH filter tuned solely by the angle of the speakers.
u-BACCH simply requires user (or device) input of the angle of the speakers compared to the listener to create a spatial audio soundstage extremely close to that of a measured, BACCH-SP filter.

This allows any user to create a spatial soundstage in seconds, simply by tuning by ear.
