Our algorithm is different.
Four Audio’s beamsteering algorithm differs fundamentally from the conventional approach, which uses beam parameters (inclination, aperture angle) to try to sound an area as evenly as possible. Instead, the user defines the listening areas as well as the position and orientation of the loudspeaker. The algorithm then iteratively calculates FIR filters for the individual loudspeaker channels to achieve the best possible uniform sound distribution on the listener surface(s). Furthermore, blocking surfaces can be defined, which may be exposed to as little sound as possible (e.g. the ceiling or the rear wall). Another upstream FIR filter then ensures that the frequency response on the listening area corresponds to the user’s wishes (Auto EQ). The algorithm can also be applied to curved arrays.
