load adaptive phase calibration (LAPC)

The LAPC function, Load Adaptive Phase Calibration (LAPC), is a procedure for improving the room sound of stereo systems.

In the LAPC procedure, an acoustic test signal is generated and radiated from the loudspeaker. The reproduction quality is analyzed by measuring the amplitude and phase behavior, and an optimization algorithm is derived from this. The sound quality, which depends on the impedance behavior of the loudspeaker, is adaptively influenced by the algorithm calculated in a digitalsignal processing by changing the amplitude and phase behavior.
