stereo systems. In the LAPC procedure, an acoustic test signal is generated and radiated from the loudspeaker. The reproduction quality is analysed by measuring the amplitude and phase behaviour and an optimisation algorithm is derived from this. The sound quality, which depends on the impedance behaviour of the loudspeaker, is adaptively influenced by the algorithm calculated in a digital signal processing by changing the amplitude and phase behaviour.
