Abstract:
Disclosed is a method and a system to determine an audio precompensation controller for an associated sound generating system including a total of N≧2 loudspeakers, each having a loudspeaker input. The audio precompensation controller has a number L≧1 inputs for L input signals and N outputs for N controller output signals, one to each loudspeaker. For each one of at least a subset of the N loudspeaker inputs, an impulse response is estimated at each measurement position. For each one of the L input signal(s), a selected one of the N loudspeakers is specified as a primary loudspeaker and a selected subset S including at least one of the N loudspeakers as support loudspeaker(s).
