Abstract
A calculation unit for a sound reproduction system includes an input unit, a processor and at least three outputs for controlling at least three transducers of an array. The input unit has the purpose to receive an audio stream to be reproduced using the array, wherein the audio stream has a frequency range. The processor is configured to calculate three individual audio signals to be output using the at least three outputs, such that a first acoustic differential having a second or higher order is generated using the array.
