Abstract:
1. An apparatus for generating a decorrelated signal comprising: a receiving unit for receiving phase information; a transient separator for separating an input signal into a first signal component and into a second signal component such that the first signal component comprises transient signal portions of the input signal and such that the second signal component comprises non-transient signal portions of the input signal; a transient decorrelator for decorrelating the first signal component according to a first decorrelation method to acquire a first decorrelated signal component; a further second decorrelator for decorrelating the second signal component according to a second decorrelation method to acquire a second decorrelated signal component, wherein the second decorrelation method is different from the first decorrelation method; and a combining unit for combining the first decorrelated signal component and the second decorrelated signal component to acquire a decorrelated output signal; wherein the transient decorrelator is adapted to apply the phase information to the first signal component.
