Apparatus for decoding a signal comprising transients using a combining unit and a mixer

A method for decoding a signal comprising:

• separating an apparatus 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 apparatus input signal and such that the second signal component comprises non-transient signal portions of the apparatus input signal;
• decorrelating the first signal component by a transient decorrelator according to a first decorrelation method to acquire a first decorrelated signal component;
• decorrelating the second signal component by a further second decorrelator 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;
• combining the first decorrelated signal component and the second decorrelated signal component to acquire a decorrelated combination signal;
• and
• generating output signals based on a mixing rule, the decorrelated combination signal and the apparatus input signal.

A non-transitory computer-readable medium comprising a computer program implementing a method for decoding a signal, said method comprising:

• separating an apparatus 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 apparatus input signal and such that the second signal component comprises non-transient signal portions of the apparatus input signal;
• decorrelating the first signal component by a transient decorrelator according to a first decorrelation method to acquire a first decorrelated signal component;
• decorrelating the second signal component by a further second decorrelator 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;
• combining the first decorrelated signal component and the second decorrelated signal component to acquire a decorrelated combination signal;
• and
• generating output signals based on a mixing rule, the decorrelated combination signal and the apparatus input signal.
