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

摘要

An apparatus for generating a decorrelated signal including a transient separator, a transient decorrelator, a second decorrelator, a combining unit and a mixer, wherein the transient separator is adapted to separate an input signal into a first signal component and into a second signal component such that the first signal component includes transient signal portions of the input signal and such that the second signal component includes non-transient signal portions of the input signal. The combining unit and the mixer are arranged so that a decorrelated signal from a combination unit is fed into the mixer as an input signal.

1. An apparatus for decoding a signal comprising:
a transient separator for 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 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 obtain a second decorrelated signal component, wherein the second decorrelation method is different from the first decorrelation method; a combining unit for combining the first decorrelated signal component and the second decorrelated signal component to acquire a decorrelated combination signal; and a mixer, being adapted to receive mixer input signals and being adapted to generate output signals based on the mixer input signals and a mixing rule; wherein the combining unit and the mixer are arranged so that the decorrelated combination signal is fed into the mixer as a first mixer input signal and that the apparatus input signal or a signal derived from the apparatus input signal is fed into the mixer as a second mixer input signal.
