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

摘要

An apparatus for generating a decorrelated signal comprising a transient separator (310; 410; 510; 610; 710; 910), a transient decorrelator (320; 420; 520; 620; 720; 920), a second decorrelator (330; 430; 530; 630; 730; 930), a combining unit (340; 440; 540; 640; 740; 940) and a mixer (450; 552; 752; 952), wherein the transient separator (310; 410; 510; 610; 710; 910 is adapted to separate 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. The combining unit (340; 440; 540; 640; 740; 940) and the mixer (450; 552; 752; 952) are arranged so that a decorrelated signal from a combination unit is fed into the mixer (450; 552; 752; 952) as an input signal.
