Zusammenfassung |
AB |
[EN] An audio signal decorrelator (100) for deriving an output audio signal (170) from an input audio signal (112) comprises a frequency analyzer (110) for extracting a first partial signal (120) and a second partial signal (122) from the input audio signal, the first partial signal being descriptive of an audio content in a first audio frequency range, the second partial signal being descriptive of an audio content in a second audio frequency range, the first audio frequency range having higher frequencies compared to the second audio frequency range. The audio signal decorrelator further comprises a partial signal modifier (140) for modifying the first partial signal, to obtain a first processed partial signal (150), and the second partial signal, to obtain a second processed partial signal (152), so that a modulation amplitude of a time variant phase shift or time variant delay applied to the first partial signal is higher than a modulation amplitude of a time variant phase shift or a time variant delay applied to the second partial signal, or for modifying only the first partial signal, so that a time variant phase shift or a time variant delay is applied to the first partial signal. |
