Title: APPARATUS AND METHOD FOR DETERMINING A PREDETERMINED CHARACTERISTIC RELATED TO A SPECTRAL ENHANCEMENT PROCESSING OF AN AUDIO SIGNAL
Abstract:
An apparatus for determining a predetermined characteristic related to a spectral enhancement processing of an audio signal comprises a deriver configured for obtaining a spectrum of the audio signal and for deriving a local maximum signal from the spectrum. The apparatus comprises a determiner configured for determining a similarity between segments of the local maximum signal and comprises a processor for providing an information indicating that the audio signal comprises the predetermined characteristic dependent on an evaluation of the similarity.
