1. An apparatus for providing a fingerprint of an input signal,
wherein the apparatus is configured to determine intensity values for a plurality of time-frequency regions of the input signal,
wherein the apparatus is configured to compare the intensity values associated with different time-frequency regions of the plurality of time-frequency regions, to acquire individual values of the fingerprint based on the comparison of intensity values associated with two time-frequency regions,
wherein the plurality of time-frequency regions are defined by a rotating kernel, rotating around a spectral bin of a time-frequency representation of the input signal,
wherein the rotating kernel extends over at least two spectral bins of the time-frequency representation of the input signal.
