Patent ID: 6951977

Claim:
A device for smoothing a melody line segment, comprising a provider for providing a time/spectral representation of the audio signal, wherein the provider for providing is implemented such that it provides a time/spectral representation that comprises a spectral band with a sequence of spectral values for each of a plurality of spectral components and that the time/spectral representation in each spectral band comprises a spectral value for each time section of a sequence of time sections of the audio signal; a determinater for determining, on the basis of the time/spectral representation of the audio signal, a melody line segment of the audio signal that respectively uniquely associates one spectral component to each time section of a section of the sequence of time sections; and a tone smoother which is implemented to associate a number to each time section of the melody segment such that for all groups of directly adjacent time sections, that have the same spectral component associated to the same by the melody line segment, the numbers associated to the directly neighboring time sections are different numbers from one up to the number of the directly neighboring time sections, for each spectral component associated with one of the time sections of the melody line segment, add up the numbers of those groups to which time sections of the same the respective spectral component is associated by the melody line segment, determine a smoothing spectral component as the spectral component for which the greatest summing-up results; change the melody line segment by associating the certain smoothing spectral component to each time section of the melody line segment.
