摘要：
An apparatus for determining a pitch information on the basis of an audio signal. The apparatus is configured to obtain a similarity value being associated with a given pair of portions of the audio signal having a given time shift, wherein the apparatus is configured to choose a length of signal portions of the audio signal used to obtain the similarity value for the given time shift in dependence on the given time shift and where the apparatus is configured to choose the length of the signal portions to be linearly dependent on the given time shift, within a tolerance of ±1 sample.
