Abstract
For calculating a fingerprint of an audio signal, the audio signal is divided into subsequent blocks of samples. For the subsequent blocks, one fingerprint value each is calculated, wherein fingerprint samples of subsequent blocks are compared. Based on whether the fingerprint value of a block is higher than the fingerprint value of a subsequent block or not, a binary value is assigned, wherein information about a sequence of binary values is output as fingerprint for the audio signal.
