Method for determining a characteristic data record for a data signal

According to the method according to the invention for determining a characteristic data set ("fingerprint") for a sound signal, the sound signal itself is searched through for characteritsic locations, and these characetristics locations are used for producing a characteritsic data set. For this the frequency spectrum is evaluated over a time interval, subdivided into frequency bands and averaged over each frequency band into a value. The fingerprint then consists of data which has been obtained from these values after possible further averagings, wherein only data is included which belongs to certain time segments
