Test for similarity of unknown sample to songs in the database (Shazam). In this figure, it was seen that a random 20-s sample clip was taken from a song in the database and was queried using the Shazam algorithm. This test was done to show and compare the number of matches the query had to each song in the library. Results showed that the number of matches for the corresponding song was large compared to the matches of the query found in other songs in the database. This justified the reliability of the Shazam algorithm
