Query by Tapping: A New Paradigm for Content-based Music Retrieval from Acoustic Input

[[abstract]]This paper presents a query by tapping” system, which represents a new paradigm for CBMRAI (content-based music retrieval via acoustic input) systems. Most CBMRAI systems take the user acoustic input in the format of singing or humming, and the timing or beat information (durations of notes) is sometimes discarded during the retrieval process in order to save computation. Our query by tapping” mechanism, on the other hand, takes the user input in the format of tapping on the microphone and the extracted duration of notes is then used to retrieve the intended song in the database. Since there is no singing or humming, no pitch information is used in the retrieval process at all. Most people would think that it is hard to do music retrieval via beat information alone. However, our experiments demonstrate that beat information is also an effective feature in the sense that it can be used to retrieve the intended song from a large collection of music database with a satisfactory recognition rate.[[fileno]]2030226030029[[department]]資訊工程學
