| Abstract | We propose an efficient repeating segment detection approach that doesn't require computation of the distance matrix for the whole song. The proposed framework first extracts audio fingerprints for the whole song. Then,for each time step in the song we perform a query to match a sequence of M fingerprint codewords against the fingerprints of the rest of the song. In order to find a match for the first fingerprint query, a search tree data structure is built with the fingerprints of the rest of the song. For subsequent fingerprint queries for the rest of the song, the matching process dynamically updates the search tree data structure to exclude the M fingerprint codewords corresponding to each time step. For each matching segment, we record the time offset from the query segment. Following the matching process for the whole song, we compute the histogram of the number of matching segments for each offset. The peaks in this histogram correspond to offsets at which matches were found more often than others and can be used to pick out a set of repeating segments. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
