A computer system is configured for performing audio matching. The computer system includes a client terminal and a server. The client terminal includes a classifier, a first landmark extraction module, a first encoder module and an integration module. The classifier is configured for estimating an identification difficulty. The first landmark extraction module is configured for determining the number of times for landmark extraction, and for extracting first landmarks. The first encoder module is configured for encoding the first landmarks. The server includes a second landmark extraction module, a second encoder module, a hash table, a table-lookup module, an analysis module and a decision module. The second landmark extraction module is configured for extracting second landmarks. The second encoder module is configured for encoding the second landmarks. The table-lookup module is configured for performing a table lookup. The decision module is configured for determining an audio matching result.

The present disclosure provides a method for recognition. The method includes inputting a melody and obtaining pitch tracking information of the melody; obtaining beat information of the melody; determining a clarity value according to the pitch tracking information; implementing a first comparison process first to filter a first set of candidate songs from a database and then implementing a second comparison process to filter a second set of candidate songs from the first set of candidate songs if the clarity value is larger than a predetermined threshold; and determining at least one final candidate song from the second set of candidate songs.
