Searching system and method of audio fingerprint by index information

An audio fingerprint searching system and method using index information are provided to reduce searching time by generating index based on statistical characteristics of audio fingerprint of an audio file. An audio fingerprint searching system using index information comprises an index process part(3), a DB group(2), and an audio fingerprint searching device(1). The index process part extracts an audio fingerprint from an audio file and transmits the audio fingerprint and information about music to a corresponding DB. The DB group generates index based on statistical characteristics of the audio fingerprint, and stores position information for matching the index, audio fingerprint, and music information continuously. The audio fingerprint searching device creates new index based on statistical characteristics of an audio fingerprint of newly input audio file, and searches information about corresponding music for the new audio file by searching the new index from the DB group.
