Title: Client server system retrieving music based on melody inputted by sound and client computer
Inventor: NAGATA AKIMINE
IPC: G10L17/26
Filed: 2000-12-19
Abstract: PROBLEM TO BE SOLVED: To provide the melody retrieval technology of a sound input system by a client server system, which guides a user to sound-input correct melody, prevents a wasteful retrieval instruction from being given to a melody database retrieval processing means as much as possible and can usefully use the function of the system at the most. SOLUTION: The sound input analysis means of a client analyzes a sound signal with timing made by a metronome as a reference in a sound input reception process and calculates the synchronous degree of the pause of a musical time sequential change and metronome timing and gives an instruction to reinput sound to the user when the synchronous degree does not satisfy the reference. When the synchronous degree reaches the reference, a query including melody piece data obtained by expressing the musical time sequential change of the sound signal in an electronic music system is generated. The server retrieves a melody database with melody piece data in the query as a key, detects music and generates a retrieval report.
