PROBLEM TO BE SOLVED: To improve accuracy in music transcription.SOLUTION: In a music transcription process executed by an information processing device, sound waveform data is acquired (S310) to specify object sound data (S320). On the basis of the specified object sound data, object sound frequency transition and object sound acoustic pressure transition are derived (S330, S340). Note data contained in specific sound data that includes musical tone frequency transition having a similarity of a first reference value or higher relative to the object sound frequency transition and musical tone acoustic pressure transition having a similarity of a second reference value or higher relative to the object sound acoustic pressure transition is acquired from a storage device in which the specific sound data is stored (S360). On the basis of the acquired note data, a phonetic value and a pitch of each music transcription object note are specified (S370, S380).SELECTED DRAWING: Figure 3 |
