%X Most work about musical score recognition is based on MIDI format file;however,most musical data are stored in audio frequency format.Therefore,this paper discussed a musical score recognition method from WAV format file including solo music signal,adopted the Discrete Cosine Transform(DCT) combined with energy,and presented a principle of least derived notes.The music signal was divided into several sub-sections and the length of each section was equal to the duration of one semiquaver.The base frequency w...
