Abstract
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 was obtained using one dimension DCT operated on each section.The extreme points of the musical notes were found by comparison with the adjacent sub-sections.And then,the musical scores were got using the principle of least derived notes.The experiments show that this method is very effective.
