| Abstract: | Based on the Fourier analysis method,the system function module of piano timbre recognition and electronic synthesis is designed.As far as timbre recognition is concerned,timbre recognition is the key link of the system.In order to identify the timbre feature matrix,the timbre frequency point is obtained by digital recognition method.Through the system test and analysis,the results show that the piano timbre recognition and electronic synthesis system based on Fourier analysis is in a stable state at the frequency of 600-2100 Hz,and the performance is good;the correct rate of timbre recognition is high,which indicates that the system design perfection is high. |
