Abstract :
Improved quality of life, more and more people learn playing the piano. However, the piano base frequency will change. Through the method of wavelet noise reduction, useful signal will be separated from noise. By window function, the estimation accuracy of peak estimation method improves and the peak of the signal more clearly show. Matlab simulation result shows it can achieve the goal of measuring piano frequency.
