Time domain processing is a basic method of speech analysis.Because the model of piano musical tone is similar to the speech model,the speech time-domain analysis can be used in the analysis of piano musical tone.This paper puts forward a time-domain algorithm of piano pitch recognition based on the frequency characteristics and dynamic window,this algorithm can design more appropriate mode of frame and window according to the detect targets,and also can effectively improve the detection accuracy and speed through the experiments,this method has popularization in the applications of piano tuning and pitch detection of single musical tone.
