This paper will also compare and analyzed the different methods of audio signal extraction and identification of piano keys, to find effective methods to make theoretical preparation for further system development. }, issn = {3080-180X}, doi = {https://doi.org/}, url = {http://global-sci.org/intro/article_detail/jics/22411.html} }
