Abstract
This paper describes the use of Matlab software on the home recording music for the simple Noise Reduction. Matlab is a strong scientific computing and graphics interface software systems. This method can be based on the audio signal of the FFT spectrum analysis and short-term, which included the removal of white noise, a noise elimination reconstruction after the music signal, and through the application of examples prove its effectiveness. The paper introduced the white noise, based on the FFT spectrum analysis and denoising principle, Matlab functions related to the function, and gives the example of a procedure and its results. Experimental results show that the law required the programming simple, the equipment hardware Yaoqiubugao, easy to realize, can quickly in the general Universal completed on PC audio signal in the white noise of Noise Reduction.
