Equalization Filter Algorithm of Music Signal Based on Time-Frequency Domain Analysis

In order to effectively remove the noise existing in the transmission process of music signal, this paper discusses the music signal filtering algorithm from two different angles of time domain and frequency domain, and designs two equalization filters with adjustable parameters. And through the experimental simulation algorithm, the corresponding first-order and second-order low-frequency signal filtering cases are discussed. The effectiveness of the proposed method is demonstrated. At the same time, the method can be generalized to the case of high-order equalization filtering.
