Musical Signal Processing Based on Digital Signal Processing Technology

With the rapid development of computer and information, the theory and application of digital signal processing achieved great progress, which was widely applied in audio frequency field, The use of digital signal processing technology made it more flexible and convenient to record and process musical signal. This paper is going to analyze the application of digital signal processing technology in musical signal processing in two aspects: firstly, using digital signal processing time domain technology to add delay and reverberation to the recorded musical signal; secondly, using digital signal processing frequency domain technology to balance the frequency of the recorded musical signal.
