输入一个低频率的正弦波和一个高频的正弦波叠加而成,通过观察频域图和时域图,低频波通过了滤波器,高频大部分被滤除-input of a low-frequency sine wave and a high-frequency sine wave overprinted, By observing frequency domain and time domain map plan, low-frequency waves through the filter, the majority of hig

混响器设计程序，程序部分，与时域与频域的波形图-Reverb design process, part of the program, and the time domain and frequency domain waveform

基于MATLAB对录音进行时域频域分析，并画出直观图，进行傅里叶变换(Based on MATLAB, the recording is analyzed in time domain and frequency domain, and an intuitive diagram is drawn to carry out Fourier transform)
