产生、播放DTMF音频，基于Goertzel算法估计DTMF音频，完成双音多频(DTMF)信号的检测(Generating, playing DTMF tones, DTMF tones based on the estimated Goertzel algorithm to detect the completion of dual tone multi-frequency (DTMF) signal)

基于MATLAB 的语音信号频谱分析与去噪研究 1、通过Matlab读入语音信号，进行频域分析 2、绘制语音信号频谱； 3、设计滤波器并进行滤波； 4、加噪，对比语音信号波形和频谱(Research on speech signal spectrum analysis and denoising based on MATLAB 1, read the voice signal through Matlab and analyze it in frequency domain. 2, draw the frequency spectrum of speech signal; 3. The filter is designed and filtered. 4. Add noise and compare the waveform and spectrum of speech signal)
