1.录制一段自己的语音信号,对录制的信号进行采样 画出采样后语音信号的时域波形和频谱图 给定滤波器的性能指标,采matlab设计数字滤波器,并画出滤波器的频率响应 然后用自己设计的滤波器对采集的信号进行滤波,画出滤波后信号的时域波形和频谱,并对滤波前后的信号进行对比,分析信号的变化 回放语音信号。2.-1. Recorded his voice for some signal, the signal is sampled on the record draw sampled speech si

数字信号处理的课程设计，用matlab对给定音频信号进行处理。-Course design of digital signal processing using MATLAB to process the audio signal is given.

This a one-credit lab supplementing the three-credit junior-level DSP course 332:346 Digital Signal Processing . It consists of four hardware labs using the Texas Instruments TMS320C6713 DSP Starter Kit, and two MATLAB software labs. Lab begins

Implementation of convolution in matlab for audio procesing

利用matlab将自己的录好的音频加入噪声后，在利用滤波器滤除噪声，回复原始音频(After using MATLAB to add its recorded audio to noise, the filter is used to filter the noise and restore the original audio.)
