VC++下的录音程序,可以设定采样频率和采样精度,录音完毕后自动生成WAVE文件.

对原始语音进行上采样和下采样，分析对比他们的时域图和频谱图。最后对比原始语音、75HZ激励、150HZ激励以及噪声激励下的效果-SOME SIMPLE MANIPULATIONS OF SOUND USING DIGITAL SIGNAL PROCESSING The original sound and its spectrogram Downsampling the waveform downsampling Upsampling the waveform Li

linux下录音编码和解码播放，两个进程，一个负责采样编码，一个负责解码播放，两进程通过管道通信。-under linux recording encoding and decoding playback, the two processes, one is responsible for sampling encoding one responsible for decoding the play, the two processes by pipe communication.

VS2010环境下C++编写，用于读取wav文件，分析文件头，显示通道数目、采样率、比特率、文件长度、量化位数等信息。-VS2010 environment C++ prepare for reading wav files, analyze the file header, showing the number of channels, sample rate, bit rate, file size, number of quantization bits and other informa
