这是一个简单的应用我建立理解波的Windows音频API的基础知识，并获得一个快速傅立叶变换（FFT变换）的基本掌握。它的功能是：双缓冲绘图，取样的音频源，选择一个录音源使用搅拌机，FFT频谱计算阵列，并策划采样数据。 -This is a simple application I built to understand the basics of the Windows Audio WAVE API, and to get a basic grasp on Fast Fourier Tra

录音界面，有时频分析、语音播放、波形文件加载和存储功能。-Recording interface, and sometimes frequency analysis, voice playback, wave file to load and store functions.

实现了DTMF解码，可以解wave中的DTMF可，也可方便移植到ARM下进录音实时解DTMF码，用到各种通讯项目中-Achieve a DTMF decoder, you can wave the DTMF solution can also be easily ported to ARM real-time recording solution into DTMF code, use a variety of communication projects
