这是一个简单的应用，建立了解的Windows音频波形API的基本知识，并得到快速傅立叶变换（FFT）基本掌握。应用程序的特点是：双缓冲图形，采样音频信号源，选择录音源，使用调音台，计算FFT频谱阵列，并绘制采样数据。-This is a simple application built to understand the basics of the Windows Audio WAVE API, and to get a basic grasp on Fast Fourier Transfor

基于MATLAB的简易声音信号频谱分析仪设计源码及设计报告。可以实现音频信号的不同频段滤波。-MATLAB simple voice signal spectrum analyzer design source code and design reports. Can achieve a filtering of the different frequency bands of the audio signal.

通过在VB6环境下编程，实现对音频文件进行扫描、识别和波谱显示。-In VB6 environment through programming, audio files are scanned, identified and spectrum display.
