由于在Windows2000下右键点击RIFF (*.avi,*.wav) 类型的文件，在摘要里没有该文件的具体信息，所以我就编了一个小程序，用来显示该类型文件的信息。具体信息主要包含视频流和音频流信息。视频流信息主要有:(1)Total frames (2)Frame rate (3)Codec (4)视频的宽度和高度等。音频信息主要有:(1)音频的格式 (2)单声道还是立体声 (3)采样频率等。-in Windows2000 Right click RIFF (*. avi,*. wav) file types, in a summary of the document was not specific information, so I compiled a small program used to indicate the type of document information. Specific information mainly includes streaming video and audio streams of information. Video streams of information are : (1) Total frames (2) Frame rate (3) Codec (4) video on the width and height. Major Audio Information : (1) Audio format (2) mono or stereo (3) sampling frequency.

1)编写DFT子函数（计算并画出幅频特性），以后可调用。 2）N=32，M=32，128，256时，分析频率分辨率、频谱的光滑程度。 3）N=64，256，512时，分析频率分辨率和频谱的光滑程度。 -1) the preparation of DFT Functions (calculated and drawn amplitude-frequency characteristics), the future can be called. 2) N = 32, M = 32,128,256, the analysis of the frequency resolution, the degree of smooth spectrum. 3) N = 64,256,512, the analysis of the frequency spectrum resolution and the degree of smoothness.
