sox-12.17.1.tar
- Sox是最为著名的Open Source声音文件格式转换工具。已经被广泛移植到Dos、windows、OS2、Sun、Next、Unix、Linux等多个操作系统平台。Sox项目是由Lance Norskog创立的,后来被众多的开发者逐步完善,现在已经能够支持等多种声音文件格式和声音处理效果。基本上常见的声音格式都能够支持。更加有用的是,Sox能够进行声音滤波、采样频率转换,这对那些从事声讯平台开发或维护的朋友非常有用。当然,Sox里面也包括一些DSP算法,有兴趣的朋友可以下载回去研究。Sox可
faac
- 一种非常好的音频压缩算法,可实现对不同采样率和不同码流的压缩。-a very good audio compression algorithm can be realized on different sampling rates and different bitstream compression.
麦克风录音
- 麦克风录音,可以将录音内容存成wav格式文件。你可以修改wav的采样率和编码-microphone recording, can be recorded as deposit into wav format. You can modify wav sampling rate and coding
获取AVI类型文件的信息
- 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)
