AC3编解码器的设计与实现的标准（中文版）

对于pcm_s16le波形进行增益 可对以下参数进行调节： amplitude_threshold 声音波形幅值的阈值，默认为0 sub_frane_limit 子帧数限制，子帧数内的波形被作为整体对待，统一进行放大缩小，默认为0.5秒采样数 headroom dbfs净空高度 默认为-6.18dbfs max_gain 最大增益，单位分贝，默认为20 noise_floor 噪音阈值，dbfs，默认为-40  

就是按输入的时间录音，回放，显示波形及频谱图 录音过程中有动态频谱显示 -Itis input by the time recording, playback, show the waveform and frequency spectrum of dynamic recording process of the spectrum shows

C++编译OpenH323代码的源代码，有助于学习掌握基本的OpenH323技术。值得学习和参考-C++ Compile OpenH323 code, source code, contribute to learning and mastering the basic techniques of OpenH323. Worthy of study and reference

外国聊天工具,有服务器.B-S结构,不错还有二纬动画!设计-foreign chatting tool, a server. B-S structure, it is true there are two weft animation! Design

利用JMF(Java Media Framework,java多媒体框架)，以JBuilder9为开发工具进行开发的视频播放系统，是学习JMF、JBuilder以及java编程中panel、"容器"等概念的一个优秀例子-using JMF (Java Media Framework, java Multimedia Framework), JBuilder9 development tools for the development of video playback system, is learning JMF, JBuilder and java programming panel, "containers" such as the concept of an outstanding example

快速傅里叶变换算法的c语言实现程序，具体描述了fft算法的实现过程-Fast Fourier Transform algorithm c language implementation procedures, specific description of the fft algorithm implementation process

Opus is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet, but is also intended for storage and streaming applications. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype"s SILK codec and Xiph.Org"s CELT codec.

自己编写的一款可以进行双路PCM语音混频的程序，针对的是16位的PCM语音数据，经过验证，比常规的混音算法质量好许多，特别是进行多路混频时，重复调用该程序也可以达到比较满意的结果。-own section can be prepared for two-way voice PCM mixing procedures, The address is 16 PCM voice data, after verification, than conventional mixing algorithm many good quality, especially for multi-channel mixer, repeat the procedure call also will be more satisfied with the results.

文件功能：计算染噪正弦信号的小波变换，其中的连续小波变换，尺度a的值越大，相当于傅里叶变换中w值越小。用到了产生均值为0，方差为1的高斯随机序列，白噪声序列
