Description: 我在网上转悠了半天，想找一个能实现立体声录音的源代码，最好是能指定声道进行录音（比如：指定录左声道时，右声道的声音就不会被录进来），可我没有找到，只好自己来写一个了。
本程序实现音频文件的播放；单声道录音、立体声录音并保存为.wav文件；
枚举系统中的声卡显示在下拉列表中供用户选择。
指定声道录音的功能我仍然没有实现，若有朋友知道实现方法敬请告知（chrys@163.com）
我的实现方法是：先录制立体声的.wav文件，然后再将声道提取出来，分别保存为
左声道的.wav文件和右声道的.wav文件，方法虽然笨，但也是没办法了。
-I cruise the Internet for a long time and want to achieve a stereo recording of the source code, it would be best to designated channel recording (for example : the designation were left channel, right channel voices will not come to be recorded), I could not find, they themselves had to write one.

Description: 直接压缩成mp3的录音机程序，录音过程中不需要产生.wav文件，边录音边压缩，处理速度快，节约磁盘空间，尤其对长时间录音非常合理。本程序可以录制单声道、立体声、左声道、右声道的语音。录音和播放过程中都有实时的波形显示。特别感谢我的好朋友李志刚的指点，由于他的提醒，我从使用mciSendXXX()改用waveInXXX()。-directly into compressed MP3 recorders procedures, the process of recording have not. Wav file, while recording edge compression, fast processing speed and save disk space, especially for long recording very reasonable. This procedure can record mono, stereo, left channel, right channel voice. Recording and playback process have real-time waveform display. Special thanks to my good friend, Li Zhigang's instructions, he reminded, I use mciSendXXX () switch waveInXXX ().

Description: pcm这段代码首先加载并播放一个声音,然后监听Event.ENTER_FRAME事件,也就是在声音播放时触发onEnterFrame()函数. onEnterFrame()首先调用SoundMixer.computeSpectrum()方法,把波形数据保存在ByteArray对象bytes中.
然后使用矢量绘图API绘制声音的波形.第一个for循环遍历前256个左声道的数据, 并使用Graphics.lineTo()方法从一个点绘到另一个点.第二个for循环遍历接下来的256个右声道的数据,这次以相反的次序绘图,从右到左.最后的波形图可以产生一个有趣的镜像效果.
-pcm this code to load and play the first one voice, and then monitor Event.ENTER_FRAME events, that is, voice playback trigger onEnterFrame () function. onEnterFrame () first call SoundMixer.computeSpectrum () method, the waveform data stored in the ByteArray object in bytes. and then use vector graphics rendering API sound waveform. The first traversal for the cycle 256 before the left channel data, and use Graphics.lineTo () method from one point to another point of painting. The second for the cycle traverse the next 256 right channel data in the opposite order of the drawing, right-to-left. final waveform can produce an interesting image effects.

Description: TBalncer 音频声道均衡控件
基于 DSPack 的音频均衡控件,可以设置左右声道.
因为原版 DSPack 里是没有对左右声道作选择的,要选择左右声道只能通过一边的喇叭出声,另一边没声.
此控件是可以使两个喇叭同时出声.-TBalncer audio channel balanced audio controls DSPack based on balanced control, you can set left and right channels. DSPack years because the original is not on the left and right channels to make the choice, and to choose left and right channels only through the side of the speakers say anything, and the other side did not voice. This control is silent while the two speakers.

Description: 该代码是从SPEEX中提取出来有关回声消息部分的源码
它采取的是在频域进行操作，效果比较好"
经测试，如果原始声音与用于回声消息的参考声音之间存在时钟不同步时，极易发生在回音消息算法中的反溃发散现象.
压缩包中含有测试语音文件：
Input_exsample_stereo.pcm: 8k16bit的线性pcm，含双通道语音。
vleft.pcm: 8k16bit linear pcm, 从Input_exsample_stereo.pcm 中分离出来的左声道音频。
right.pcm: 8k16bit linear pcm, 从Input_exsample_stereo.pcm 中分离出来的右声道音频。
-The code is extracted from the SPEEX news out of the echo part of the source it is taken to operate in the frequency domain, the effect is better " by the test, if the original voice message and a reference for the echo between the voice of the clock is not synchronized easily occurred in the response message algorithm in the phenomenon of anti-ulcer divergence. compressed package file containing the test voice: Input_exsample_stereo.pcm: 8k16bit linear pcm, including dual-channel voice. vleft.pcm: 8k16bit linear pcm, from Input_exsample_stereo.pcm separate the left channel audio. right.pcm: 8k16bit linear pcm, separated from the Input_exsample_stereo.pcm the right-channel audio.

Description: 实时监视
实时监视功能有二种播放方式，直接方式和数据回调方式。直接方式是指通过服务器传送过来的视频数据不需要用户自己去解码就能够显示播放，用户只要调用接口CLIENT_API LONG CLIENT_RealPlay(LONG lLoginID, int nChannelID, HWND hWnd),将窗口句柄传入形参hWnd就能够实时播放视频了；数据回调方式是指服务器传送过来的视频数据通过回调函数由用户自己来处理，如果用户需要播放的话，可以调用解码库dhplay.dll解码播放。
多画面预览方式是指在一个画面上显示多路视频图像。
云台控制
云台控制功能可分为常用控制功能和扩展控制功能。常用控制有云台的上、下、左、右、镜头伸缩、焦距远近、光圈大小等控制。扩展控制功能有预置功能、巡航功能、巡迹功能、线性扫描功能、三维定位、水平旋转等。
-Real-time monitoring functions of two kinds of playback mode, the direct method and the data the way back. Refers to direct them through the server to send the video data does not need to decode the user s own players will be able to display the user interface as long as the call CLIENT_API LONG CLIENT_RealPlay (LONG lLoginID, int nChannelID, HWND hWnd), the window handle hWnd parameter into the the video in real time data callback is referring to the video server to send back data from the user s own callback function to deal with, if the user needs to play, you can call dhplay.dll decoding broadcast decoder library.

Description: 自己用DELPHI编写的音乐播放器，可以实现CD、MP3、WMA格式的音频；另外本播放器还可以显示播放时间、播放进度条调整、左右声道调节、顺序、循环、列表、随机播放等功能，还可以智能搜索本地硬盘上的MP3和WMA格式的文件，导入播放列表就可以播放，而且还可以保存播放列表，有很多的实用功能哦。
-DELPHI prepared with their own music player, can be CD, MP3, WMA audio formats In addition the player can also display time player, the player progress bar to adjust the right and left-channel regulation, order, cycle, list, random play functions can also be intelligent search the local hard drive MP3 and WMA format files, you can import a playlist to play, but also can be saved playlists, there are many practical function Oh.

Description: This document describes a MATLAB implementation of the 3GPP Spatial Channel Model (SCM) [3GPP03]. The accompanying MATLAB code implements the system level channel model described in Section 5 of [3GPP03], except the “far scatterer clusters” feature from Section 5.5.2 and the intercell interference feature from Section 5.7. These features were left out of the implementation because they make certain restricting assumptions about the network layout. The current implementation has no built-in assumptions on network geometry and is hence usable for a variety of simulation purposes.
