Description: G726局域网语音通话程序和源代码
这是使用G726语音压缩(16kbps)和RTP进行传输的程序,因为我没有带WIFI的PPC,所以每个程序都是单独测试的,PC端和PPC端分别都工作正常。
G726编解码算法来自OpenH323.传输使用的RTP可以在RTP程序中找到讲解,这个程序主要是G726的函数。将整个 G726封装为g726_Encode和g726_Decode两个函数,参数为压缩和解压数据存储的地址指针,可以将960字节压缩到120字节和将 120字节解压为960字节。这里G726使用的时候,音频设置为8kHz,16位量化,单声道。
使用方法很简单,只用两端各自输入对方的IP,然后按下“开始对话”,就可以进行语音通信了。
PPC端的运行比较稳定,已经进行了自收自发近一个小时连续工作的测试,非常稳定,话音清晰。-G726 LAN voice calls procedures and the source code is the use of voice compression G726 (16kbps ) and RTP for the transmission process, because I did not bring WIFI the PPC, there are separate procedures for each test, PC - and PPC-were all normal work. G726 codec algorithm from the OpenH323. RTP transmission can be used in the process to find RTP stresses Xie, this procedure is mainly a function of G726. Packaging whole G726 for g726_Encode and g726_Decode two functions, Parameters for the compression and decompression of data storage address pointer, 960 bytes can be compressed to 120 to 120 bytes and bytes to 960 bytes decompression. G726 used here, Audio set to 8kHz, 16 quantify mono. It is very simple to use, with only two ends of the respective input each other's IP, then press

Description: Lakey这是一个免费的CW练习/收/发软件,供大家共同学习研究,有需要源码的朋友可以给我发邮件或加为MSN索取。在未来,我会不断更新其功能和修正错误。之前计划2006年底前拿出的正式版本,由于个人工作和精力等原因,不得已推迟。今天发布的版本,增加了对Koch练习法的支持。但仍然是一个BETA版。
本软件的目标是设计成一个使用简便,能够尽量利用一般PC本身具有的硬件功能和性能(主要指CPU的运算和声卡的音频捕捉/播放能力),实现不用另接特殊外围接口电路,不用改/加装电键等,即可让PC具有摩尔斯电码(Morse Code)的收发能力软件。未来可逐渐通过对PC硬件性能的挖掘,实现对音频信号进行分析、过滤、处理。
这是第一个非正式发行版本,因此很多功能与设计目标还有很大差距。希望大家多提意见!

Description: 银行的数字化监视监控系统是目前比较有市场及应用前景的开发项目,基于不同的MPEG采集卡与硬件外围设备开发的监视监控系统在国内外都有比较成型的技术。为了满足实时监视、实时采集压缩、随时回放、压缩数据流的传播等具体要求,在该系统中使用了一种用于网络视频/音频多点传输(视频广播)的视频数据采集卡,提供AVI(MPEG
I Frame压缩编码)采集、MPG采集。发送端广播MPEG流,接受端接受MPEG流并显示,网络传输采用WinSock 2
IP-Multicast。如果本机为发送端,网络上另外任何一台PC可以作为接收端。只要指定不同端口号,同时可以有多台PC机作为发送端,多台PC机作为接收端接收不同发送端的视频数据,也可在传送数据的同时在本机将数据存为MPEG文件。本文主要介绍在VB的环境下开发MPEG卡采集的Audio/Video数据播放的一些编程技巧。

最新的开发进展,是加入了对wpm值计算的支持,现在Lakey已经可以直接通过设置一个wpm值来设定机器自动发送速度,而不是向过去那样设置复杂的参数。当然,如果你愿意,仍然可以使用过去的方式来设置详细参数,这对一些有特殊要求的人来说比较适合。

-Lakey This is a free CW practice/T/R software for common study and research, there is need to source a friend can give me a message or add to MSN obtain (idirect3d@hotmail.com). In the future, I will continue to update its features and correct mistakes.
The latest development progress, is to add terms of wpm support, and now Lakey has been a wpm directly by setting the value to set the speed of the machine automatically sent, rather than in the past, a complex parameter. Of course, if you wish, you can still use the previous way to set the detailed parameters, which have special requirements for some people is more suitable.
The goal of this software is designed to be an easy to use, to make the best use of general PC itself has a hardware functionality and performance (mainly referring to CPU computing and sound audio capture/playback capabilities) to achieve without the other received a special peripheral interface circuits, do not change/install telegraph key and so

Description: 使用QML仿写了一个PC端微信的界面,具有以下功能:
1.可以显示文本、图片、音频、视频
2.显示的内容根据“发送方”自动左对齐或者右对齐
3.支持全屏查看图片
4.视频可以播放,不过好像需要安装解码器(我装的是LAV Filters)-QML copy of the use of a PC end micro channel interface, with the following functions:
1 can display text, pictures, audio, video
2 shows the content according to the sender automatic left or right aligned
3 support full screen view picture
4 video can be played, but it seems to need to install the decoder (I installed Filters LAV)
