BigSpeed Voice Chat SDK 3.0 BigSpeed语音聊天SDK的3.0

BigSpeed Voice Chat SDK is a set of two COM controls (Client and Server) that lets you set up a private voice chat network for secure messaging. The transfered data are scrambled using on-the-fly 128-bit AES encryption. BigSpeed语音聊天SDK是一套两张的COM控制（客户端和服务器） ，可以让您建立了一个私人语音聊天网络安全的信息传递方式。移交数据的紧急使用即时的128位AES加密。 The security is provided in two different modes: symmetric encryption with shared secret key and asymmetric encryption with 1024-bit public/private keys. The server is responsible for keeping information on and authentication of online peers. All peers connected to a particular server build a single private community. Fine grained access control is realized by a group of user-oriented permissions. They grant access control privileges to system resources and services in a flexible and secure manner. The voice stream is highly compressed to deliver the best possible sound over a limited-bandwidth connection. In addition, the average bitrate is reduced thanks to the silence compression.安全是两个不同的模式：对称加密与共享密钥和非对称加密与1024位公/私密钥。服务器是负责维持资料和验证的网上同行。所有的同龄人连接到一个特定的服务器建立一个单一的私人社会。细粒度访问控制，实现了一组面向用户的权限。他们给予的特权访问控制系统的资源和服务灵活和安全的方式。流的声音是高度压缩，提供尽可能最好的声音了有限的带宽连接。此外，平均码率降低感谢沉默的压缩。 In the encoder, a voice activity detector with an adjustable trigger level is used to distinguish between regions with normal speech activity and those with silence or background noise. Significant echo suppression is achieved using a robust double talk detector. Capability to mute recording and mute playback is implemented. The incoming and outgoing audio data are available in raw PCM format for visualization in the application. Two special events notify about signal overloading (possible distorsions) and transmission delays (network congestions). Two different kind of text information can be exchanged between peers: alert and chat messages. File transfer capability is implemented for direct file exchange between peers. BigSpeed Voice Chat SDK utilizes an elegant event-driven paradigm for easy integration into Windows applications.A special attention is paid to provide responsive user interface while avoiding multithreading problems. Sample applications are included in Visual Basic 2005 and Delphi 7.在编码，语音活动检测器与可调触发水平是用来区分正常的地区演讲活动和那些沉默或背景噪音。重大回音抑制，实现利用强大的双谈论探测器。能力静音录音和静音回放执行。的传入和传出的音频数据提供原材料的PCM格式的可视化中的应用。两项特别活动通知有关信号超载（可能distorsions ）和传输延迟（网络挤塞） 。两种不同类型的文字信息可以交换同行：警惕和聊天信息。文件传输能力是直接执行档案同行之间的交流。 BigSpeed SDK的语音聊天采用典雅的事件驱动的典范易于集成到Windows applications.A特别注意提供响应的用户界面，同时避免多线程的问题。样品申请列入2005年的Visual Basic和Delphi 7 。
