大速语音聊天 SDK 是一组两个 COM 控件（客户端和服务器），用于 允许您设置一个专用语音聊天网络，用于安全消息传递。 使用飞行 128 位 AES 加密对传输的数据进行爬炒。安全性以两种不同的模式提供：带共享密钥的对称加密和带 1024 位公钥/私钥的不对称加密。 服务器负责保存联机对等体的信息和身份验证。 连接到特定服务器的所有对等体都构建单个私有社区。 细粒度访问控制由一组面向用户的权限实现。 它们以灵活和安全的方式向系统资源和服务授予访问权限。 语音流经过高度压缩，通过有限带宽连接提供最佳声音。 此外，由于静音压缩，平均比特率会降低。在编码器中，具有可调触发级别的语音活动检测器用于区分具有正常语音活动的区域和具有静音或背景噪音的区域。 使用坚固的双对讲检测器实现显著的回声抑制。 实现了静音录制和静音播放功能。 传入和传出音频数据以原始 PCM 格式提供，可在应用程序中进行可视化。 两个特殊事件通知信号过载（可能的丢失）和传输延迟（网络拥塞）。 两者之间可以交换两种不同的文本信息：警报和聊天消息。 文件传输功能用于对等体之间的直接文件交换。 BigSpeed 语音聊天 SDK 采用优雅的事件驱动模式，可轻松集成到 Windows 应用程序中。特别注意提供响应式用户界面，同时避免多线程问题。 示例应用程序包含在可视化基础 2005 和 Delphi 7 中。
