Description: 本文详细讨论了添加到 RTC 的媒体改进特性，这些改进使得最终用户和开发者都能有更愉快的体验。当应用程序被构建在 RTC 客户端 API 之上，最终用户能获得丰富的音视频体验，而开发者可以使程序得到一系列免费的改进。使用这些 API 构建的应用程序还能够访问 RTC 提供的即时消息和出席功能。有关这些API的信息，可在 Windows Platform SDK中获得。
本文讨论了以下的特性和改进之处：
音频视频编解码器的可获得性
回波抵消（AEC）
冗余音频编码
动态抖动缓冲和调整
-discussed in detail in this paper added to the RTC to improve the characteristics of the media, these improvements allow end users and developers will have a more enjoyable experience. When the application has been built on the RTC client API on top, end-users can access the audio-video experience, and the developer can make a series of procedures to improve free. Construction of the use of these API applications can also visit the RTC to provide instant messaging and attend functions. The API information available in the Windows Platform SDK gain. This paper discusses the following features and improvements : the audio and video codec availability echo canceller (AEC) Redundant audio coding dynamic jitter buffer and adjustment

Description: 主要 研 究 用于声音通讯系统中的声回波抵消技术。声回波抵消通常采用声回波抵
消器来实现。具体方法是用自适应滤波器来估计回波信号，并从麦克风信号中减掉该
估计值，从而实现声回波的抵消。回波抵消器中常用的几种自适应滤波算法有LMS,
NLMS, RLS等算法。对现有主要算法的性能进行了分析，并对优缺点进行评价和比
较。为了在收敛速度和运算量之间得到很好的折衷，对NLMS算法改进，得到了
PNLMS算法，对传统的快处理块算法改进，得到了精确块算法。综合两个算法，获
得了一种基于回波路径冲击响应稀疏性和精确块技术的自适应算法(BEPNLMS),
并对该算法作了详细的分析和研究。针对具体应用以及DSP芯片的特点，结合
BEPNLMS算法，给出了一种基于TMS320VC5402 DSP实现回波抵消的软硬件设计
方案。对主要模块电路的设训作了详细介绍，画出了自适应算法和语音检测流程图，
写出了各模块程序的主要部分。最后，对新算法的收敛性和计算复杂度等主要性能作
了验证，说明本算法可行并满足各项指标要求。-err
