WebRTC音频系统 音频发送和接收
一个完整的音频发送涉及到音频采集、音频增强、混音、音频格式(采样率、声道数)以及编解码和RTP封包以及网络发送环节,在这一过程中WebRTC为了结构上清晰且解耦,对每一层进行了抽象,由于采集端数据是源源不断的,因而数据采集有一个单独的线程实现。 3.1音频数据流发送流程 音频发送流程涉及到的模块如下图所示 图3-1 WebRTC 音频发送数据流 3.2 发送中的编码、RTP打包 webrtc::AudioTransport 更像是个双向桥梁,既支持发送又支持接收,在发送之后还衔接了一个或多个数据流发送模块webrtc::AudioSendStream,其连接了数据采集和发送两端,但是发送端在发送之前还需要对数据降噪、去回声以及编解码和RTP打包,数据的降噪增强就是APM模块实现的,具体APM各个算法处理的细节可见《实时语音处理实践指南》,此小节看 webrtc::AudioSender/webrtc::AudioSendStream 中音频数据编码、RTP 包打包及发送控制的设计和实现。webrtc::AudioSender/webrtc::AudioSendStream...
