rtrytvbi
- iLBC 产生背景 在VoIP的应用中,大部分厂商采用CELP (Code Excited Linear Prediction) 算法的低速率语音编解码,如ITU G.729和G.723.1等。而VoIP应用主要在包交换的IP网络上进行传输,无法避免IP网络的丢包、延时、抖动等实时传输问题,而传统的这几个CELP算法对高丢包的处理不是很好,因而很大程度上会影响语音通话效果。 -iLBC background in the application of VoIP, Most manu

An_Adaptive_Jitter_Buffering_Algorithm_for_Voice_o
- 当IP语音包的网络时延抖动较小时,一般的语音缓冲算法可以得到较好的语音质量。当网络中存在突发大时延时,就会出现极大丢包率或极大端到端时延,从而难以获得好的语音质量。为此,提出针对突发大时延下的自适应语音缓冲算法。通过估算网络平均时延和学习语音包经过的网络路径上的状态,来确定需要控制端到端时延大小和语音包的丢包率,动态调整Jitter Buffer队列的最小深度和最大深度,从而可以尽量减小语音裂缝(gap)的出现。通过基于听觉模型的客观音质评价(PESQ)仿真计算以及在实际语音网关设备中的应用表明

Phone
- 网络多媒体通信 1、编制一个网络多媒通信软件,实现: 在发送端采集话筒声音,通过网络实时传输到接收端,并在接收端播放出来。 2、通过使用TCP、UDP、变更分组大小来对比收发端声音同步情况及播放质量。 本实验技术不同于课上所讲的回调函数,利用了MFC的消息处理机制,用消息处理函数替代了回调函数,但整个流程是一样的。本程序采用C/S模式,其中Server端为项目PhoneToFile,Client端为项目Client,Server端的功能为采集声音数据并发送给客户端,Client
