效果比较不错,

注意:他们使用了私有编码方案,一种正弦编码方法。

对ILBC和PLC都有较深入研究。

Demo of Compressed Domain Packet Loss Concealment of Sinusoidally Coded Speech


C. A. Rødbro, M. G. Christensen, S. V. Andersen, and S. H. Jensen

This webpage contains a demo of the speech coder and packet loss concealment (PLC) method that were presented in [1]. The demo consists of three exceprts. In the first, the speech in coded at 8kbps using parametric coding techniques and subsequently decoded with no packet losses. The next excerpt is an example of how the speech may sound if 30% of the packets are lost (randomly) during transmission in a packet-based network such as the Internet. In the last example, 30% are stil lost (same packets as before), but the speech is now synthesized by interpolating the coded parameters in an appropriate way.
