Quality Enhancement of Packet Audio with Time-Scale Modification

  title={Quality Enhancement of Packet Audio with Time-Scale Modification},
  author={Fang Liu and JongWon Kim and C.-C. Jay Kuo},
In traditional packet voice or the emerging 2.5G and 3G wireless data services, smooth and timely delivery of audio is an essential requirement in Quality of Service (QoS) provision. It has been shown in our previous work that, by adapting time-scale modification to audio signals, an adaptive play-out algorithm can be designed to minimize packet dropping at the receiver end. By stretching the audio frame duration up and down, the proposed algorithm could adapt quickly to accommodate fluctuating… CONTINUE READING
