Abstract: Networked Music Performance (NMP) is envisioned as a potential game changeramong Internet applications: it aims at revolutionizing the traditional conceptof musical interaction by enabling remote musicians to interact and performtogether through a telecommunication network. Ensuring realistic conditions formusic performance, however, constitutes a significant engineering challenge dueto extremely strict requirements in terms of audio quality and, mostimportantly, network delay. To minimize the end-to-end delay experienced by themusicians, typical implementations of NMP applications use un-compressed,bidirectional audio streams and leverage UDP as transport protocol. Beingconnection less and unreliable,audio packets transmitted via UDP which becomelost in transit are not re-transmitted and thus cause glitches in the receiveraudio playout. This article describes a technique for predicting lost packetcontent in real-time using a deep learning approach. The ability of concealingerrors in real time can help mitigate audio impairments caused by packetlosses, thus improving the quality of audio playout in real-world scenarios.
