“…In [26] the construction of inaudible pilot signals and associated receiver processing techniques are described, that can be used in audio communication, so that an accurate estimation of the signal's end-to-end delay can be obtained. In this work, the properties of the human auditory system are considered, and the pilot signal is structured so that it is a) acoustically untraceable and b) able to maximize the time accuracy of the delay estimation.…”

Abstract-The MusiNet research project aims to provide a comprehensive architecture and a prototype implementation of a complete Networked Music Performance (NMP) system. In this paper we describe the current status of the project, focusing on critical decisions regarding the system's architecture and specifications, the low delay audio and video coding techniques to be employed, the media relay design, and the synchronous and asynchronous collaboration algorithms to be adopted.
