“…NMP systems aim to render the same conditions as acousticinstrumental on-site performances. An effective remote and distributed music performance entails extremely strict QoS requirements, such as very low communication latency, low and constant jitter (i.e., the variation of latency), and high audio quality (i.e., low packet losses that generate unperceivable dropouts in the signal) [43], [44]. Therefore, audio transfer through a wireless channel must be reliable, fast, and should experience no outages.…”

The availability of high-performance embedded audio systems, along with high-bandwidth and low-latency connectivity options provided by 5G networks, is enabling the Internet of Musical Things (IoMusT) paradigm. A central component of this paradigm is represented by Networked Music Performances (NMPs), where geographically displaced musicians play together over the network in real time. However, to date, IoMusT deployments over 5G networks remain scarce, and very limited statistical results are available on the actual latency and reliability of 5G networks for IoMusT and NMP scenarios. In this paper, we present a private 5G IoMusT deployment and analyze its performance when supporting NMPs. Our IoMusT system is composed of up to four nodes and includes different background traffic conditions. We focused on the assessment of the sole wireless link, as the measurements can be easily transferred to a realistic NMP architecture involving a WAN by compounding them with those of the WAN. Our results show that latency increases with the number of nodes and with the presence of background traffic, whereas the reliability did not vary with the complexity of the conditions. For all tested scenarios, the average measured latency was below 24 ms (including a jitter buffer of 10.66 ms), whereas packet losses occurred with a probability of less than 0.01. However, irregular spikes were found for all latency and reliability metrics, which can significantly reduce the quality of service perceived by the users of NMP applications. Finally, packet loss and latency resulted to be uncorrelated, which suggests that they have different root causes.

“…In such cases, the inevitable delay caused by the physical transit time of network packets is known to affect performance [1,3,6,12]. Therefore, attempts have been made to account for these delays by design or composition [2,4].…”

This paper describes an architecture design process for Networked Music Performance (NMP) platform for medium-sized conducted music ensembles, based on remote rehearsals of Academic Choir of Gdańsk University of Technology. The issues of real-time remote communication, in-person music performance, and NMP are described. Three iterative steps defining and extending the architecture of the NMP platform with additional features to enhance its utility in remote rehearsals are presented. The first iteration uses a regular video conferencing platform, the second iteration uses dedicated NMP devices and tools, and the third iteration adds video transmission and utilizes professional lowlatency audio and video workstations. For each iteration, the platform architecture is defined and deployed with simultaneous usability tests. Its strengths and weaknesses are identified through qualitative and quantitative measurements -statistical analysis shows a significant improvement in rehearsal quality after each iteration. The final optimal architecture is described and concluded with guidelines for creating NMP systems for said music ensembles.

In this article we describe a Networked Music Collective for online live performance events. Four characteristics of live performance (bodies, space and time, musical culture and social process) are identified as the conceptual and technological basis of our approach. Our recent distributed comprovisation, Perripplayear, is used to illustrate these concepts and to describe the technology stack we employed. The Kaon’CPT collective uses diverse instrumentation including acoustic and electronic instruments, voice and digital musical instruments (DMIs). Its members span 12 time zones and their comprovisation is conducted via a custom distributed score.
