Conceptos Básicos
A networked music performance system called MEVO enabled a distributed concert between musicians in Turin, Italy and Wrocław, Poland, demonstrating the feasibility of real-time remote musical collaboration.
Resumen
The paper presents an example of a Networked Music Performance (NMP) system called MEVO, which was used to facilitate a distributed concert between musicians in Turin, Italy and Wrocław, Poland in June 2023.
Key highlights:
MEVO is an NMP system under development at Politecnico di Torino, designed to support remote music education and accessibility for users with visual, auditory, and mobility impairments.
The distributed concert featured 3 musicians in Turin and 3 musicians in Wrocław, performing 5 pieces composed specifically for the event.
The system was able to maintain a stable end-to-end audio latency, with 99.986% of round-trip times being less than 59ms.
While some packet losses were observed, leading to audible gaps, the overall feedback from musicians and the audience was that the system was transparent enough to have a negligible impact on the perceived quality of the performance.
The experiment highlighted the need for further improvements, such as the integration of packet loss concealment techniques and refinement of the audio buffer dynamic estimation.
Estadísticas
The minimum measured round-trip time (RTT) value was 51.985 ms at one side and 52.011 ms at the other.
99.986% of the measured RTTs was < 59ms at both sides.
The ratio of lost frames was 0.131% at the Wrocław side and 0.177% at the Turin side.
The overall mouth-to-ear latency experienced by the musicians was within [32, 61]ms.
Citas
"Even though the development of MEVO is in its early stage, the overall feedback received from the musicians and the audience was that the system is already stable and transparent enough to introduce negligible impact on the perceived quality of experience."
