“…A solution for this problem is decreasing the audio quality or increasing the degree of compression using audio encoders in order to reduce the bit‐rate and correspondingly the required bandwidth. Nevertheless, some applications adopt the peer‐to‐peer model for the audio transmission among the musicians –…”

“…For this reason, video and audio packets are transmitted in order to develop the technique of the student. 45,58,75,76 In these cases, high-quality video is required, but the overall end-to-end delay is higher than 60 milliseconds, which prevents for real-time music performances. In order to create a virtual environment like performing in the same room, some applications adjust the volume of the transmitted audio signal, trying to emulate the direction of arrival for the audio signal like performing in the same environment for each musician.…”

“…Other NMP models use a codec set for improving their quality. For instance, FLAC codec is used for lossless encoding purpose in the work of Gu et al A large number of approaches use ultra–low‐delay encoding methods such as CELT, ULD, or OPUS . A large fraction of the NMP applications use mono/stereo channels and fewer support multiple‐channel configuration.…”

Summary Networked Music Performance (NMP) systems involve musicians located in different places who perform music while staying synchronized via the Internet. The maximum end‐to‐end delay in NMP applications is called Ensemble Performance Threshold (EPT) and should be less than 25 milliseconds. Due to this constraint, NMPs require ultra–low‐delay solutions for audio coding, network transmission, relaying, and decoding, each one a challenging task on its own. There are two directions for study in the related work referring to the NMP systems. From the audio perspective, researchers experiment on low‐delay encoders and transmission patterns, aiming to reduce the processing delay of the audio transmission, but they ignore the network performance. On the other hand, network‐oriented researchers try to reduce the network delay, which contributes to reduced end‐to‐end delay. In our proposed approach, we introduce an integration of dynamic audio and network configuration to satisfy the EPT constraint. The basic idea is that, the major components participating in an NMP system, the application and the network interact during the live music performance. As the network delay increases, the network tries to equalize it by modifying the routing behavior using Software‐Defined Networking principles. If the network delay exceeds a maximum affordable threshold, the network reacts by informing the application to change the audio processing pattern to overcome the delay increase, resulting in below EPT end‐to‐end delay. A full prototype of the proposed system was implemented and extensively evaluated in an emulated environment.

“…This method is implemented by Selecting Forwarding Unit (SFU) [4]- [8]. On the other hand, collecting, mixing and forwarding all audio flows is proposed using another entity called Multipoint Conferencing Unit (MCU) [9], [10]. Additionally, a common trend in NMP projects is that Session Initiation Protocol (SIP) is used to support control messages among transmitter and receiver side.…”

Networked Music Performance (NMP) constitutes a class of ultra-low delay sensitive applications, allowing geographically separate musicians to perform seamlessly as a tele-orchestra. For this application type, the QoS indicator is the mouth-to-ear delay, which should be kept under 25 milliseconds. The mouth-to-ear delay comprises signal processing latency and network delay. We propose a strong collaboration between the network and NMP applications to actively keep the to mouth-to-ear delay minimal, using direct state notifications. Related approaches can be characterized as passive, since they try to estimate the network state indirectly, based on the end application performance. Our solution employs Software Defined Networking (SDN) to implement the network-toapplication collaboration, being facilitated by the well-defined network interface that SDN offers. Emulation results show that the proposed scheme achieves an improvement of up to 59% in mouth-to-ear delay over the existing passive solutions.
