Design and development of networked music performance applications

Networked Music Performance promises to revolutionize music rehearsal and teaching by allowing multiple remote players to simultaneously perform together from different physical locations by means of low-latency audio streaming over telecommunication networks.

However, in order to reproduce realistic rehearsing conditions, multiple technical, psycho-cognitive and purely musical issues must be addressed. In particular, at network level, very strict requirements in terms of latency and jitter must be satisfied to keep the mouth-to-ear transmission delay below a few tens of milliseconds. To this aim, the components of the end-to-end audio chain (local microphone to remote speaker) are being investigated and optimized, considering signal analog/digital conversion, signal codec, signal packetization, signal transmission and hardware real-time-processing limitations.
