Network-centric Music Performance (NMP) enables Internet-based multiparty music performance through cyberspace. Our goal is to support real-time distributed natural audio delivery over the network, using audio compression schemes with exceptional audio quality. Among many challenges, a tight delay bound between the production and perception of the audio is a dominant requirement. The demo video shows a recorded session of a live network-centric music performance demonstration involving a SDSL access network. It demonstrates that musicians can play together smoothly on a virtual stage provided by NMP. Beyond our previous work of realizing NMP in local and wide area research networks, this is the first time NMP has been enabled with a commercially available synchronous DSL access network. The positive ratings by the musicians confirm that NMP is ready for large-scale commercial deployment once such access technology is widely available and affordable to the end users.
