LOW DELAY CODEC OPTIMIZED NETWORK MUSIC PERFORMANCE
New York University, 35 West 4th St. Room 303
This demonstration will show musicians playing together remotely, using the Internet as a connection between them. In our demonstration session we will establish a connection between New York University and McGill University and play jazz music as if the musicians were located in the same room. We will show a system that can even be used over home DSL or cable Internet connections.
Having musicians play together over the Internet presents several challenges in terms of low delay audio capture and transmission, time synchronization and bandwidth requirements. One of the main problems for this kind of low delay musical interaction is the network jitter, which leads to audio data packets that arrive too late for playback on the receiving side. Previous approaches used uncompressed audio for transmission. Our new approach is to use compressed audio, with a packet loss resilient version of our Ultra Low Delay audio coder, to accommodate lower bit rate connections and to reduce the network jitter by reducing the load on the network connection. For the network connection the Soundjack software will be used, which can be described as a low latency UDP streaming application.
Event is free to participants and buses will be provided to and from the venue. Seating is limited, however, and tickets will be required. They may be obtained at the AES Tours Desk.
