computers to achieve more processing, input, and output for
music and multimedia performances. The distributed, realtime
object system, Aura, offers a carefully designed
architecture for distributed real-time processing. In contrast
to streaming audio or MIDI-over-LAN systems, Aura offers
a general real-time message system capable of transporting
audio, MIDI, or any other data between objects, regardless
of whether objects are located in the same process or on
different machines. Measurements of audio synthesis and
transmission to another computer demonstrate about 20ms
of latency. Practical experience with protocols, system
timing, scheduling, and synchronization are discussed.
