Real-Time Tracking of Simultaneous Musical Inputs Using a Multiprocessor

一位专业音乐家在与其他音乐家一起演奏时，能够听到同时输入的信息，并将这些信息综合起来，以便决定乐谱中的正确位置。这个项目的研究目标是研究允许人工系统模拟这种实时跟踪能力的算法。一个能够与现场音乐家互动演奏并在多处理器上实现的工作计算机表演者将成为测试和开发跟踪算法的工具。由于计算机表演者将需要检查来自多个来源的复杂的音符模式，还需要同时检查乐谱中的几个可能的位置，因此并行处理和模式匹配的考虑将是重要的。这项研究将提供对并行处理和模式匹配方法的洞察；将为音乐家提供一种新的、实用的互动表演工具；并将是多处理器的创新应用。

An expert musician, when playing with other musicians, is able to listen to simultaneous inputs and synthesize that information in order to decide on the correct position in the musical score. The research objective of this project is to investigate algorithms that would allow an artificial system to simulate this real-time tracking ability. A working computer performer, capable of playing intractively with live musicians, and implemented on multiprocessor, will be the vehicle for testing and developing the tracking algorithm. Since the computer performer will need to examine complex patterns of notes from several sources and also to inspect simultaneously several possible locations in the musical score, parallel processing and pattern matching considerations will be important. This research will provide insight into methods of parallel processing and pattern matching; will give musicians a new, practical interactive tool for performance; and will be an innovative application of multiprocessors.
