This project will enhance the practical experience of the senior undergraduates by providing them with the ability to perform digital signal processing upon extended segments of audio data in the laborator y. Audio data has been chosen because it will permit cost- effective, real time signal processing. The availability of the equipment provided will greatly improve the quality, and quantity, of the experiments that the students can perform. The need to provide an integrated laboratory setup to gather, store, manipulate, and reproduce extended segments of audio data has led to the need to purchase a computer system that has all the pieces from the microphone through the computer to the speaker. The system selected is based upon a NeXT computer, together with some ancillary audio hardware. The system will be used to gather audio data from an experimental setup. The data can either be processed in real time, or stored in the computer and processed off-line. (Processing can be done though both software and the built-in Digital Signal Processing board.) The data can be played back to give the students direct feedback as to what effects the processing had on the audio data.

这一项目将加强联合国的实践经验， 高年级本科生，为他们提供能力， 在扩展的段上执行数字信号处理， 实验室音频数据 y. 选择音频数据是因为它允许成本- 有效的、真实的时间信号处理。 的可用性 所提供的设备将大大提高质量，并且 量，学生可以进行的实验。 需要提供一个综合的实验室设置， 存储、操纵和再现音频扩展段 数据导致需要购买一个计算机系统， 从麦克风到电脑， 扬声器. 所选系统基于NeXT计算机， 以及一些辅助音频硬件。 该系统将用于收集音频数据从一个 实验装置 数据可以在真实的 时间，或存储在计算机中并离线处理。 （处理可以通过软件和内置的 数字信号处理板。数据可以回放 给学生直接的反馈， 音频数据的处理。
