摘要： An audio signal processing system including an input circuit for inputting musical instrument digital interface (MIDI) commands in real time over a plurality of channels, a computer including a central processing unit (CPU) supplied with the MIDI commands for simultaneously synthesizing one or more voices for each of the channels in response to the MIDI commands, each of the voices being generated by one or more of a plurality of predefined audio synthesis algorithms executed in software, a random access memory (RAM) for storing digital voice data representative of each of the voices generated by the CPU, an output circuit for audibly reproducing the voices from the digital voice data stored in the RAM, and wherein the CPU, in generating the voices selects the one or more audio synthesis algorithms based on one or more of the following criteria: the external processing demands placed upon the CPU by other operations being performed by the personal computer, a best match, according to predetermined criteria, between the type of voice required and audio synthesis algorithms available to the CPU, and the availability of wavetable voice data to be buffered into the RAM.

摘要： An Internet high fidelity audio transmission and compression protocol including a system for representing synthesized music in a relatively small file as compared to digital recording. The protocol includes a method for streaming the transmission of a music data file from a Server-Composer computer such that the music can begin being played back as soon as the file begins to arrive at a Client-Player computer. The system includes a graduated resolution improvement feature which allows the music to be recreated exactly as originally composed as the necessary wavetable data is downloading in the background and the music continues to play in the foreground.
摘要翻译：一种互联网高保真音频传输和压缩协议，包括与数字记录相比在相对小的文件中表示合成音乐的系统。该协议包括用于从服务器 - 作曲家计算机流式传输音乐数据文件的方法，使得一旦文件开始到达客户端 - 播放器计算机就可开始播放音乐。该系统包括分级分辨率改进功能，其允许按照最初的组合重新创建音乐，因为必要的波表数据正在背景中下载并且音乐在前景中继续播放。
