本文介绍一个用于Amiga微型计算机的声音分析与合成程序。用户可以参考时间和幅度参数实时控制信号的捕获。随后，可以编辑和分析所选择的信号。声波图可以在时间和频率上以三种分辨率获得。可以对信号进行时间测量，对声波图进行频率测量，以及对切片进行幅度测量。有三个函数可用于提取基波。合成声音可以通过修改现有声音的幅度和频率调制或通过添加合成来创建新声音来获得。所有的命令都可以用鼠标来选择，程序界面友好。
ABSTRACT This note presents a program for analysis and synthesis of sounds designed to be used with an Amiga micro-computer. The user is in real-time control of the capture of the signal with reference to both time and amplitude parameters. Subsequently the chosen signal can be edited and analysed. Sonograms can be obtained at three resolutions, both in time and frequency. Measurements of time can be made on the signal, of frequency on the sonogram and of amplitude on sections. Three functions for the extraction of the fundamental are available. A synthetic sound may be obtained, either by modifying the amplitude and frequency modulation of an existing sound, or by creating a new sound by additive synthesis. All the commands can be selected by using a mouse, and the program is user-friendly.
