就像一个物理棱镜，它显示光波的频率成分，傅里叶分析可以被认为是一个数学棱镜，可以告诉我们什么谐波或频率成分包含在声波的记录。我们编写了MacScope II程序1，这样用户不仅可以看到谐波幅度图，还可以看到谐波以及这些波如何叠加在一起以重建原始声音曲线。
Much like a physical prism, which displays the frequency components of a light wave, Fourier analysis can be thought of as a mathematical prism that can tell us what harmonics or frequency components are contained in a recording of a sound wave. We wrote the MacScope II program1 so that the user could not only see a plot of the harmonic amplitudes but also see the harmonic waves and how these waves add together to recreate the original sound curve.
