一段时间以来，傅里叶变换一直是时域和频域之间的桥梁。现在可以在波形和频谱之间来回切换，速度和经济都足够快，可以为这个经典的数学设备创造一个全新的应用范围。本文旨在作为快速傅里叶变换的入门，它已经彻底改变了波形的数字处理。读者的注意力特别集中在1969年6月的IEEE音频与电声学学报上，这是一个专门讨论快速傅里叶变换的特刊。
For some time the Fourier transform has served as a bridge between the time domain and the frequency domain. It is now possible to go back and forth between waveform and spectrum with enough speed and economy to create a whole new range of applications for this classic mathematical device. This article is intended as a primer on the fast Fourier transform, which has revolutionized the digital processing of waveforms. The reader's attention is especially directed to the IEEE Transactions on Audio and Electroacoustics for June 1969, a special issue devoted to the fast Fourier transform.
