问题描述

我一直在寻找一个C.执行FFT然而，我不是在寻找一个巨大的图书馆（如FFTW），但一个易于使用的单C-文件实现。不幸的是我一直没能找到这样的事。

I was looking for a FFT implementation in C. However, I am not looking for a huge library (like FFTW) but for a easy to use single C-file implementation. Unfortunately I haven't been able to find anything like this.

有人可以推荐一个简单的实现？

Can someone recommend a simple implementation?

推荐答案

您最好的选择是 KissFFT - 顾名思义这是简单，但它仍然是相当体面快，很多比FFTW更轻巧。这也是免费的，wheras FFTW需要高额许可费，如果你想将其纳入商业产品。

Your best bet is KissFFT - as its name implies it's simple, but it's still quite respectably fast, and a lot more lightweight than FFTW. It's also free, wheras FFTW requires a hefty licence fee if you want to include it in a commercial product.
