例如,对于1D数据,可以使用`simple_fft_1d`函数进行FFT;对于2D数据,可以使用`simple_fft_2d`函数进行FFT;对于3D数据,可以使用`simple_fft_3d`函数进行FFT。 总之,Simple-FFT Header-only C 库是一个简单、高效且易于使用的FFT实现,适用于需要快速傅里叶变换的场景。

Help with simple FFT problemHi all, Im taking my first steps in FTT processing, and I have a simple doubt that I cant figure out. Im trying a 1.41V sine signal (ie. 1V rms)@1khz and then doing the FFT, i expected to see a 94dBpeak at 1khz but the actual value is incorrect ...
