A .NET Standard library for computing the Fast Fourier Transform (FFT) of real or complex data
Get Started
$ dotnet add package FftSharpReadme
FftSharp is a collection of Fast Fourier Transform (FFT) tools for .NET
Quickstart
// Begin with an array containing sample data
double[] signal = FftSharp.SampleData.SampleAudio1();
// Shape the signal using a Hanning window
var window = new FftSharp.Windows.Hanning();
window.ApplyInPlace(signal);
// Calculate the FFT as an array of complex numbers
System.Numerics.Complex[] spectrum = FftSharp.FFT.Forward(signal);
// or get the magnitude (units²) or power (dB) as real numbers
double[] magnitude = FftSharp.FFT.Magnitude(spectrum);
double[] power = FftSharp.FFT.Power(spectrum);
