FftSharp 1.0.7

Published on NuGet on 2020-08-21

• Transform.FftMagnitude() and Transform.FftPower() now return an array of length N/2 + 1 instead of N/2 (#24) Thanks @paradigmn
• Created FftSharp.Transform.RFFT() to return just the real component of a mirrored Complex array
• Created FftSharp.Transform.Absolute() to convert Complex[] to double[]

FftSharp 1.0.6

Published on NuGet on 2020-07-15

• Added helper functions to access FFT frequencies (#22)
• Complex.ToString() now produces better output (#21)
• Added methods for easy Mel scale transformation

FftSharp 1.0.5

Published on NuGet on 2020-06-11

• The Window module now has GetWindowNames() and GetWindowByName() to make it easy to populate a drop-down menu with a list of windows, then generate the window data from that name alone #18
• the ZeroPad() method moved into the Pad module and has additional overloads so it can work on Complex[] and double[] #17
• new FFTmagnitude() method returns normalized FFT magnitude
• FFTpower() arguments are simplified and returned data is now properly normalized
• A FftSharp.Complex mutable datatype was created to replace the immutable Sytem.Numerics.Complex

FftSharp 1.0.4

Published on NuGet on 2020-06-06

• added Window.Rectangular()
• added Window.Cosine()
• created ZeroPad() overload for double[] input

FftSharp 1.0.3

Published on NuGet on 2020-05-27

• The default FFT() method now uses a ~30% faster algorithm. This algorithm is much less expressive in code though, so the original easy-to-read method was renamed and left in the module for reference as a private method.
• Inverse FFT can now be calculated using IFFT()
• Windowing functions now accept an optional normalize argument (useful for convolution)

FftSharp 1.0.2

Published on NuGet on 2020-05-26

• new windowing module makes it easy to window data
• FFT input now must have a length that is a multiple of 2

FftSharp 1.0.1
