Fixed2FFT class

Performs FFTs (Fast Fourier Transforms) of size 2.

This is mainly useful as a base case of CompositeFFT.

Constructors

Fixed2FFT()
Constructs an FFT object.

Properties

Methods

frequency(int index, double samplesPerSecond) → double
Returns the frequency that the given index of FFT output represents.
inherited
indexOfFrequency(double freq, double samplesPerSecond) → double
Returns the index in the FFT output that corresponds to the given frequency. This is the inverse of frequency.
inherited
inPlaceFft(Float64x2List complexArray) → void
In-place FFT.
inherited
inPlaceInverseFft(Float64x2List complexArray) → void
In-place inverse FFT.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
realFft(List<double> reals) → Float64x2List
Real-valued FFT.
inherited
realInverseFft(Float64x2List complexArray) → Float64List
Real-valued inverse FFT.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
