NaiveFFT class

Performs FFTs (Fast Fourier Transforms) of a particular size.

This implementation can do any size, but is O(n^2), so for large sizes it is much slower. But due to it's simplicity, it's the fastest implementation for small sizes.

Constructors

NaiveFFT(int size)

Constructs an FFT object with the given size.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

size → int

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.

override

Operators

operator ==(Object other) → bool

The equality operator.
