FFT class abstract

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

This is the base class of a bunch of different implementations. Use the FFT.FFT constructor to automatically select the correct implementation for your buffer size.

Implementers

• CompositeFFT
• Fixed2FFT
• Fixed3FFT
• Fixed4FFT
• Fixed5FFT
• NaiveFFT
• PrimeFFT
• Radix2FFT

Constructors

FFT(int size)

Constructs an FFT object with the given size.

factory

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

The size of the FFTs that this object can do.

Methods

frequency(int index, double samplesPerSecond) → double

Returns the frequency that the given index of FFT output represents.

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.

inPlaceFft(Float64x2List complexArray) → void

In-place FFT.

inPlaceInverseFft(Float64x2List complexArray) → void

In-place inverse FFT.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

realFft(List<double> reals) → Float64x2List

Real-valued FFT.

realInverseFft(Float64x2List complexArray) → Float64List

Real-valued inverse FFT.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
