FFT


Class methods

prepare

Allocates the buffers required for processing.

FFT.prepare(int powerOfTwoSize, int maxNumChannels)



process

Process the given data (either a buffer or a array of buffers.

FFT.process(var dataToProcess)



setEnableInverseFFT

This enables the inverse transform that will reconstruct the signal from the processed FFT.

FFT.setEnableInverseFFT(bool shouldApplyReverseTransformToInput)



setEnableSpectrum2D

Enables the creation of a 2D spectrograph image.

FFT.setEnableSpectrum2D(bool shouldBeEnabled)



setMagnitudeFunction

Sets a function that will be executed with the amplitude information of the FFT bins.

FFT.setMagnitudeFunction(var newMagnitudeFunction, bool convertToDecibels)



setOverlap

Sets an overlap (from 0...1) for the chunks.

FFT.setOverlap(double percentageOfOverlap)



setPhaseFunction

Sets a function that will be executed with the phase information of the FFT bins.

FFT.setPhaseFunction(var newPhaseFunction)



setWindowType

Sets a window function that will be applied to the data chunks before processing.

FFT.setWindowType(int windowType)
