FFT


Class methods

dumpSpectrum

Dumps the spectrum image to the given file (as PNG image).

FFT.dumpSpectrum(var file, bool output)



getSpectrum2DParameters

Returns the JSON data for the spectrum parameters.

FFT.getSpectrum2DParameters()



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)



setSpectrum2DParameters

Sets the spectrum data from the JSON object.

FFT.setSpectrum2DParameters(var jsonData)



setWindowType

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

FFT.setWindowType(int windowType)
