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)
