FFT - Class in ddf.minim.analysis
FFT stands for Fast Fourier Transform.
FFT(int, float) - Constructor for class ddf.minim.analysis.FFT
Constructs an FFT that will accept sample buffers that are timeSize long and have been recorded with a sample rate of sampleRate.
fileName() - Method in class ddf.minim.AudioMetaData
 
filePath() - Method in interface ddf.minim.spi.SampleRecorder
Returns the full path to the file this is saving to, if it exists.
fillSpectrum() - Method in class ddf.minim.analysis.FourierTransform
 
forward(float[]) - Method in class ddf.minim.analysis.DFT
 
forward(float[]) - Method in class ddf.minim.analysis.FFT
 
forward(float[], float[]) - Method in class ddf.minim.analysis.FFT
Performs a forward transform on the passed buffers.
forward(float[]) - Method in class ddf.minim.analysis.FourierTransform
Performs a forward transform on buffer.
forward(float[], int) - Method in class ddf.minim.analysis.FourierTransform
Performs a forward transform on values in buffer.
forward(AudioBuffer) - Method in class ddf.minim.analysis.FourierTransform
Performs a forward transform on buffer.
forward(AudioBuffer, int) - Method in class ddf.minim.analysis.FourierTransform
Performs a forward transform on buffer.
FourierTransform - Class in ddf.minim.analysis
A Fourier Transform is an algorithm that transforms a signal in the time domain, such as a sample buffer, into a signal in the frequency domain, often called the spectrum.
FREQ_ENERGY - Static variable in class ddf.minim.analysis.BeatDetect
Constant used to request frequency energy tracking mode.
freqToIndex(float) - Method in class ddf.minim.analysis.FourierTransform
Returns the index of the frequency band that contains the requested frequency.
frequency() - Method in class ddf.minim.effects.IIRFilter
Returns the cutoff frequency (in Hz).
frequency() - Method in class ddf.minim.signals.Oscillator
Returns the current frequency.
