Constructor Detail

FrequencyDomainProcessor

public FrequencyDomainProcessor(int fftSize,
                        double amount)

Create a frequencydomainprocessor with the given FFT size.

Parameters:

fftSize - length of the array to be used for the FFT. Must be a power of two.

amount - amount

Throws:

IllegalArgumentException - if fftSize is not a power of two.

FrequencyDomainProcessor

public FrequencyDomainProcessor(int fftSize)

Method Detail

getFFTSize

public int getFFTSize()

applyInline

public void applyInline(double[] data,
               int pos,
               int len)

Apply this frequency domain processor to the given data, and return the processing result in-place.

Specified by:

applyInline in interface InlineDataProcessor

Parameters:

data - the (time-domain) data to process

pos - the position in the data array where the data lies

len - the length of the to-be-processed data

Throws:

IllegalArgumentException - if len is greater than the fftSize of this frequency domain processor.

process

protected void process(double[] real,
           double[] imag)

Here the actual processing of the frequency-domain frame (in cartesian coordinates) happens. This base implementation does nothing.

Parameters:

real - real

imag - imag
