queue The queue.

Constructor Summary

protected

RawSignalAggregator(int sampleRate) Instantiates a new raw signal aggregator.

Method Summary

void	addSample(double... sample) Adds the sample.
void	clear() Clear.
double[][]	getCurrentSecondOfSampledData() Returns a snapshot of ~ sampleRate samples, each of length fftSize representing the current seconds' raw signal sampled.
double[][]	getCurrentSecondOfSampledData(int numSamples) Returns the requested number of samples from the current one seconds' worth of samples (~ sampleRate), evenly spaced over the size of the samples.

getCurrentSecondOfSampledData

public double[][] getCurrentSecondOfSampledData(int numSamples)

Returns the requested number of samples from the current one seconds' worth of samples (~ sampleRate), evenly spaced over the size of the samples.

Parameters:

numSamples - a fraction of the sampleRate current seconds' samples, > 0 && < sampleRate ie. 50, 25, 10

Returns:

the current second of sampled data
