samplingRate - samplingRate

Method Detail

analyse

public Object analyse(double[] frame)

Apply this FrameBasedAnalyser to the given data.

Specified by:

analyse in class FrameBasedAnalyser

Parameters:

frame - the data to analyse, which must be of the length prescribed by this FrameBasedAnalyser, i.e. by FrameProvider.getFrameLengthSamples().

Returns:

a double array of the same length as frame

Throws:

IllegalArgumentException - if frame does not have the prescribed length
