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:

an array of F0Candidates

Throws:

IllegalArgumentException - if frame does not have the prescribed length

findCandidates

protected abstract void findCandidates(F0Tracker.F0Candidate[] candidates,
                  double[] frame)

normaliseCandidatesScores

protected void normaliseCandidatesScores(F0Tracker.F0Candidate[] candidates)

addCandidate

protected void addCandidate(F0Tracker.F0Candidate[] candidates,
                F0Tracker.F0Candidate newCandidate)
