Class PitchResyntheziser

java.lang.Object

be.tarsos.dsp.synthesis.PitchResyntheziser

All Implemented Interfaces:

PitchDetectionHandler

public class PitchResyntheziser
extends java.lang.Object
implements PitchDetectionHandler

This pitch detection handler replaces the audio buffer in the pipeline with a synthesized wave. It either follows the envelope of the original signal or not. Use it wisely. The following demonstrates how it can be used.

 
 PitchEstimationAlgorithm algo = PitchEstimationAlgorithm.FFT_YIN;
 PitchResyntheziser prs = new PitchResyntheziser(samplerate);
 AudioDispatcher dispatcher = AudioDispatcher.fromFile(new File("in.wav"),1024, 0);
 //Handle pitch detection
 dispatcher.addAudioProcessor(new PitchProcessor(algo, samplerate, size, prs));
 //Write the synthesized pitch to an output file.
 dispatcher.addAudioProcessor(new WaveformWriter(format, "out.wav"));//
 dispatcher.run();
