~ TarsosDSP Pitch Estimation Synthesizer

The DSP library for Taros, aptly named TarsosDSP, now includes an example showing how to synthesize pitch estimations. The goal of the example is to show which errors are made by different pitch detectors.

To test the application, download and execute the Resynthesizer.jar file and load an audio file. For the moment only 44.1kHz mono wav is allowed. To hear what exactly it does, compare the following two audio fragments:


There is also a command line interface, the following command does pitch tracking, and follows the envelope of in.wav and immediately plays it on the default audio device. If you want to save the audio, see the command line options. The flute example is provided for your convenience.

Name:
	TarsosDSP resynthesizer
----------------------------------------------------
Synopsis:
	java -jar CommandLineResynthesizer.jar [--detector DETECTOR] [--output out.wav] [--combined combined.wav] input.wav
----------------------------------------------------
Description:
	Extracts pitch and loudnes from audio and resynthesises the audio with that information.
	The result is either played back our written in an output file. 
	There is als an option to combine source and synthezized material
	in the left and right channels of a stereo audio file.


	input.wav		a readable wav file.

	--output out.wav		a writable file.

	--combined combined.wav		a writable output file. One channel original, other synthesized.
	--detector DETECTOR	defaults to FFT_YIN or one of these:
				YIN
				MPM
				FFT_YIN
				DYNAMIC_WAVELET
				AMDF


The source code of the Java implementation of the synthesizer can be found on the TarsosDSP github page.
