# YIN Pitch Tracker in JAVA

To make [Tarsos](http://0110.be/) more portable I wrote a pitch tracker in pure JAVA using the [YIN algorithm](http://recherche.ircam.fr/equipes/pcm/cheveign/ps/2002_JASA_YIN_proof.pdf) based on the implementation in C of [aubio](http://aubio.org). The implementation also uses some code written by Karl Helgasson and Teun de Lange of the [Jazzperiments project](http://www.jazzperiments.com/jazzperiments.html).

It can be used to perform real time pitch detection or to analyse files. To use it as a real time pitch detector just start the "JAR-file":\[pitch_detector_yin.jar\] by double clicking. To analyse a file execute one of the following. The first results in a list of annotations (text), the second shows the annotations graphically.

\`\`\`ruby\
java -jar pitch_detector_yin.jar flute.novib.mf.C5B5.wav\
java -jar pitch_detector_yin.jar ---file flute.novib.mf.C5B5.wav\
\`\`\`

The provided "flute sample":\[flute.novib.mf.C5B5.wav\] is from [*The Musical Samples* library of the University of Iowa](http://theremin.music.uiowa.edu/MIS.html) and converted to mono wav. The source code of the pitch tracker can be found below.

**Update:** the Yin implementation in Java has been incorporated into the [TarsosDSP project](https://github.com/JorenSix/TarsosDSP). An open source, Real-Time Audio Processing Framework in Java.
