# TarsosDSP: a small JAVA audio processing library

TarsosDSP is a collection of classes to do simple audio processing. It features an implementation of a percussion onset detector and two pitch detection algorithms: Yin and the Mcleod Pitch method.

Its aim is to provide a simple interface to some audio (signal) processing algorithms implemented in JAVA.

To make some of the possibilities clear I coded some examples.

-   "TarsosDSP UtterAsterisk":\[UtterAsterisk.jar\] a game that shows real-time pitch detection with YIN.

-   "TarsosDSP Sound Detector":\[SoundDetector.jar\] is simply to show how to react when (loud) sound is available.

-   "TarsosDSP Percussion Detector":\[PercussionDetector.jar\] is capable of detecting percussion onsets using the method described [here](http://arrow.dit.ie/cgi/viewcontent.cgi?article=1018&context=argcon). It plays a sound from [freesound.org](http://freesound.org) when percussion is detected.

The [source code of TarsosDSP](https://github.com/JorenSix/TarsosDSP) is available on github.

### Presentation at Newline

Saturday the 25th of March TarsosDSP was presented at [Newline](http://0x20.be/Newline/Schedule), a small conference organized by [whitespace](http://0x20.be). Here you can download "the slides I used to present TarsosDSP":\[tarsosDSP_presentation.pdf\], I also created "an introductory text on sound and Java":\[sound_and_java.pdf\].
