HARKBird is a set of scripts that allows us to conduct the following processes using HARK and a microphone array with a simple GUI interface:
- HARK has now updated to the version 3.0, which assume the use of python 3.x. However, the current HARKBird use the python 2.7x.
- HARKBird 2.0 includes an interactive classification tool of separated sounds based on t-SNE. See the manual file in the zip file for the detail. Further information will be provided in near future.
- Runs on both Windows and Ubuntu Linux (under the assumption that HARK, HARK-python and other related packages and software are installed correctly).
- records and play a track with a microphone array TAMAGO (System in frontier Inc.). Recording with multiple arrays (connected to a single PC with USB cables) were supported (Ubuntu only).
- performs a preliminary localization (with custom settings of some
- parameters for birdsong recordings)
- outputs the localization results with PDF, JSON, and tab separated text formats for further analyses.
- provides a simple tool for editing and annotating (adding species label) the results.

Note: transfer functions for TAMAGO is not included. Please refer to the website of HARK for further information.

About HARK and HARKBird
- HARK (Honda Research Institute Japan Audition for Robots with Kyoto University) is an open source software for robot audition, which enables us to localize, separate sound sources in real time.
- HARKBird is a set of scripts that use HARK for analyzing acoustic interactions among species and their surrounding acoustic environment.
- HARKBird is developed by the research group of Reiji Suzuki, Graduate School of Information Science, Nagoya University. Currently, it is maintained by Reiji Suzuki and Shinji Sumitani.
- HARKBird is released under the Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0) license (https://creativecommons.org/licenses/by-sa/3.0/).
- Note that HARKBird itself does not contain any packages or files of HARK (only scripts that use HARK).
- We thank the HARK developer team for many supports with regard to construction of the scripts the use of HARK.

An example recording and analysis
- A recording (160513_0_070110_16k001.wav) for about 4 minutes with TAMAGO on May 13th, 2016 at Inabu field, Nagoya University.
- Localized and analyzed by using HARKBird with default settings.
- Then, we roughly labeled species ID using an annotation tool (JBWA: Japanese bush warbler, COTI: Coal tit (COTI_C: calls), BWFL: Blue and white flycatcher, RBLE: Red-billed Leiothrix, OTH: other species / unknown species / other sound sources)
