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.

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)
