Welcome to AviaNZ, an open-source project for manual and automatic analysis of bio-acoustic recordings.

---

This software enables you to:

• review and listen to wav files from acoustic field recorders,
• segment and annotate the recordings,
• train filters to recognise calls from particular species,
• use filters that others have provided to batch process many files
• review annotations
• produce output in spreadsheet form, or as files ready for further statistical analyses

For more information about the project, see http://www.avianz.net

Installation

Windows

Windows binaries are available at http://www.avianz.net. To install from source, follow the Linux instructions.

macOS

An installer script is available at http://www.avianz.net. To install from source, follow the Linux instructions.

Linux

No binaries are available. Install from the source as follows:

1. Download the source .zip of the latest release.
2. Extract (unzip v2.0.zip) and navigate to the extracted directory.
3. Ensure Python (3.6 or higher), pip and git are available on your system. On Ubuntu, these can be installed by running:

sudo apt-get install python3.6
sudo apt-get install python3-pip
sudo apt-get install git

4. Install the required packages by running pip3 install -r requirements.txt --user at the command line. (On Ubuntu and some other systems, python and pip refer to the Python 2 versions. If you are sure these refer to version 3 of the language, use python and pip in steps 4-6.)
5. Build the Cython extensions by running cd ext; python3 setup.py build_ext -i; cd..
6. Done! Launch the software with python3 AviaNZ.py
