My low cost Raspberry Pi based sound localizing ARU is now fully released and ready for use. You can download it from here:
It installs and configures with just one command after downloading and if you had the hardware installs comes up recording.
I've also made a pre-compiled docker image to make sound localizing trival by downloading the image and running it. This docker image make's use of the wonderful opensoundscape library from the Kitzes lab and can also be used as a template for making use of this library with docker.
The project pages contains everything that you need to know to be able to install and use this software, though clearly I will be adding to it continuously.
To give you an idea as to the price. The criticial components are:
* Raspberry Pi Zero W, around 17 euros,
* A compatible GPS can be bought for around 6 euros
* Compatible sound card, around 1 euro
* Cheap microphones below 10 euros can be used though I personally choose to use one based on the primo em272 microphone capsules which are considered top notch by nature recorders but cost around 55 euros pre-built. These are low self noise, high S/N ration, high gain microphones.
With this project I hope to encourage many more geeks to experiment with sound localization and hopefully themselves add to the eco system.
If anyone has any trouble with anything let me know via this website.
