Samsung Innovation Campus: Final Project
Source Code File w/o Sound Source Localization Function

This project aims to gather and classify the traffic sounds with Raspberry Pi, and later display them visually from a mobile app to the driver with hearing loss. I hope this will be beneficial for future work for providing safe driving for everyone.

Yarasa - Android.zip is to-be-created .apk file may be installed on an Android device.

Contents of Yarasa - Pi should be placed on a directory of your choice on your Raspberry Pi.

These project elements are yet to be set for an automatic connection. Following steps shall be followed for a smooth operation.

You need a Raspberry Pi 3+, a ReSpeaker 4-Mic Array for Raspberry Pi, and an Android smartphone for this system.

Firstly, your Raspberry needs to know how to operate a ReSpeaker. Simply follow the instructions on ReSpeaker Wiki.
Hint: This process might be a little challenging, but remember that instead of using "sudo ./install.sh", using the following can save your life:
sudo ./install.sh --compat-kernel
Not my favorite solution, but gets things done.

On your Raspberry Pi, you should follow the instructions given on Yurockkk's Repistory to obtain a successful Bluetooth connection between Android & Raspberry Pi. Shout-out to them for the help of their project for establishing the Bluetooth connection between these parts.

Simply run Yarasa-Pi.py on your Raspberry Pi. If this is your first time running such a program on your Pi, you might struggle with libraries for some time, thanks to the limited resources of the Rasbian environment.

The Android device that has the Yarasa - Android.rar on it should be connected to your Pi via Bluetooth.

And that should do it. This project is a very basic first step, and certainly open for improvements, especially for sound source localization. Together we can build an equally safe, easy, and enjoyable living for everyone.
