Murmur utilizes an array of Raspberry Pi modules, with each module connected to 3 microphones, in order to detect open seating in a library space by running a custom sound detection algorithm.

Usage

On server:

1. Run app.py
2. Open the hosted website

On each Raspberry Pi:

1. Run setup.sh to install required dependencies (assuming using Raspian).
2. Configure config.py by updating the UPLOAD_URL to the API endpoint of the server and MIC_RATE and DEV_INDEXES to match the current audio IO devices connected to the Raspberry Pi.

• To run in development, consider using a service like ngrok
• Consider updating MODULE_ID, RECORD_TIME and OUTPUT_FILENAME.

3. Run app.py
