🧮 Processing setup

Environment​

# Navigate to source root directory
cd sound-scape-explorer

# Create virtual environment
python3.10 -m venv venv

# Activate environment
source venv/bin/activate

# Install processing in dev mode
pip install -e processing

# Edit and run code...

Basic user flows​

  1. When user runs sse command, it will trigger the processing.cli:start_processing function
  2. When user selects a menu choice, it will trigger one or more actions from processing.actions
