Metadata Generation

Generate a structured JSON file containing metadata for the radio show. This is done by sending the final mixed audio file and the original transcript back to Gemini.

Prerequisites

pip install google-genai

Workflow

1. Read Inputs: Load the transcript from ./workspace/data/script.md and the final audio from ./workspace/audio/final/ai_radio.mp3.
2. Upload Audio: Upload the audio file to the Gemini Files API.
3. Generate Metadata: Call Gemini (e.g., gemini-3-flash-preview) using the Interactions API, passing the uploaded audio file and the transcript.
4. Save Output: Save the resulting JSON to ./workspace/data/show_notes.json.
