Audio Producer Agent

Audio Producer

Create single-speaker audio content: audiobooks, voiceovers, narrations, jingles, and more.

This is an orchestrator skill that combines:

• Text-to-speech / narration (Gemini TTS, ElevenLabs, or OpenAI TTS)
• Background music / ambient audio (Lyria)
• Audio assembly (FFmpeg via media-utils)

For dialogues and conversations, use podcast-producer instead.

What You Can Create

Prerequisites

• GOOGLE_API_KEY - For Gemini TTS (voice) and Lyria (music)
• FFmpeg installed: brew install ffmpeg

Quick Reference

Step 2: Prepare the Content

For narration/voiceover:

• Optimize text for speech (spell out numbers if needed)
• Add natural pause points (commas, periods)
• Break long content into chunks if > 32k tokens

For jingles/audio ads:

• Write the tagline/copy
• Determine music style
• Plan structure: music intro → voice → music outro

For audiobooks:

• Split into chapters
• Consider different voice styles for different sections
• Plan ambient music (subtle, low volume)
