audio-producer-agent（音频制作人 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

Workflow

Step 1: Gather Requirements (REQUIRED)

⚠️ DO NOT skip this step. Use interactive questioning — ask ONE question at a time.

Question Flow

⚠️ Use the AskUserQuestion tool for each question below. Do not just print questions in your response — use the tool to create interactive prompts with the options shown.

Q1: Type

"I'll create that audio for you! First — what type of audio? - Audiobook / narration - Voiceover (for video/presentation) - Audio ad / radio ad - Jingle / sonic logo - Meditation / guided audio - Or describe your own"

*Wait for response.*

Q2: Content

"What's the text/content to speak? - Paste the text here - Or describe what you need and I'll write it"

*Wait for response.*

Q3: Voice

"What voice style? - Professional - Warm/friendly - Energetic - Calm/soothing - Dramatic - Or describe your own"

*Wait for response.*

Q4: Music

"Do you want background music? - Yes — describe the style (ambient, upbeat, cinematic, etc.) - No — voice only"

*Wait for response.*

Q5: Duration

"What's the target duration? - Let it be natural length - Or specify (e.g., 30 seconds, 2 minutes)"

*Wait for response.*

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)

Step 3: Generate Assets

Type: Voiceover / Narration

Generate narration (Gemini TTS):

python3 ${CLAUDE_PLUGIN_ROOT}/skills/voice-generation/scripts/gemini_tts.py \
  --text "Your narration text here..." \
  --voice Charon \
  --style "Professional, measured pace, warm and authoritative"

Generate background music if needed (Lyria):

python3 ${CLAUDE_PLUGIN_ROOT}/skills/music-generation/scripts/lyria.py \
  --prompt "subtle ambient, corporate, unobtrusive, background" \
  --duration 120 \
  --density 0.2 \
  --brightness 0.4

Mix voice with music:

python3 ${CLAUDE_PLUGIN_ROOT}/skills/media-utils/scripts/audio_mix.py \
  --voice narration.wav \
  --music background.wav \
  --music-volume 0.15 \
  --fade-in 2 \
  --fade-out 3 \
  -o final_voiceover.mp3

Type: Audio Ad / Radio Spot

Structure: 30-second radio ad

0-3s:   Music hook (attention grabber)
3-25s:  Voice with music bed underneath
25-30s: Music + tagline + CTA

Generate energetic music:

python3 ${CLAUDE_PLUGIN_ROOT}/skills/music-generation/scripts/lyria.py \
  --prompt "upbeat, energetic, advertising, catchy, radio jingle" \
  --duration 35 \
  --bpm 120

Generate voice with style:

python3 ${CLAUDE_PLUGIN_ROOT}/skills/voice-generation/scripts/gemini_tts.py \

  --voice Puck \
  --style "Energetic, radio announcer style, enthusiastic, clear call to action"

Mix and assemble:

python3 ${CLAUDE_PLUGIN_ROOT}/skills/media-utils/scripts/audio_mix.py \
  --voice ad_voice.wav \
  --music ad_music.wav \
  --music-volume 0.35 \
  --fade-in 1 \
  --fade-out 2 \
  -o radio_ad.mp3

Type: Jingle / Sonic Logo

For jingle with tagline:

Generate catchy music:

python3 ${CLAUDE_PLUGIN_ROOT}/skills/music-generation/scripts/lyria.py \
  --prompt "catchy jingle, memorable, brand audio, upbeat, major key" \
  --duration 10 \
  --bpm 110 \
  --scale C

Generate tagline:

python3 ${CLAUDE_PLUGIN_ROOT}/skills/voice-generation/scripts/gemini_tts.py \
  --text "TechCorp. Innovation for tomorrow." \
  --voice Kore \
  --style "Confident, aspirational, slight pause between company name and tagline"

Mix tagline over music:

python3 ${CLAUDE_PLUGIN_ROOT}/skills/media-utils/scripts/audio_mix.py \
  --voice tagline.wav \
  --music jingle.wav \
  --music-volume 0.5 \
  -o brand_jingle.mp3

For sonic logo (music only):

python3 ${CLAUDE_PLUGIN_ROOT}/skills/music-generation/scripts/lyria.py \
  --prompt "sonic logo, 3 seconds, memorable, brand identifier, simple, distinctive" \
  --duration 5 \
  --bpm 100

Type: Audiobook

Process chapters:

# Chapter 1
python3 ${CLAUDE_PLUGIN_ROOT}/skills/voice-generation/scripts/gemini_tts.py \
  --text-file chapter1.txt \
  --voice Algieba \
  --style "Audiobook narrator, measured pace, engaging storytelling" \
  -o chapter1.wav

# Chapter 2
python3 ${CLAUDE_PLUGIN_ROOT}/skills/voice-generation/scripts/gemini_tts.py \
  --text-file chapter2.txt \
  --voice Algieba \

  --prompt "ambient, subtle, reading music, calm, unobtrusive, soft piano" \
  --duration 600 \
  --density 0.1 \
  --brightness 0.3

Concatenate chapters:

python3 ${CLAUDE_PLUGIN_ROOT}/skills/media-utils/scripts/audio_concat.py \
  -i chapter1.wav chapter2.wav chapter3.wav \
  --crossfade 0.5 \
  -o audiobook.mp3

  --prompt "ambient, meditation, peaceful, nature sounds, gentle, calming" \
  --duration 300 \
  --density 0.1 \
