Podcast Generator

Podcast Generator 🎙️

This skill streamlines the creation of audio briefings and podcasts, ensuring clean narration and professional background music mixing.

Workflow

1. Draft Script:

   • Write the script based on the requested topic.
   • Rule: No meta-instructions or bracketed notes (e.g., "[Intro]") in the final script.
   • Persona: Friday (🦞). Sharp, calm, concise.
   • Format: Natural monologue.

2. Generate TTS:

   • Use the tts tool. Always generate as MP3.
   • Save raw voice to: ~/.openclaw/media/temp_voice.mp3.

3. Mix Background Music:

   • Select a track from assets/music/ or find/download CC-licensed ambient techno if a specific vibe is requested.
   • Run the mixer script using paths relative to the skill or user home:

     python3 ./scripts/mix_audio.py \
       ~/.openclaw/media/temp_voice.mp3 \
       ./assets/music/vladislav_zavorin-ambient-techno-405559.mp3 \
       ~/.openclaw/media/output_briefing.mp3 \
       --volume 0.08 \
       --outro-seconds 5
     

   • The background track loops if needed. Once the narration ends, keep the music for five seconds and fade it smoothly to silence. Do not cut it abruptly.

4. Deliver:

   • If an openclaw helper, delivery the final result to the default or specified channel. Otherwise save to the workspace and return the file path.
   • Standard delivery path: ~/.openclaw/media/.

Open Source Music Sources

If specific background tracks are needed, search for and download Creative Commons (CC-BY / CC0) licensed music from:

• Free Music Archive (FMA)
• Pixabay Music (Filtered for "Ambient Techno")
• Wikimedia Commons
• Incompetech (Kevin MacLeod)

Constraints

• Relative Paths: Use relative paths where possible or ~ expansion to avoid hardcoded environment strings.
• Volume: Keep background music at 0.08 for voice clarity.
• Outro: For narration with music, default to a five-second music-only fade-out after the voice ends. Use --outro-seconds to override it when the user requests a different ending.
• Cleanup: Temp files should be overwritten or cleaned up to save space.
