Audio Pipeline Overview

Automated audio generation for Elmar's morning drive — CEO briefing, radio show, social pulse. All pieces register with the audio-library so they surface on MC's /briefings page.

Components

CEO Audio Briefing

• Source: reads generated Dashboard.html (built by ceo-dashboard-build at 08:30 SAST — see 08-projects/overview)
• Narrative: Claude generates a short narrative script from the dashboard numbers, focused on what moved vs yesterday
• TTS: ElevenLabs voice cloning for a natural-sounding delivery
• Output: .mp3 in ~/workspace/reports/audio/ceo-briefing-YYYYMMDD.mp3, registered in audio-library

Radio Show System

• Daily (radio-daily-brief): news brief across priority-1 interests (aviation, SA macro, geopolitics, crypto, AI). Seed sources → NotebookLM audio overview.
• Weekly (radio-weekly-episode): longer deep-dive episode, Deep Research enrichment before NotebookLM.
• Skill: 07-skills/key-skills|radio-show drives the pipeline end-to-end.

Social Pulse

• Goal: capture what's trending today across Elmar's interest topics without requiring him to open Reddit/X/YouTube
• Sources: Reddit (sort=hot, see MC-625 48h freshness fix), X via ScrapeCreators, YouTube Search API
• Output: ~10-minute NotebookLM audio overview
• Guardrail: enforces 48h freshness filter (MC-625) to prevent 2021-era content from leaking in

Audio Library

All generated audio is registered in the audio-library table so MC's /briefings page can surface it with metadata:

• type — ceo | radio-daily | radio-weekly | social-pulse
• date — generation date
• duration_s — audio length
• mp3_path — local file path served by MC

MC /briefings Page

Single page on Mission Control listing the last 14 days of briefings by type. Elmar opens this to catch up on anything he missed. Any new audio producer must register with the audio-library to show up here (registering in audio-library is not automatic — each producer calls it explicitly after rendering).

Failure Modes

• ElevenLabs rate limit — CEO briefing falls back to silent skip + Telegram alert
• NotebookLM login expiry — daily/weekly radio use the noVNC auth portal (MC-532) to re-auth on a cadence
• Dashboard missing — CEO audio briefing requires Dashboard.html from ceo-dashboard-build; if that failed, audio briefing sends a Telegram notice instead of producing empty audio

• 08-projects/overview — CEO dashboard project (data source)
• 04-notifications/overview — Telegram forum where briefings land

Key Takeaways

• Four audio producers run on schedule: CEO briefing, daily radio, weekly deep episode, social pulse
• All outputs register with the audio-library so the MC /briefings page surfaces them
• Producers pull from distinct source stacks (Dashboard.html, NotebookLM, Reddit/X/YouTube) but converge on the same delivery surfaces (MC + Telegram)
• CEO briefing is blocked by ceo-dashboard-build — failure there cascades here
