# Daily Digest Podcast - PRD & Roadmap

## Current State

### ✅ DONE - What's Built & Working
- TTS generation (macOS say - built-in, no external API)
- Audio mixing with ffmpeg (Intro → Speech → Outro)
- Music files in `blog-creator/public/podcast-audio/`
- Environment config set up
- Daily digest workflow at 7am CST
- **TESTED:** Audio generated successfully with music!

---

## What's Left to Do

### 1. Integrate TTS into Daily Digest Cron
- [ ] The 7am cron creates digest but doesn't auto-generate audio
- [ ] Need to add TTS call to the daily-digest workflow

### 2. Refine Audio Mixing (Optional)
- [ ] Current: Simple concat with volume adjustment
- [ ] Could add crossfades for smoother transitions
- [ ] Could add background music bed under speech
