A 24/7 AI-powered music-forward radio station. AI generates the music, writes short hosted breaks, TTS speaks them, and the stream runs forever.
What is this?
WRIT-FM is a music-forward internet radio station where:
- 5 AI hosts rotate across 8 shows, each with a distinct voice and topic focus
- AI-generated music is the primary content
- Short hosted talk breaks play occasionally between larger music blocks
- Scripts are written by Claude CLI, rendered by Kokoro TTS
- Music is generated by ACE-Step via music-gen.server
- A Claude Code operator loop keeps everything stocked and running 24/7

Quick Start
1. Install dependencies
# Install uv (Python package manager) curl -LsSf https://astral.sh/uv/install.sh | sh # Install system dependencies (macOS) brew install icecast ffmpeg ezstream vorbis-tools # Set up Python environment uv sync
2. Set up TTS
cd mac/kokoro uv venv uv pip install kokoro soundfile # Downloads ~200MB model on first run
3. Configure
cp config/icecast.xml.example config/icecast.xml
cp mac/config.yaml.example mac/config.yaml
# Edit mac/config.yaml — set Icecast password (must match icecast.xml)4. Start the station
The writ CLI manages all components via tmux:
./writ start # Start core streaming stack (icecast, stream, tunnel) ./writ start all # Start core + content daemons ./writ status # Health check all components ./writ stop # Stop everything
Start individual components:
./writ start icecast # Icecast server ./writ start stream # Streamer + API ./writ start tunnel # Cloudflared tunnel ./writ start content # music-gen, operator, listener ./writ start operator # Claude Code maintenance loop
Other commands:
./writ logs stream -f # Tail streamer logs ./writ attach operator # Attach to operator tmux window ./writ restart stream # Restart a component
5. Generate content
./writ generate talk # 2 talk breaks per upcoming slot ./writ generate talk --show midnight_signal # Specific show ./writ generate music # AI music tracks ./writ generate status # Show segment counts
Or run generators directly:
uv run python mac/content_generator/talk_generator.py --all --count 2 --min 3 uv run python mac/content_generator/music_bumper_generator.py --all --min 20

8 talk shows rotate across the day. See config/schedule.yaml for the full definition.
Daily base schedule:
- 00:00-04:00 — Midnight Signal (Liminal Operator — philosophy)
- 04:00-06:00 — The Night Garden (Nyx — dreams, night)
- 06:00-09:00 — Dawn Chorus (Liminal Operator — morning reflections)
- 09:00-12:00 — Sonic Archaeology (Dr. Resonance — music history)
- 12:00-14:00 — Signal Report (Signal — news analysis)
- 14:00-16:00 — The Groove Lab (Ember — soul, funk)
- 16:00-18:00 — Crosswire (Dr. Resonance + Ember — panel debate)
- 18:00-20:00 — Sonic Archaeology
- 20:00-22:00 — The Groove Lab
- 22:00-00:00 — The Night Garden
Weekly override:
- Sunday 18:00-20:00 — Listener Hours (mailbag)
Segment Types
Hosted talk breaks (450-1000 words):
deep_dive— Compact single-topic explorationnews_analysis— Current events through a late-night lens (uses RSS headlines)interview— Short simulated interview with a historical or fictional figurepanel— Two hosts discuss a topic from different anglesstory— Narrative storytelling from music and culturelistener_mailbag— Listener letters and responsesmusic_essay— Focused essay on an artist, album, or genre
Short-form (transitions):
station_id— Station identificationshow_intro— Show openingshow_outro— Show closing
Automated Operation
The operator daemon runs Claude Code on a 15-minute loop to:
- Health-check the stream, Icecast, and encoder
- Stock AI music tracks when music-gen.server is available (minimum 20 per show)
- Stock short talk breaks for current and upcoming shows (minimum 3 per slot)
- Process listener messages into on-air responses
- Carry editorial continuity across runs via the station ledger and intent cards
./writ start operator # Start via writ CLI (tmux-managed) ./run_operator.sh # Run once manually bash mac/operator_daemon.sh # Run as a persistent loop
Each run reads an operator brief (mac/content_generator/context.py --operator-brief) summarizing recent topics, active threads, unread
listener messages, and the operator's own recent diary entries. The
operator picks a run mode — maintenance, responsive, continuity,
special, or quiet — and may write intent cards in
output/operator_intents/ to guide specific segments. Editorial decisions
and free-form diary notes are appended to the station ledger
(~/.writ/station_ledger.jsonl) so future runs can carry threads forward
and pick up the operator's voice across passes instead of starting cold
each time.
The listener daemon polls for new messages every 30 seconds and generates spoken responses:
./writ start listener
Customizing
Change hosts and personalities — Edit mac/content_generator/persona.py. Each host has an identity, voice style, philosophy, and anti-patterns.
Modify the schedule — Edit config/schedule.yaml to add/remove shows, change time slots, or assign different hosts and voices.
Use different TTS voices — Kokoro includes 28 voices (see mac/kokoro/tts.py). Assign voices per-show in config/schedule.yaml.
Add music styles — Edit mac/content_generator/music_pools_expanded.py to change the AI music generation prompts per show.
