# haunt-fm
|
|
|
|
Personal music recommendation service. Captures listening history from Music Assistant, discovers similar tracks via Last.fm, embeds audio with CLAP, and generates playlists.
|
|
|
|
## Quick Start
|
|
|
|
```bash
|
|
# On NAS
|
|
cd /volume1/homes/antialias/projects/haunt-fm
|
|
docker compose up -d
|
|
docker compose exec haunt-fm alembic upgrade head
|
|
```
|
|
|
|
## Architecture
|
|
|
|
- **FastAPI** app with async SQLAlchemy + asyncpg
|
|
- **PostgreSQL + pgvector** for tracks, embeddings, and vector similarity search
|
|
- **CLAP model** (laion/larger_clap_music) for 512-dim audio embeddings
|
|
- **Last.fm API** for track similarity discovery
|
|
- **iTunes Search API** for 30-second audio previews
|
|
- **Music Assistant** (via Home Assistant REST API) for playback
|
|
|
|
