SUB/WAVE brings AI DJ to self-hosted radio

Key takeaway

• SUB/WAVE is a self-hosted radio station generator that uses an AI DJ to curate and broadcast tracks from your personal music library on a single shared stream, with support for multiple LLM providers and text-to-speech engines.

• It is designed for operators who want radio-style curation (one shared broadcast, no skip button for listeners) rather than playlist-based streaming, and it runs on a single Linux host behind optional Cloudflare.

FAQ

What music does the AI play, and where does it come from?

The AI plays only from your own music library, pulled from Navidrome over the Subsonic API. It does not generate music, replace your taste, or draw from an external catalogue.

Can listeners skip songs or control what plays next?

No. Listeners cannot skip; track-end is the only natural transition. The DJ (AI plus operator-curated personas) owns the pacing. Operators can skip via the admin API, but listeners cannot.

What LLM providers and text-to-speech options are supported?

The LLM provider is swappable at runtime among Ollama, Anthropic, OpenAI, Google, DeepSeek, OpenRouter, Vercel AI Gateway, or any OpenAI-compatible server. Five TTS engines are available: Piper and Kokoro in-process, plus optional Chatterbox (zero-shot voice cloning) and PocketTTS (6× real-time, EN/FR/DE/IT/ES/PT) in a sidecar, and cloud options from OpenAI or ElevenLabs.

How do listeners access the broadcast?

Listeners connect via a single shared Icecast stream using native iOS or Android apps (available on the App Store and Google Play), a web player, or a PWA. The broadcast simultaneously serves MP3 128 kbps and Ogg-Opus 96 kbps so the player can pick the best codec.
