# Personal internet radio: Agentic AI DJ > Source: > Published: 2026-06-25 14:34:54+00:00 **A personal internet radio station.** One Icecast stream, one broadcast. Every listener hears the same thing at the same time. An AI DJ picks the tracks and talks between them: station idents, time checks, the weather, a quick intro for whatever's going out next. You can ask for music in plain language; the DJ works out what you meant and slots it in. It's *radio*, not a playlist. No per-listener shuffle, no skip button, no "up next for you." You tune in and hear whatever is on. ## SUBWAVE.Showreel.1080p.mp4 **Project site**—[getsubwave.com](https://www.getsubwave.com/)** Demo player**—[getsubwave.com/listen](https://www.getsubwave.com/listen)** Mobile apps**— native players —[iOS on the App Store](https://apps.apple.com/app/sub-wave/id6778786696),[Android on Google Play](https://play.google.com/store/apps/details?id=com.getsubwave.app)**Setup walkthrough**—[getsubwave.com/setup](https://www.getsubwave.com/setup)** Operator manual**—[getsubwave.com/manual](https://www.getsubwave.com/manual)** Community**—[join the Discord](https://discord.gg/vjVbVKnMBa) **The listener player.** One shared broadcast, with in-app song requests. **The admin console.** Where the operator runs the station. **The Library Observatory.** A data-art map of every track the DJ has tagged, placed by genre and lit by energy. Click a point for its full dossier: BPM, key, mood, embeddings, and nearest neighbours. Open it at `/observatory` . **One shared Icecast stream.** Every listener hears the same broadcast at the same time.**AI DJ that picks and talks.** Curates tracks, writes intros, and reads station idents, the time, and the weather.**Plain-language requests.**"Play something more upbeat" or "anything by Radiohead" works.** Your own music library.**Pulls from Navidrome over the Subsonic API. No external catalogue.** Swappable LLM provider.**Ollama, Anthropic, OpenAI, Google, DeepSeek, OpenRouter, Vercel AI Gateway, or any OpenAI-compatible server. Change it from the admin UI with no redeploy.**Five TTS engines.** Piper and Kokoro in-process for fast local speech, plus an optional`tts-heavy` sidecar (`docker compose --profile tts-heavy up -d` ) that adds Chatterbox (zero-shot voice cloning) and PocketTTS (6× real-time, EN/FR/DE/IT/ES/PT). Cloud (OpenAI / ElevenLabs) is also available. Pick a different engine per kind of speech.**Multiple DJ personas.** Up to 10 souls in rotation, each with its own voice and writing style.**Dual-codec broadcast.** MP3 128 kbps for Sonos, hardware radios, and cars; Ogg-Opus 96 kbps for modern browsers. The web player picks automatically.**Native apps and PWA.** Native iOS (on the App Store) and Android (on Google Play) players — background audio, lock-screen / CarPlay / Android Auto controls, multi-station — plus an installable PWA on phone and desktop.**Scheduled shows.** A 24×7 grid; each slot has its own persona, mood, and skills.**Pluggable skills.** The DJ's between-track segments — weather, news, traffic, and your own — are skills. The built-ins are scaffolded as editable files under`state/skills//` on first boot, so you can rewrite a brief or change the news feed (BBC → your own RSS) right from the admin console — no code, no redeploy. Add your own by dropping a`SKILL.md` (plus optional data-fetching code) into`state/skills/` , hitting Rescan, and enabling it. See.`docs/custom-skills.md` **Mood-aware rotation.** Time of day, weather, and festival days bias what gets played and how the DJ talks.**Hourly archives.** Every hour saved as MP3 for later replay.**Crossfade + voice ducking.** Tracks blend smoothly; the music ducks under DJ speech and lifts back up.**Admin console.** Live status, queue, booth log, personas, shows, skills, stats, and a debug view of recent LLM calls.**Library Observatory.** A full-screen, data-art map of every tagged track at`/observatory` — placed by genre, lit by energy, with a full dossier per track (BPM, key, mood, embedding fingerprints, and nearest-in-vector-space neighbours). Scales from a few hundred to tens of thousands of tracks.**MCP server.** External agents (Claude Desktop, Cursor, etc.) can request songs and drive the DJ.**Self-hosted.** One`docker compose up -d` on a single Linux host. Optional Cloudflare in front for TLS. A playlist is a list you control. Radio is a broadcast you join. SUB/WAVE is the second kind: **One shared stream.** A single Icecast mount everyone connects to. Everyone hears the same audio at the same instant. That's what makes it a station instead of a jukebox.**No skip.** Track-end is the only natural transition. The DJ — human-curated personas plus an LLM — owns the pacing, not the listener. (Operators*can*skip via the admin API; listeners cannot.)**AI as the DJ, not the catalogue.** The music is your own library, served by Navidrome over the Subsonic API. The LLM picks what's next and talks between tracks. It doesn't generate music and it doesn't replace your taste.**Self-hosted and swappable.** Runs on one Linux box behind Cloudflare. The LLM provider is swappable at runtime (Ollama, Anthropic, OpenAI, Google, OpenRouter, Vercel AI Gateway) with no redeploy. ``` curl -fsSL https://cli.getsubwave.com | sh # installs, then offers to init + start subwave setup # connect Navidrome + LLM ``` Two Enter prompts during the installer (`Run subwave init now?` , then `Bring the stack up now?` ) and the stack is on-air. `subwave setup` connects Navidrome and your LLM, or do the same in the browser at `http://localhost:7700/onboarding` . No clone, no Node on the host. `subwave status / logs / doctor / update` work from anywhere afterwards. If you'd rather skip our binary on your host and stick to `docker compose` : ``` mkdir subwave && cd subwave curl -O https://raw.githubusercontent.com/perminder-klair/subwave/main/docker-compose.yml curl -O https://raw.githubusercontent.com/perminder-klair/subwave/main/.env.example mv .env.example .env # Edit .env: set ADMIN_USER, ADMIN_PASS, SITE_URL (three vars, that's it). docker compose up -d # Then open https://your-host/onboarding. The web wizard collects Navidrome, # LLM, TTS, DJ persona, and offers to render jingles. ``` Functionally identical: same images, same state layout, same persistence. The CLI just saves you the curl-and-edit dance and gives you `subwave logs` , `subwave doctor` , etc. for the rest of the lifecycle. Chatterbox (zero-shot voice cloning) and PocketTTS (fast multilingual) live in a separate `subwave-tts-heavy` sidecar that adds ~5–6 GB of PyTorch and is **not** started by default. To enable: ``` docker compose --profile tts-heavy up -d ``` The controller is wired up to discover the sidecar automatically. Stop it again with `docker compose --profile tts-heavy stop tts-heavy` ; the rest of the stack keeps running and Chatterbox/PocketTTS personas silently fall back to Piper. The old `docker build --build-arg WITH_CHATTERBOX=1` path still works if you already have a custom-built controller image — see `docker/Dockerfile.controller` . ``` git clone https://github.com/perminder-klair/subwave.git && cd subwave ./scripts/setup.sh # scaffolds a 3-var root .env + state/ docker compose -f docker-compose.dev.yml up -d # Broadcast (icecast2 + liquidsoap) + Controller cd web && npm install && npm run dev # web UI on :7700, separate and hot-reloading # Then http://localhost:7700/onboarding to finish configuration. ``` Dev compose bind-mounts `controller/src/` , `radio.liq` , and `sounds/` from the repo. Controller runs under `tsx watch` so `src/**` edits hot-reload inside the container; `radio.liq` edits just need a `docker compose -f docker-compose.dev.yml restart broadcast` . The standalone `subwave` CLI works inside the cloned repo too. `cd subwave && subwave start dev` does the right thing. The contributor convenience is `npm start` , which `tsx` -runs the CLI source directly so unreleased changes are exercised. Same commands, same flags, no `npm install -g` needed. The same CLI doubles as the console for running the station. Run `npm start` for a status-aware menu; every menu action is also a one-shot subcommand, appended after `npm start --` : ``` npm start # interactive operator console (status-aware menu) npm start -- setup # first-boot wizard: Navidrome, LLM, admin, env files npm start -- status # compose env, services, now-playing, recent events npm start -- doctor # full diagnostic sweep npm start -- start dev # docker compose up -d (dev or prod) npm start -- restart broadcast # plain restart (radio.liq is bind-mounted in dev) npm start -- restart controller # rebuild + recreate (source is COPY-d at build) npm start -- logs controller # tail one service npm start -- listen # open the web player in a browser npm start -- admin # open the admin console in a browser npm start -- stop # docker compose down (confirms first) ``` Single Linux host, Cloudflare terminating TLS, Caddy routing to four internal services. The [no-CLI quickstart above](#quick-start-no-cli-raw-docker) is the canonical path: `curl` two files, fill in three vars, `docker compose up -d` , finish setup in the browser. See for host prerequisites, Cloudflare setup, updates, and backup. `DEPLOY.md` **On Unraid?** One-click install from ** Community Applications** (search **SUB/WAVE** in the Apps tab) — or run the full split-container stack via the Compose Manager Plus plugin. Both in **.** `docs/unraid.md` **Bring your own reverse proxy.** If you already run Traefik, nginx, or your own Caddy in your homelab, swap the bundled-Caddy compose for the BYO variant: ``` docker compose -f docker-compose.byo.yml up -d ``` That exposes the web UI on `:7700` , the controller API on `:7701` , and the Icecast stream on `:7702` (all configurable). Point your proxy at those three. `docker/Caddyfile` is a working reference for the route table you need to replicate. Details in [ DEPLOY.md](/perminder-klair/subwave/blob/develop/DEPLOY.md#bring-your-own-reverse-proxy). **Images on GHCR.** Tagged releases publish to `ghcr.io/perminder-klair/subwave-{caddy,broadcast,controller,web}` .

SUB/WAVE streams with`format=raw` so the transcode limits never throttle the radio, and when`sonicSimilarity` is enabled the picker automatically folds Navidrome's audio-based neighbours in as an extra track-selection source — no config, capability-probed, and a silent no-op when the extension is absent. Any reasonably recent Navidrome still works.- Several areas (queue/playback path, `radio.liq` , the crossfade, voice ducking, the LLM layer) have**non-obvious constraints** that are easy to regress.

It does **not** grant you any rights to the music you broadcast through it, and it ships with no licensed content. Owning a file — a purchased download, a CD you ripped, anything in your Navidrome library — covers your own private listening. It does **not** cover **public performance**. The moment SUB/WAVE streams to anyone but you, you are publicly performing copyrighted works, which in most countries requires licences for *two* separate rights: - the **musical composition**(songwriting) — e.g. PRS for Music (UK), ASCAP / BMI / SESAC (US); - the **sound recording**(the master) — e.g. PPL (UK), SoundExchange (US, under the statutory webcasting licence and its DMCA §114 conditions). You are the broadcaster and you are solely responsible for clearing those rights. If you don't want to obtain licences, run the station privately (see [DEPLOY.md → Make the station private](/perminder-klair/subwave/blob/develop/DEPLOY.md#make-the-station-private-cloudflare-access)), or broadcast only content you're cleared to use — music you created or own the rights to, Creative-Commons-licensed tracks, royalty-free libraries, or public-domain recordings. This is general information, not legal advice. If you run a public station, talk to a media/IP lawyer in your jurisdiction. [MIT](/perminder-klair/subwave/blob/develop/LICENSE).
