SUB/WAVE: Internet Radio

The DJ doesn't just queue songs. It picks the next track, reads the station ident, delivers a time check and the weather, and gives a short intro on the way into whatever's playing next. It never cuts between tracks in silence. Each station can hold several personas, and each persona has its own voice, so a late-night show can sound different from the afternoon one. Voices are swappable, and the project supports cloned voices if you want a specific sound.

Listeners type or say what they want and the DJ figures out the intent. Ask for "something slower" or name a track directly and it gets slotted into the broadcast. There's no per-listener queue to manage because there's only one stream. Requests land in the booth log so the operator can see what came in and how the DJ answered.

SUB/WAVE runs a single Icecast stream, so every listener hears the same broadcast at the same time. No shuffle, no skip button, no "up next for you." That design choice is the product. It makes the station feel live and gives the AI DJ a reason to exist, since a person can't talk over 300 separate playlists.

The admin side covers the operational basics. Dash shows live status, the current queue, and the booth log. Personas manages the DJ roster and their voices. Schedule lets you programme the week an hour at a time. Skills controls what the DJ does between tracks. Stats surfaces LLM and text-to-speech usage at a glance, and Debug shows health, logs, and recent model calls.

The Observatory is a data-art map of every track the DJ has tagged, laid out by genre and lit by energy. Click a point and you get a full dossier on that track: BPM, key, mood, embeddings, and nearest neighbours. It's more than a gimmick. It's how you see whether your tagging is landing where you expect.

The listener player ships as web, iOS, and Android apps plus a native macOS, Windows, and Linux desktop build. The apps include now-playing art and a live visualiser, the booth view, a scrollable timeline of what's played, requests, the upcoming schedule, and themes that recolour the app to match the station. The mobile app supports AirPlay, Google Cast, and a sleep timer.

If running a language model is the part you'd rather skip, SUB/WAVE DJ Brain is a metered brain and optional cloud voice for a station you still self-host: one key, pasted once, from £5 a month. SUB/WAVE Hosted runs the whole station for you at yourname.getsubwave.com. Both fund the project, and the self-hosted software stays complete and free either way.
