WeaveSignal: an internet radio station with a live studio (community package)

[LoudLemur]

Hello all,

WeaveSignal is a new open-source (AGPL-3.0) internet radio and video station that runs as one Cloudron app. It puts the live studio in the same installation as playout and the stream:

• Presenters, guests and callers talk in one room from a browser (LiveKit inside the app). Each person hears a mix of everyone but themselves.
• Listeners call in from the station's page: no phone number. A screener talks to them off air and sends them to the desk.
• Liquidsoap 2.5 fills the hours between shows from a schedule. There's a dead-air fallback.
• Listeners get Ogg Opus, an optional MP3 stream, and HLS video when it's on.
• A live chat with moderation, podcast feeds and show cards.
• A desktop studio app (Linux, Windows) runs the desk and the screener.

Install in a few clicks: it's listed on ca.cloudron.io (https://ca.cloudron.io/app/top.weavesignal.cloudronapp). In your dashboard, open App Store → Community apps, paste
https://forgejo.weavesignal.top/WeaveSignal/weavesignal/raw/branch/main/deploy/cloudron/CloudronVersions.json
and install (Cloudron 10.0 or later). Updates arrive through the same catalogue, and Cloudron's backups cover the station's data and database.

See it first: a three-and-a-half-minute video of a show going to air, a caller screened and a swear dumped, on https://weavesignal.top, and everything it does on https://weavesignal.top/features/

What the package needs:

• Four domains: the studio behind Cloudron's login, plus the listener stream, the room's signalling and the public pages.
• A UDP port for the room's media (7882 by default) and TCP 15349 for TURN over TLS, because Cloudron's own TURN holds 5349.
• PostgreSQL and sendmail.
• A 1.5 GiB memory limit. It measured 0.5–0.7 GiB under a test load.

Things worth knowing:

• Live audio needs a server that isn't overloaded. On a busy shared Cloudron the listener feed ran dry; on an idle 4-vCPU server it held for 13 hours.
• TURN over IPv6 doesn't work yet. LiveKit's built-in TURN refuses clients that reach it over IPv6, and a Cloudron app domain gets an AAAA record whenever the server has IPv6. Relay-only clients on IPv6 networks can't join (upstream: livekit/livekit#5131).
• It's release 1.0.0 and new. What is proven and what isn't is on the status page: https://weavesignal.top/docs/reference/release-one-status/
