Raw

Radio

What it is

Using this web server, and this WASM audio player along with some other assets from past projects this is a web based radio.
You should be able to join in the browser and listen to a selection of seamlessly streamed audio files (streamed via websockets).

Demo: https://erewhon.xyz/radio

Config

Put a .config file in the same directory as the server, the server is configured as such:

TLS: yes
FULLCHAIN: /home/me/ssl/fullchain.cer
PKEY: /home/me/ssl/example.abc.key

PORT: 80
TLS_PORT: 443

SERVER_THREADS: 10

RADIOS: { "station 1 name", "station 1 directory" }, { "station 2 name", "station 2 directory" }

Stuff used

JSON (https://github.com/nlohmann/json.git)
Thread safe queue (https://github.com/cameron314/readerwriterqueue)
libcurl (for parsing URLs)
OpenSSL (for base64 encoding)
liburing (for the wrapper over io_uring)
WolfSSL (for TLS)
Opus (https://github.com/xiph/opus) (compiled to WebAssembly)
Bootstrap 5.0 (for some modals/dropdowns in the UI)
Google Fonts (for the icons in the UI)
emsdk (https://github.com/emscripten-core/emsdk) (for the WebAssembly stuff)

Fixes

  • If inotify isn't working properly, raise the max_user_instances: sudo sysctl fs.inotify.max_user_instances=8192
  • If you're getting TCP RST packets when using a reverse proxy like NGINX, then make sure to remove any reference to keepalive_timeout 0; in the location / block or wherever you're setting up the reverse proxy stuff
