A simple reverse proxy that muxes ICY metadata into an audio stream.
Some webradios don't expose the current song metadata in the audio stream, relying instead on a separate API. This prevents third party players from displaying the information. IcyProxy acts as a man-in-the-middle proxy that fetches both the audio stream and the metadata, and muxes them together.

Run docker run -ti --rm -v /path/to/your/sources.json:/sources.json:ro -p 8080:8080 ghcr.io/abustany/icyproxy:latest icyproxy /sources.json
Run go build -o . ./cmd/icyproxy
The icyproxy binary will be in the root directory.
Run nix build
The icyproxy binary will be in result/bin.
IcyProxy relies on a JSON configuration file to know how to fetch the audio and metadata for a given station. Several stations can be configured on a same server. There is an example config file in examples/sources.json.
You can then simply run icyproxy sources.json to start the server.
Run icyproxy -help for more command line options.
