# lonelyradio
> TCP radio for singles
Radio that uses unencrypted TCP socket for broadcasting tagged audio data.
Broadcast audio over the internet.
Decodes audio streams using [symphonia](https://github.com/pdeljanov/Symphonia).
## Install
Optionally transcodes audio into and from FLAC using [flacenc-rs](https://github.com/yotarok/flacenc-rs/) and [claxon](https://github.com/ruuda/claxon).
## Installation
### Install music server
```shell
cargo install lonelyradio
cargo install --git https://github.com/ivabus/lonelyradio --tag 0.5.0 lonelyradio
```
## Build
### Install CLI client
```shell
cargo build -r
cargo install --git https://github.com/ivabus/lonelyradio --tag 0.5.0 monoclient
```
### Install GUI (Slint) client
```shell
cargo install --git https://github.com/ivabus/lonelyradio --tag 0.5.0 monoclient-s
```
## Run
```
lonelyradio <MUSIC_FOLDER> [-a <ADDRESS:PORT>] [-p] [-w] [-m|--max-samplerate M]
lonelyradio [-a <ADDRESS:PORT>] [-p|--public-log] [-w|--war] [-m|--max-samplerate M] [--xor-key-file FILE] [--no-resampling] [-f|--flac] <MUSIC_FOLDER>
```
All files (recursively) will be shuffled and played back. Public log will be displayed to stdout, private to stderr.
`-m|--max-samplerate M` will resample tracks which samplerate exceeds M to M
`--xor-key-file FILE` will XOR all outgoing bytes looping through FILE
`-f|--flac` will enable (experimental) FLAC compression
### Clients
[monoclient](./monoclient) is a recommended CLI client for lonelyradio that uses [monolib](./monolib)
[monoclient](./monoclient) is a recommended CLI player for lonelyradio that uses [monolib](./monolib)
```shell
monoclient <SERVER>:<PORT>
```
[monoclient-s](./monoclient-s) is a experimental GUI player for lonelyradio built with [Slint](https://slint.dev)
```shell
monoclient-s
```
Desktop integration will be added later.
### Other clients
SwiftUI client is availible in [platform](./platform) directory.
[monolib](./monolib) provides lonelyradio-compatible C API for creating custom clients.
[monoloader](./monoloader) is a tool, that allows you to download individual audio tracks from lonelyradio-compatible servers.
[monolib](./monolib) provides a C API compatible with lonelyradio for creating custom clients.
#### monolib API stability
As lonelyradio has not yet reached its first major release, the API may (and will) break at any point.
### Microphone server
Experimental server (lonelyradio-compatible) for streaming audio from your microphone is available in the [microserve](./microserve) crate.
