# webrtc-radio

Radio web app which broadcasts audio across your local network using:

* WebRTC

* Angular 8.2.x

* NodeJS 10.16.x

* socket.io 2.3.x

Note: This project supports multiple broadcasts with peer-to-peer communication, which is complex. If you only need a single audio broadcast server, check out https://github.com/meetecho/janus-gateway in particular this example https://janus.conf.meetecho.com/streamingtest.html

## Installation

Install dependencies using:

    npm install

Generate an SSL key and certificate using:

    npm run generate

## Usage

Run production HTTPS and Socket.io local servers using:

    npm start

Access the web frontend at:

    https://localhost:8080

## Development with live reload

In seperate terminals run the dev servers using:

    npm run dev:backend

    npm run dev:frontend

Go to both urls and allow unsafe browser access to https at:

    https://localhost:8080

    https://localhost:4200

Then develop using the live reload page at:

    https://localhost:4200

## Understanding SDP output

Create a file containing the SDP data called:

    sdp.txt

To then convert into a human readable structured output run:

    npm run parser

Then open the generated file:

    sdp.json

## Limitations

1) Maximum bitrate is 520kb/s stereo, which is 260kps per channel.

2) Actual bitrate depends on the speed of your network and strength of your signal.
