* refactor: active speakers 1. Observe the loudest adjusted with active ratio instead of linear average of decibel values 2. Follow RFC6465 to convert audio level from decibel to linear value. 3. Quantize audio level for stable slice comparison 4. Switch moving average algorithm from MMA to EMA to have the same center of mass with SMA 5. Minor: remove seenSids map allocation 6. Minor: minimize division arithmetic * Update pkg/rtc/audiolevel.go Co-authored-by: David Zhao <david@davidzhao.com>
LiveKit - Open source, distributed video/audio rooms over WebRTC
LiveKit is an open source project that provides scalable, multi-user conferencing over WebRTC. It's designed to give you everything you need to build real time video/audio capabilities in your applications.
Features
- Horizontally scalable WebRTC Selective Forwarding Unit (SFU)
- Modern, full-featured client SDKs for JS, iOS, Android
- Built for production - JWT authentication and server APIs
- Robust networking & connectivity, over UDP & TCP
- Easy to deploy - pure Go & single binary
- Advanced features - speaker detection, simulcasting, selective subscription, moderation APIs.

Tools:
Installing
From source
Pre-requisites:
- Go 1.15+ is installed
- GOPATH/bin is in your PATH
- protoc is installed and in PATH
Then run
git clone https://github.com/livekit/livekit-server
cd livekit-server
./bootstrap.sh
mage
Docker
LiveKit is published to Docker Hub under livekit/livekit-server
Running
Creating API keys
LiveKit utilizes JWT based access tokens for authentication to all of its APIs. Because of this, the server needs a list of valid API keys and secrets to validate the provided tokens. For more, see Access Tokens guide.
Generate API key/secret pairs with:
./bin/livekit-server generate-keys
or
docker run --rm livekit/livekit-server generate-keys
Store the generate keys in a YAML file like:
APIwLeah7g4fuLYDYAJeaKsSE: 8nTlwISkb-63DPP7OH4e.nw.J44JjicvZDiz8J59EoQ+
Starting the server
In development mode, LiveKit has no external dependencies. With the key file ready, you can start LiveKit with
./bin/livekit-server --key-file <path/to/keyfile> --dev
or
docker run --rm -e LIVEKIT_KEYS="<key>: <secret>" livekit/livekit-server --dev
the --dev flag turns on log verbosity to make it easier for local debugging/development
Sample client
To test your server, you can use our example web client (built with our React component)
Enter generated access token and you are connected to a room!
Creating a JWT token
To create a join token for clients, livekit-server provides a convenient subcommand to create a development token. This token has an expiration of a month, which is useful for development & testing, but not appropriate for production use.
./bin/livekit-server --key-file <path/to/keyfile> create-join-token --room "myroom" --identity "myidentity"
Deploying for production
LiveKit is deployable to any environment that supports docker, including Kubernetes and Amazon ECS.
See deployment docs at https://docs.livekit.io/guides/deploy
