    + WebRTC Audio Scalable Broadcast using RTCMultiConnection +

    + Use peer-to-peer protocol to broadcast your audio over 20+ users. +

    +

    + +

    +

    + + +
    + + + + + + + +
    +

    How this works?

    +

    + This module simply initializes socket.io and configures it in a way that single audio/video/screen stream can be shared/relayed over unlimited users without any bandwidth/CPU usage issues. Everything happens peer-to-peer! +

    +
