node-webrtc-audio-source
node-webrtc started supporting programmatic audio since version 0.3.6. But it doesn't cover how to get audio stream from microphone.
This library gives you a RTCAudioSource object which streams audio data from microphone.
Install
yarn add node-webrtc-audio-source wrtc
Usage
const RTCAudioSink = nonstandard const rtcAudioSource = const track = rtcAudioSourceconst rtcAudioSink = track rtcAudioSink { // Do something with the received audio samples.}rtcAudioSourcestart // stop after 10 seconds
