Example

import * as lfo from 'waves-lfo/client';

// assuming a stream from the microphone
const source = audioContext.createMediaStreamSource(stream);

const audioInNode = new lfo.source.AudioInNode({
  sourceNode: source,
  audioContext: audioContext,
});

const slicer = new lfo.operator.Slicer({
  frameSize: frameSize,
  hopSize: hopSize,
  centeredTimeTags: true
});

const power = new lfo.operator.RMS({
  power: true,
});

const segmenter = new lfo.operator.Segmenter({
  logInput: true,
  filterOrder: 5,
  threshold: 3,
  offThreshold: -Infinity,
  minInter: 0.050,
  maxDuration: 0.050,
});

const logger = new lfo.sink.Logger({ time: true });

audioInNode.connect(slicer);
slicer.connect(power);
power.connect(segmenter);
segmenter.connect(logger);

audioInNode.start();
