See an usage example bellow:

import { AudioVisualizerStatus, useAudioVisualizerContext } from 'react-audio-visualizers-core';

export const YourVisualizer = () => {
  const { audioContext, analyser, status } = useAudioVisualizerContext();
  const dataArray = new Uint8Array(analyser ? analyser.frequencyBinCount : 0);

    if (analyser && audioContext && status === AudioVisualizerStatus.playing) {
      analyser.getByteTimeDomainData(dataArray);

      // do stuff with dataArray
    }

    // render <AudioVisualizer> ...
};
