import ScreenAudioRecorder, { Options } from 'react-native-screen-audio-recorder';

const options: Options = {
  sampleRate: 16000,
  channels: 1,
  bitsPerSample: 16,
  fileName: 'novo.wav',
  fromMic: false,
  saveFile: false,
  audioEmitInterval: 1000
};

ScreenAudioRecorder.init(options);

ScreenAudioRecorder.start();

ScreenAudioRecorder.on('data', data => {
  // real time base64-encoded audio
});

const audioFile = await AudioRecord.stop();
