react-audio-voice-recorder

react-audio-recorder

An audio recording helper for React. Provides a component and a hook to help with audio recording.

Installation

npm install react-audio-recorder

Usage

AudioRecorder Component

You can use an out-of-the-box component that takes onRecordingComplete method as a prop and calls it when you save the recording

import React from "react";
import ReactDOM from "react-dom/client";
import AudioRecorder from "react-audio-recorder";

const addAudioElement = (blob: Blob) => {
  const url = URL.createObjectURL(blob);
  const audio = document.createElement("audio");
  audio.src = url;
  audio.controls = true;
  document.body.appendChild(audio);
};

ReactDOM.createRoot(document.getElementById("root")).render(
  <React.StrictMode>
    <AudioRecorder onRecordingComplete={addAudioElement} />
  </React.StrictMode>
);

---

useAudioRecorder hook

If you prefer to build up your own UI but take advantage of the implementation provided by this package, you can use this hook instead of the component

The hook returns the following:

startRecording

Calling this method would result in the recording to start. Sets isRecording to true

stopRecording

This results in a recording in progress being stopped and the resulting audio being present in recordingBlob. Sets isRecording to false

togglePauseResume

Calling this method would pause the recording if it is currently running or resume if it is paused. Toggles the value isPaused

recordingBlob

This is the recording blob that is created after stopRecording has been called

isRecording

A boolean value that represents whether a recording is currently in progress

isPaused

A boolean value that represents whether a recording in progress is paused

recordingTime

Number of seconds that the recording has gone on. This is updated every second

Sample usage of hook

  const {
    startRecording,
    stopRecording,
    togglePauseResume,
    recordingBlob,
    isRecording,
    isPaused,
    recordingTime,
  } = useAudioRecorder();

Combine the useAudioRecorder hook and the AudioRecorder component

This is for scenarios where you would wish to control the AudioRecorder component from outside the component. You can call the useAudioRecorder and pass the object it returns to the recorderControls of the AudioRecorder. This would enable you to control the AudioRecorder component from outside the component as well

Sample usage

import AudioRecorder from "./components/AudioRecordingComponent";
import useAudioRecorder from "./hooks/useAudioRecorder";

const ExampleComponent = () => {
  const recorderControls = useAudioRecorder()
  const addAudioElement = (blob) => {
    const url = URL.createObjectURL(blob);
    const audio = document.createElement("audio");
    audio.src = url;
    audio.controls = true;
    document.body.appendChild(audio);
  };

  return (
    <div>
      <AudioRecorder 
        onRecordingComplete={(blob) => addAudioElement(blob)}
        recorderControls={recorderControls}
      />
      <button onClick={recorderControls.stopRecording}>Stop recording</button>
    </div>
  )
}
