or

yarn add react-voice-visualizer

Demo App

For a live demonstration of the React Voice Visualizer library, you can check out the Demo Voice Visualizer App. This app showcases various features and functionalities of the library in action.

Feel free to explore the demo app to see how the React Voice Visualizer can be used in different scenarios. You can refer to the source code of the demo app for additional examples and inspiration for using the library effectively.

Usage

To start using the VoiceVisualizer component, you will need to import the necessary hook and component from the library. Here's an example of how to use this library in your App component:

import { useEffect } from "react";
import { useVoiceVisualizer, VoiceVisualizer } from "react-voice-visualizer";

const App = () => {
    // Initialize the recorder controls using the hook
    const recorderControls = useVoiceVisualizer();
    const {
        // ... (Extracted controls and states, if necessary)
        recordedBlob,
        error,
        audioRef,
    } = recorderControls;

    // Get the recorded audio blob
    useEffect(() => {
        if (!recordedBlob) return;

        console.log(recordedBlob);
    }, [recordedBlob, error]);

    // Get the error when it occurs
    useEffect(() => {
        if (!error) return;

        console.error(error);
    }, [error]);

    return (
        <VoiceVisualizer ref={audioRef} controls={recorderControls} />
    );
};

export default App;

Getting started

  1. Import the required components and hooks from the library.
  2. Initialize the recorder controls using the useVoiceVisualizer hook.
  3. Use the provided state and functions to manage audio recording and playback.
  4. Render the VoiceVisualizer component to display the real-time audio visualization.
  5. Use the provided buttons to start, pause, stop, and save the audio recording.

Remember to include necessary CSS styles to customize the components and buttons according to your design preferences.

API Reference

useVoiceVisualizer() Hook

A hook that provides recorder controls and state for audio visualization.

Usage
const recorderControls = useVoiceVisualizer();
Parameters (All parameters are optional)
ParameterTypeDescription
onStartRecording() => voidCallback function triggered when recording starts.
onStopRecording() => voidCallback function triggered when recording stops.
onPausedRecording() => voidCallback function triggered when recording is paused.
onResumedRecording() => voidCallback function triggered when recording is resumed.
onClearCanvas() => voidCallback function triggered when the canvas is cleared.
onEndAudioPlayback() => voidCallback function triggered when audio playback ends.
onStartAudioPlayback() => voidCallback function triggered when audio playback starts.
onPausedAudioPlayback() => voidCallback function triggered when audio playback is paused.
onResumedAudioPlayback() => voidCallback function triggered when audio playback is resumed.
onErrorPlayingAudio(error: Error) => voidCallback function is invoked when an error occurs during the execution of audio.play(). It provides an opportunity to handle and respond to such error.
Returns
ReturnsTypeDescription
audioRefMutableRefObject<HTMLAudioElement \| null>Reference to the audio element used for playback.
isRecordingInProgressbooleanIndicates if audio recording is currently in progress.
isPausedRecordingbooleanIndicates if audio recording is currently paused.
audioDataUint8ArrayAudio data for real-time visualization.
recordingTimenumberElapsed time during recording in milliseconds.
mediaRecorderMediaRecorder \| nullMediaRecorder instance used for recording audio.
durationnumberDuration of the recorded audio in seconds.
currentAudioTimenumberCurrent playback time of the recorded audio in seconds.
audioSrcstringSource URL of the recorded audio file for playback.
isPausedRecordedAudiobooleanIndicates if recorded audio playback is paused.
isProcessingRecordedAudiobooleanIndicates if the recorded audio is being processed and 'Processing Audio...' text shown.
isClearedbooleanIndicates if the canvas has been cleared.
isAvailableRecordedAudiobooleanIndicates whether recorded audi is available and not currently being processed. This return value can be used to check if it's an appropriate time to work with recorded audio data in your application.
recordedBlobBlob \| nullRecorded audio data in Blob format.
bufferFromRecordedBlobAudioBuffer \| nullAudio buffer from the recorded Blob.
formattedDurationstringFormatted duration time in format 09:51m.
formattedRecordingTimestringFormatted recording current time in format 09:51.
formattedRecordedAudioCurrentTimestringFormatted recorded audio current time in format 09:51:1.
startRecording() => voidFunction to start audio recording.
togglePauseResume() => voidFunction to toggle pause/resume during recording and playback of recorded audio.
stopRecording() => voidFunction to stop audio recording.
saveAudioFile() => voidThis function allows you to save the recorded audio as a webm file format. Please note that it supports saving audio only in the webm format. If you need to save the audio in a different format, you can use external libraries like FFmpeg to convert the Blob to your desired format. This flexibility allows you to tailor the output format according to your specific needs.
clearCanvas() => voidFunction to clear the visualization canvas.
setCurrentAudioTimeDispatch<SetStateAction<number>>Internal function to handle current audio time updates during playback.
errorError \| nullError object if any error occurred during recording or playback.
isProcessingOnResizebooleanIndicates whether audio processing is occurring during a resize event when audio is recorded and a blob is present.
isProcessingStartRecordingbooleanWhen set to true, it indicates that the start recording button has been pressed, but either the permission to record has not yet been granted or the recording itself has not yet commenced. This prop serves as a helpful flag to manage the state of the recording process, allowing components to react accordingly to the current stage of recording initiation.
_setIsProcessingAudioOnCompleteDispatch<SetStateAction<boolean>>Internal function to set isProcessingAudioOnComplete state.
_setIsProcessingOnResizeDispatch<SetStateAction<boolean>>Internal function to set isProcessingOnResize state.
