How to Record and Play Audio in React Native

Welcome to the world of audio recording and playback in React Native! Today, we’re delving into the react-native-audio-recorder-player library. This module allows developers to effortlessly integrate audio recording and playback functionalities within their mobile applications on both Android and iOS platforms. So, let’s illuminate the path to becoming an audio wizard! ✨

Getting Started

Before diving into coding, ensure you have the following prerequisites:

• Node.js installed
• React Native environment set up
• A mobile device or simulator for testing

Installation Steps

To kickstart using the audio recorder player module, follow these steps:

$ yarn add react-native-audio-recorder-player

iOS Installation

For iOS, you need to run the following command:

$ npx pod-install

Android Installation

If you’re on React Native version 0.60 and above, you can link the package automatically. Otherwise, you’ll have to do it manually by modifying files as outlined in the post installation guide.

Basic Usage

Once you’ve got everything installed, let’s see how you can start recording and playing audio.

Here’s how to set up the recorder:

import AudioRecorderPlayer from 'react-native-audio-recorder-player';

const audioRecorderPlayer = new AudioRecorderPlayer();

const onStartRecord = async () => {
    const result = await audioRecorderPlayer.startRecorder();
    console.log(result);
};

const onStopRecord = async () => {
    const result = await audioRecorderPlayer.stopRecorder();
    console.log(result);
};

Playing Audio

To play the recorded audio, you can do the following:

const onStartPlay = async () => {
    const msg = await audioRecorderPlayer.startPlayer();
    console.log(msg);
};

const onStopPlay = async () => {
    await audioRecorderPlayer.stopPlayer();
};

Understanding the Logic: An Analogy

Think of the audio recorder and player like a bakery:

• Just like baking bread, you have to prepare your ingredients (like startRecorder and stopRecorder methods) before you create the final loaf.
• The oven represents the mobile device that processes baking (recording/playing audio) while the golden brown crust signifies the successful audio file that results from your efforts.
• Lastly, just as you may taste the bread to adjust flavors, you can monitor your recording by using listeners to check the current position and meter readings.

Troubleshooting Tips

If you encounter issues while using the library, here are some troubleshooting ideas:

• Ensure you have the appropriate permissions set in AndroidManifest.xml for recording audio.
• Check your Info.plist file for microphone usage description in iOS.
• Update your SDK settings if you face compatibility issues.
• If you can’t get the audio file path, using packages like react-native-blob-util can assist in file management.
