React Native audio recording module used for DSP with Android + iOS

Install

$ npm i react-native-recording

Usage

import { PermissionsAndroid } from "react-native";
import Recording from "react-native-recording";

await PermissionsAndroid.requestMultiple([
  PermissionsAndroid.PERMISSIONS.RECORD_AUDIO,
]);

Recording.init({
  bufferSize: 4096,
  sampleRate: 44100,
  bitsPerChannel: 16,

Microphone request for iOS 10 and above

As of iOS 10.0, you must declare an intention to access a microphone. Add NSMicrophoneUsageDescription key and declaration value in Info.plist.

<dict>
    ...
	<key>NSMicrophoneUsageDescription</key>
	<string>This app uses the microphone to record the soundscape.</string>
    ...

react-native-recording's Issues

Callback not firing on iOS

The same build worked two weeks ago. But when we tested it today it won't fire callbacks on iOS.

Actually, it will fire just once with an empty array.

It happens on multiple versions of iOS (we checked 14.0, 14.5, and 15 beta). (at least 14.0 worked two weeks ago). And I cannot reproduce it in ios emulator.

Are you experiencing similar issues?

EventListener not working once stop is called.

I am using the Recording module to stream data to PC over websocket as below. But the data is getting sent only once. If I press start for the second time , keypress in sent to PC but no voice data sent as the eventlistener not getting called. What am i doing wrong here?

import React from 'react';
import {Component,Text,View,Button, Alert } from 'react-native';
import Recording from 'react-native-recording';

export default class VoiceScreen extends React.Component {
constructor(){
super();
this.state={
status:true
}
}
componentDidMount(){
//await this.checkPermission();
Recording.init({
  bufferSize: 640,

  sampleRate: 16000,

  bitsPerChannel: 16,

  channelsPerFrame: 1,

})

Recording.addRecordingEventListener(this.DataHandler);

ws.onmessage=(m)=>
{
  console.log(m.data +"status "+this.state.status);
  if(m.data=='READY')
  {
    this.startVoice();
  }
  else
  {
    this.stopVoice();
  }
}
}

startVoice(){
Recording.start();
}

stopVoice()
{
Recording.stop();
}

DataHandler=(data)=>{
  console.log(" Sending auido data of len "+data.length*2);
  var pcm_len = data.length*2;
  //data.unshift(pcm_len>>8);
  data.unshift(pcm_len);
  data.unshift(0x03);
  var view = new Uint16Array(data);

  //var view1 = new Uint8Array(view);
  ws.send(view);
  data.pop();
  data.pop();
}

sendVoiceKeyPress(){
cmd = [];
cmd.push(0x04);
cmd.push(0x00);
cmd.push(0x05);
cmd.push(0x00);

ws.send(start_speech);

this.setState({status:false});
}

sendVoiceKeyRelease(){
this.stopVoice();
cmd = [];
cmd.push(0x05);
cmd.push(0x00);

How to reduce the size to 5.17 KiB/s?

The issue

My goal is to send a data array with size 5.17 KiB/s to a WebSocket.

I have not tried it yet, currently I tried to save the audio to a file. I use RNSaveAudio to save the audio file. I also use react-native-fs to get the app's folder path.

My expected result is the file should be around 5 - 6 kB for 1 seconds of audio.

My actual result is: 8236 bytes for 93 milliseconds (roughly 0,093 seconds) of audio. I tried to change the sampleRate to 8000. I found the data size to be 2 - 3 times larger compared to Opus Voice with bit rate 5.17 KiB/s and sampling rate 8 kHz.

TL:DR

Steps to reproduce:

Add listener

  let audioInt16: number[] = [];
  let listener;

  React.useEffect(() => {
    // eslint-disable-next-line react-hooks/exhaustive-deps
    listener = Recording.addRecordingEventListener((data: number[]) => {
      console.log('record', data.length);
      // eslint-disable-next-line react-hooks/exhaustive-deps
      audioInt16 = audioInt16.concat(data);
    });

    return () => {
      listener.remove();
    };
  });

Record audio

  const startAsync = async () => {
    await PermissionsAndroid.requestMultiple([
      PermissionsAndroid.PERMISSIONS.RECORD_AUDIO,
    ]);

    Recording.init({
      bufferSize: 4096,
      sampleRate: 44100,
      bitsPerChannel: 16,
      channelsPerFrame: 1,
    });

    Recording.start();
  };

Save audio

  const saveAudio = async () => {
    const promise = await RNSaveAudio.saveWav(path, audioInt16);
    console.log('save audio', promise, path);
  };

Play audio

  const playAudio = () => {
    if (player.canPrepare || player.canPlay) {
      player.prepare((err) => {
        if (err) {
          console.log(err);
        }
        console.log('play audio', player.duration);
        player.play();
      });
    }
  };

TypeError: null is not an object (evaluating 'Recording.init')

I get the error "TypeError: null is not an object (evaluating 'Recording.init')" during

	useEffect(() => {
		Recording.init({
			bufferSize: 4096,
			sampleRate: 44100,
			bitsPerChannel: 16,
			channelsPerFrame: 1,
		});
        })

Please help.

Recording Blocking UI

When I run a recording instance on my iPhone, my react-native UI gets blocked. It seems to me that since events are generated on incoming data from the audio codec, and the events are dispatched to the main thread, my react program gets stuck dealing with the recording data, instead of doing other things.

For instance, when I add the following lines of code Recording.addRecordingEventListener(datab => this.circularBuff.enqueue(datab)); which esentially adds data to a buffer, I am not able to trigger the Recording.Stop() method from my UI with touch input. On android, there is a lag after I try and stop a recording.

My goal is to be able to detect an impulse from a small amount of buffered data using JS.

How to find real-time audio level

 for (let d = 0; d < this.globalBuffer.length; d++) {
      rms += this.globalBuffer[d] * this.globalBuffer[d];
    }

 rms = Math.sqrt(rms / this.globalBuffer.length);

I use this algorithm which called root-mean-square It basically calculates the amount of signal in the buffer but when there is no sound it gives values which are more than 0.

My question: What is the proper way to determine input audio level in react native by using this library?

Note: I'm trying to implement this tuner to my react native app it is written with javascript web audio api

Recorder cannot record more than 1 time if audio is played after recording (iOS)

Hello, first of all thank you for the wonderful library! I am making an app which needs DSP and this has been such a life saver.

I'm having an issue with the recorder. Here is a high level of what the app is should be doing:

Record audio
Play a sound
Record audio again

In step 3, I am getting nothing sent to the recorder's event listener (specifically, one empty buffer ( [] ) upon starting recording, and another upon ending recording)

Here is my code:

Starting Recording:

this.Recorder = require('react-native-recording').default;

        this.Recorder.init({
            bufferSize: constants.bufferSize,
            sampleRate: constants.sampleRate,
            bitsPerChannel: constants.bitsPerChannel,
            channelsPerFrame: constants.channelsPerFrame,
        });

        this.Listener = this.Recorder.addRecordingEventListener((data) => {
        	console.log('New data!', data.length)
        });

		this.Recorder.start();

Stopping recording:

this.Recorder.stop();
this.Recorder = null;
this.Listener.remove();
this.Listener = null;

Playing the sound (happens after stopRecording() )

let sound = new Player(soundTypeFiles[soundType], {autoDestroy: true});
sound.volume = 0.5;
sound.play(sound.destroy());

The first run of recording returns buffers as expected. The sound plays as expected. However, when I try to record audio again, here is my console:

Start recording
New data!, 0
...nothing
Stop recording
New data!, 0

This is fully functional on android, and I'm not sure what to do on this issue. Any help is appreciated :)

Android audio is noisy

I used your module to record audio on a galaxy S4 device, and exported the audio to a .dat file. I used matlab to play the file, and was surprised to hear how noisy the audio was. Any ideas? Below is my code...
index.js top

import Recording from 'react-native-recording';
import RNFS from 'react-native-fs';
import {testAudioRecording} from './helper';

index.js component

        Recorder = () => {
		this.state.isRecording?console.log('Start recording...'):console.log('Stop recording...');
		this.RecorderTask(this.state.isRecording);
		this.state.isRecording?Recording.start():Recording.stop();
	}
	RecorderTask = (state) => {
		if(state){
			this.recordingdata = [];
			Recording.init({
				bufferSize: 4096,
				//sampleRate: 8000, // for Emulator?
				sampleRate: 44100, // for Actual Device
				bitsPerChannel: 16,
				channelsPerFrame: 1,
			});
			Recording.addRecordingEventListener(datab => this.recordingdata.push(datab));
		}else{
			testAudioRecording(this.recordingdata);
			//Recording.removeRecordingEventListener();
		}
	}

helper.js component

export function testAudioRecording(data){
	const root = RNFS.ExternalStorageDirectoryPath+'/Download';
	//const root = RNFS.DocumentDirectoryPath+'/Download';
		
	const path1 = root+'/recording-test-data.dat';
	RNFS.writeFile(path1, data).then((success) => {
		return true;
	}).catch((err) => {
		return false;
	});



}

Attached below is a sample recording (raw data) of the song 'Give Me Everything' by Pitbull. I had to change the file extension to .txt in order to upload it here.

null is not an object (evaluating 'RNAudioRecord.init')

Hi there,

I am getting this error:

[Unhandled promise rejection: TypeError: null is not an object (evaluating 'Recording.init')]
at node_modules/react-native-recording/lib/index.js:14:30 in default.init
at components/AudioTest.tsx:31:18 in recordSound

In AudioTest.tsx I just have a button that calls recordSound (basically copied from the README):

import Recording from "react-native-recording";

...

async function recordSound() {
  await PermissionsAndroid.requestMultiple([
    PermissionsAndroid.PERMISSIONS.RECORD_AUDIO,
  ]);
  
  Recording.init({
    bufferSize: 4096,
    sampleRate: 44100,
    bitsPerChannel: 16,
    channelsPerFrame: 1,
  });
  
  const listener = Recording.addRecordingEventListener((data) =>
    console.log(data)
  );
  
  Recording.start();
  
  // stop recording
  Recording.stop();
  listener.remove();
}

Can you tell me what I am doing wrong?

I am using expo
on Android
version "react-native-recording": "^0.5.1",

stop()之后，如果再次init()，会出现重复录制的情况

这是第一次init并且start之后的数据
但是当我stop之后，首先，如果不再次init，start是无效的，但是我如果再次init，会出现这样的情况

音频被重复记录了，如果反复这样操作，会继续往上叠加，求助

Error Compiling

To compile this properly, you may have to manually link the module. To do this:
go to android\settings.gradle and add the lines

include ':react-native-recording'
project(':react-native-recording').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-recording/lib/android')

then go to android\app\src\main\java\com\...\MainApplication.java and add the following lines

import cn.qiuxiang.react.recording.RecordingPackage;

as an import statement, and

new RecordingPackage()

under the new MainReactPackage() line in the protected List<ReactPackage> getPackages() { method. Finally, open android\app\build.gradle and add

compile project(':react-native-recording')

inside of dependencies {, then navigate to your project directory and enter cd android && gradlew in cmd (windows).

Hope this helps someone!

One more listener runs and its callback returns always zeros

I ran below code and set listener callback is called every 2.5 seconds. Strangely, two lister callbacks are called and one of which always returns zeros. Does anyone know this situation and solution? I ran android physical device connected to MacOS via USB cable.

import React, {useEffect} from 'react';
import {PermissionsAndroid, Text} from 'react-native';

import Recording from 'react-native-recording';

const App = () => {
  const requestPermission = async () => {
    await PermissionsAndroid.requestMultiple([
      PermissionsAndroid.PERMISSIONS.RECORD_AUDIO,
    ]);
  };
  requestPermission();

  Recording.init({
    bufferSize: 24000 * 2.5,
    sampleRate: 24000,
    bitsPerChannel: 16,
    channelsPerFrame: 1,
  });

  useEffect(() => {
    console.log('start effect');
    const listener = Recording.addRecordingEventListener((data: number[]) => {
      console.log(data.slice(0, 100));

    Recording.start();
    return () => {
      console.log('clean up');
      Recording.stop();
      listener.remove();
    };
  }, []);
