OK GROW FORK:

This fork adds ability to also record from Bluetooth as well.

Here's how you can use it:

t path = `${AudioUtils.DocumentDirectoryPath}/file.aac`;

t inputs = await AudioRecorder.getAvailableInputs();

ole.log(inputs);

(let input of inputs) {
 (/LOTUS/.test(input.name)) {
await AudioRecorder.prepareRecordingAtPath(path, {
  preferredInput: input.id,
  // ... other options such as sample rate, etc.
});

The AudioRecorder.getAvailableInputs() returns a list of available recording devices like this:

id: 'Built-In Microphone',
type: 'builtInMic',
name: 'iPhone Microphone' },
id: 'D4:F5:11:50:8A:22',
type: 'bluetoothHFP',
name: 'LOTUS 1.7-12311' } ]

Original Readme:

Record audio in iOS or Android React Native apps.

BREAKING CHANGES

For React Native >= 0.40, use v3.1.0 and up. For React Native <= 0.39, use v3.0.0 or lower.

v3.x removed playback support in favor of using more mature libraries like react-native-sound. If you need to play from the network, please submit a PR to that project or try react-native-video.

Installation

Install the npm package and link it to your project:

install react-native-audio --save
t-native link react-native-audio

On iOS you need to add a usage description to Info.plist:

>NSMicrophoneUsageDescription</key>
ing>This sample uses the microphone to record your speech and convert it to text.</string>

On Android you need to add a permission to AndroidManifest.xml:

s-permission android:name="android.permission.RECORD_AUDIO" />

Manual Installation on Android

This is not necessary if you have used react-native link

Edit android/settings.gradle to declare the project directory:

ude ':react-native-audio'
ect(':react-native-audio').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-audio/android')

Edit android/app/build.gradle to declare the project dependency:

ndencies {
.
mpile project(':react-native-audio')

Edit android/app/src/main/java/.../MainApplication.java to register the native module:

rt com.rnim.rn.audio.ReactNativeAudioPackage; // <-- New


ic class MainApplication extends Application implements ReactApplication {
.
verride
otected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
    new MainReactPackage(),
    new ReactNativeAudioPackage() // <-- New
);

Running the Sample App

In the AudioExample directory:

install
t-native run-ios
t-native run-android

Usage

To record in AAC format, at 22050 KHz in low quality mono:

rt {AudioRecorder, AudioUtils} from 'react-native-audio';
audioPath = AudioUtils.DocumentDirectoryPath + '/test.aac';

oRecorder.prepareRecordingAtPath(audioPath, {
mpleRate: 22050,
annels: 1,
dioQuality: "Low",
dioEncoding: "aac"

Cross-platform options

leRate: int
nels: int
oQuality: string
oEncoding: string

Encodings supported on iOS: lpcm, ima4, aac, MAC3, MAC6, ulaw, alaw, mp1, mp2, alac, amr Encodings supported on Android: aac, aac_eld, amr_nb, amr_wb, he_aac, vorbis

iOS-only fields

The MeteringEnabled boolean to enable audio metering.

Android-only fields

AudioEncodingBitRate: int OutputFormat: string, mpeg_4, aac_adts, amr_nb, amr_wb, three_gpp, webm

See the example for more details. For playing audio check out React Native Sound

MP3 recording is not supported since the underlying platforms do not support it.
