react-native-audio-record

Audio record buffers for iOS and Android.

Install

``
yarn add react-native-audio-record
react-native link react-native-audio-record
`

Usage

`js
import AudioRecord from 'react-native-audio-record';

const options = {
sampleRate: 16000, // default 44100
channels: 1, // 1 or 2, default 1
bitsPerSample: 16, // 8 or 16, default 16
audioSource: 6, // android only (see below)
wavFile: 'test.wav' // default 'audio.wav'
};

AudioRecord.init(options);

AudioRecord.start();

AudioRecord.stop();
// or to get the wav file path
audioFile = await AudioRecord.stop();

AudioRecord.on('data', data => {
// base64-encoded audio data chunks
});
`

For audioSource use one of the constant values from here. Default value is 6 (VOICE_RECOGNITION).

Use 3rd-party module like buffer to decode base64 data. Example -
`js
// yarn add buffer
import { Buffer } from 'buffer';
chunk = Buffer.from(data, 'base64');
`
Don't forget to add microphone permission in your app.
