react-native-audio-4expo

React Native Sound Audio AudioPlayer AudioRecorder No Linking

This package provide audio recorder and player components that you can drop into your application. It does not require linking to native code, so it is suitable for React Native applications built using Expo.

This package replaces and expands on the react-native-sound-recorder-no-native package.

This module makes extensive use of the Expo.io Audio SDK located here. It includes a sensible set of audio setup defaults, but can be customized using the information contained in the expo.io documentation.

Why Use This?

This module is useful if you need drop in sound recorder or player components for an application in which using platform specific native code is prohibited; for example an application created using expo.io.

Why Not Use This?

You are not restricted from using native code, and can find a better module to use.

Installation

npm install --save react-native-audio-4expo

Usage

import {AudioRecorder, AudioPlayer} from 'react-native-audio-4expo';

Customize the UI

The Record and Play buttons badges can be customized by altering the package's GetRecordButtonByStatus and GetPlayButtonByStatus files. Both of these files return default components displayed by the AudioRecorder and AudioPlayer components, respectively. The default UI components make use of the UI Kitten library for buttons and FontAwesome for icons.
