I have tried the Ionic mediaPlugin
import { MediaPlugin } from \'ionic-native\';
var file = new MediaPlugin(\'path/to/file.mp3\');
I\'m still
Check this tutorial first it will guide you. However check this too, it will tell you where you have to store your data.
If you do it on android, you should use externalDataDirectory.
this.filePath = cordova.file.externalDataDirectory;
this.mediaPlugin = new MediaPlugin(this.filePath + this.directoryName + "/" + this.actualAudioFileName);
After this you can find your data under the following folder on your phone Android/data/yourApplicationId/files/yourDirectoryName
