ngCordova media record audio

.Hi, I'm trying to get audio recording to work in ngCordova.

I'm running this on an Android 4.4, and the debugger is showing successes and no failures.

I can't find the files in ES File Explorer (any suggestions for tools)?

I'm familiar with Angular, but not mobile dev. .play() does not play the file back. I found a temp file on my phone with my recorded voice.

Why isn't this working? Is there a demo app somewhere? Thanks!

'use strict';

angular.module('app')
.controller('StaticController', function($scope, $ionicPlatform, $cordovaFile, Audio) {


  $scope.suggestion = "Hello World";

  $scope.slug = "HelloWord.amr";

  $ionicPlatform.ready(function() {
    $scope.audioFile = $cordovaMedia.newMedia(Audio.getFilePath($scope.slug));
  });

  $scope.isRecording = false;

   // WRITE
  $scope.writeFile = function() {
    $cordovaFile.writeFile(cordova.file.dataDirectory, "file.txt", "text", true)
    .then(function (success) {
      console.log('success');
      console.log(success);
    }, function (error) {
      console.log('error');
      console.log(error);
    });
  };

  $scope.play = function() {
    $scope.audioFile.play();
    console.log('play');
  };

  $scope.startRecord = function() {
    $scope.isRecording = true;
    $scope.audioFile.startRecord();
    console.log('startRecord');
  };

  $scope.stopRecord = function() {
    $scope.isRecording = false;
    $scope.audioFile.stopRecord();
    $scope.audioFile = $cordovaMedia.newMedia(Audio.getFilePath($scope.slug));
    console.log('stopRecord');
  };

});
