Here is an Audio Recorder which can Play and Reverse from your own device microphone.
With this app you can quickly send dim voice message to your friend on social messenger.

It’s super funny and easy to use:
+ Open the app and tap record button to begin recording your voice, a clip of favorite song.
+ Play or Reverse to feel it. You can choose to save into the app to listen to it later.
+ Share to your friend on messages by tapping Share button.

Or you can import an audio to the app and play by going to Menu -> Import Audio File… to decode a given reversed audio.

Please give us a response to make the app better.
