This app is a useful tool for people who want to make a recording of their own. The only thing you need to do is to select the audio or video file you want to record, press the record button and wait for it to finish. Once it's done, you can save the file and you're ready to share it with your friends.

To make it more interesting, you can add some noise to the file and then try to remove it. It's a good idea to use this app to improve the quality of your recordings.
