The application allows you to download and listen to audio files directly from the website, in this case, the application is used as a plug-in for the website called Smule.

The way it works is that when you download the application, it will automatically start downloading the audio file to your device, so you don't have to do anything else.

When you open the application, you will see a list of all the files that you have downloaded so far, so you can easily select the one you want to listen to.

After that, you can click on the play button to start listening to your file.

Note: Don't download more than one audio file at a time, or else the server may consider it as an illegal activity.
