About Audio Recorder Android App

This application allows you to record audio using your phone's microphone

Now you can cut the recording, modify the volume and remove the background noise!

To organize your recordings, you can mark them as favorites or apply a label.

* Favorites: lists all the recordings that have the favorite mark.
* Labels: the application allows you to create labels, with a name and a color, and to label the recordings. This way we can organize the recordings and find them faster. The labels can be ordered by holding the label, dragging and dropping it in the desired position.
