A complete control panel for your Android audio
This application allows you to adjust the sound for each and every situation in which you may be affected. We are not only talking about the volume, if it is activated, or in silence mode, but also about who decides on it. That is, you can establish custom settings or allow, in each case, applications to decide how to manage it.
With the app you can control audio from aspects such as:
Playing media files.
Devices connected by wire, Wi-Fi or Bluetooth.
You will be able to configure each of these aspects, defining personalized tones, patterns of behavior ... remembering that this is a test that lasts 2 days, but if you want to enjoy all the functions you will have to give up.
