ExtraVolumeSimple(Fine-tuning)

This app is a simplified version of ExtraVolumeConfig. It is an application to play an active part if you want to do is fine-tune the volume! It is too big to too small If you lower one, and I on one! I create a simulated volume that does not exist originally. You can also be used on non-root terminal! It will be reflected in the sound all that out of the terminal.
