Sound Regulator

Have not you thought liking to adjust volume finely?
It is this application to you!
If it is this application, rough regulation by a button cannot be carried out, but it can adjust finely so that he can be satisfied.
Things set up individually, such as system volume and musical volume, are possible.
* An effect is not among the applications which a volume setup has been independent of in part.
