Root Volume Mixer (+Booster) (Unreleased)

Your speaker or headphones* aren't loud enough? (or are too loud)
You want to record gigs or any loud event but your microphone* crackles destroying every audio detail?

Or you have to shout during calls because microphones* aren't sensitive enough?

In any of these cases, this app may be exactly what you search for.

*features of pro version, the free lets you tweak speaker only.


**I'm not responsible of any damage made to your device or your ears, tweak values progressively**
***The app works by editing a system file that is different between devices, so every device can have different results, and some values may not show up if not detected in the system file. I am always available to refund, contact me by e-mail in that case***
