Speaker Booster Sound Booster for Android
Speaker Booster Sound Booster from other similar applications is that when a user activates boost this app not only amplifies the sound to the end, but also uses the built-in Android equalizer to optimize the frequency channels by means of a special algorithm. So the result is a stronger and clearer sound.
