Audio DSP & EQ Plugin
Audio DSP & EQ Plugin free mobile software is an equalizer for devices with Android OS. This application will allow you to fine-tune your music on your device. Adjustment is made by movement of the sliders, the higher the slider, the greater frequency will be played.
The application interface is made in bright colors, and will not cause problems with understanding. If set too high values for low frequencies, it is unlikely that your speaker will not be able to play at that level, so you need to reduce, rather than refer to the fact that the application "performs bad".
