Equalizer is a powerful audio equalizer with a very simple user interface and five-band volume slider. It allows you to adjust the sound effect levels so that you get the best sound from your music player or audio player.

You can also apply the Equalizer Presets based on the genre of the music or create your own with the five-band equalizer controller. You can save the custom presets or create new ones with the media volume control.

If you want to add more effects to the sound, you can turn them on. These include the Virtualizer, the Bass Booster, and the Reverb.
