Extra Volume Booster is an app that lets you control the volume of your Android smartphone by increasing it to levels that are not usually within range. You can also use this app to equalize the sound according to your preferences.
The way Extra Volume Booster works is very simple. It has two main volume control buttons: a wheel for raising and lowering the volume of your smartphone as you would normally (similar to your smartphone’s side buttons), and a bar for the speakers, which lets you increase your smartphone’s overall sound. There are also several buttons for muting the sound, resetting the volume (by removing the boost), and maxing it out (with the boost at its maximum level), the levels of which are all indicated with percentages.
You can also use Extra Volume Booster to equalize the sound with presets or custom settings. After that, all you have to do is play a song on a music player app, such as Spotify, then use Extra Volume Booster to equalize the sound or increase the volume.
Extra Volume Booster is a great tool that gives you greater control of your smartphone’s volume, letting you increase it above its usual limits. You can also play around with the equalization until you get a sound you like.
