On ROG Phone and other ASUS smartphones, there's a feature called AudioWizard. You can find it by following this path:
Settings => Sound & Vibration => AudioWizard
You will then see a screen that looks like this:
In simple terms, this feature works by adjusting specific frequency bands to change the way we hear sound, giving us a different auditory experience.
Let’s temporarily skip the top section labeled “Scenario Effects” and first explain how the equalizer works.
What Is an Equalizer?
You’ve probably seen an equalizer before—those vertical sliders within AudioWizard—but may not fully understand how it functions.
Let’s break it down simply:
The sliders are used to adjust the volume of specific frequency ranges.
When we adjust the phone’s general volume, it’s like moving all the sliders at once. But the equalizer lets us control the volume of specific “ranges” of sound individually. This is a common tool in audio recording. When we listen to music or songs, the recorded audio has usually been finely tuned by professionals using equalizers and mixing techniques so that we hear the exact “feeling” the creator intended.
That might still sound abstract, so let’s use an example. Consider a movie scene that includes sound effects, music, and dialogue—like this one:

In this clip, you can hear a variety of sounds. When characters speak, the background music builds gradually but never overpowers the dialogue because its volume has been intentionally reduced. When the character pilots the spacecraft, even though the camera stays on their face, we can clearly hear the control stick and button sounds. When the ship begins to move, the bass becomes heavier—the “boom! boom! boom!” drumbeat strengthens the rhythm and builds tension.
All of this is the result of audio mixing. Of course, actual post-production is often more complex and nuanced. In editing software, not only are equalizers used, but also multiple adjustable audio tracks. Still, it comes down to adjusting the volume of different sound elements.
Most of the audio we hear through our phones has already been edited using equalizers, but we can also use our own equalizer to manually boost or reduce certain frequency ranges for different effects. There’s no right or wrong here—just personal preference.
Once we understand how an equalizer works, the “Scenario Effects” feature becomes easier to grasp—it simply applies preset equalizer settings to produce different sound effects.
So, How Do You Use an Equalizer?
To emphasize again: there is no single correct way to adjust sound. Whether something sounds good or bad is entirely personal and subjective. But because ROG Phone gives us detailed control over these settings—allowing us to shape the audio output from both speakers and headphones—we’re free to tweak things however we like. Try listening to the same piece of audio before and after making changes to notice the difference. Discover what “feeling” you can bring out.
For beginners, you can start with the simplest controls at the bottom: “Treble” and “Bass.” For example, if you want music to sound more rhythmic, try increasing the bass. If you want vocals in a song to stand out more, try boosting the treble.
The ten equalizer sliders each correspond to a specific range of frequencies (though adjusting one frequency usually affects nearby ones, as neighboring frequencies tend to interact). In my opinion, the biggest drawback of AudioWizard’s interface is that while it shows an animated soundwave at the top during playback, it doesn’t display a frequency spectrum graph, which would help users visually understand the impact of their adjustments. As a result, it's hard to clearly see how changes to specific frequencies affect the overall audio spectrum.
Still, this isn’t professional-grade mixing software. We don’t need to overanalyze it—just have fun experimenting with the sliders and enjoy the different effects they can create!
