How to set up an equalizer on bass on Android Xiaomi: Instructions

Modern Xiaomi, Redmi and Poco smartphones often feature high-quality multimedia speakers, but standard audio settings may not satisfy demanding users, especially those who love high-power low frequencies. Many device owners face a situation where listening to music or watching movies lacks depth and saturation of sound. Fortunately, the MIUI operating system and its successor HyperOS provide extensive tools for fine calibrating the audio stream.

In this article, we will take a closer look at all the available ways to amplify basses, from built-in system functions to advanced methods using third-party software. You will learn how to properly activate Dolby Atmos, adjust the graphical equalizer and avoid common errors that can lead to speaker wheezing.

Before we make any changes, it’s worth noting that the quality of playback depends not only on the software settings, but also on the hardware capabilities of a particular smartphone. Budget models can have physical limitations on the amplitude of the speaker membrane, so excessive amplification of low frequencies can lead to distortions. However, proper frequency spectrum balancing can significantly improve the perception of audio even on the initial devices of the line.

Built-in MIUI and HyperOS sound panel tools

The first step in improving sound should be to use native shell capabilities. In Xiaomi smartphones, the Sound Effects component is responsible for this, which is integrated directly into the system settings. To get into the control menu, you need to go through the Settings → Sound and Vibration → Sound Effects. Here the user finds a basic sound improvement switch that often works automatically, but can be activated manually to force the application of processing algorithms.

Inside this menu, a key tool is a graphical equalizer, which is a set of sliders that correspond to certain frequency ranges. To amplify bass, we're interested in left sliders, usually labeled 60 Hz, 150 Hz or 400 Hz. By raising their values, you add "body" and humminess to sound. But it's important to observe the measure, because the sharp rise of these frequencies without compensating for the averages can make sound cloudy and unintelligible.

The system also offers presets developed by the company's engineers for different genres of music. The choice of a Rock, Pop or Bas-Buss profile instantly applies a predefined equalization curve. It's a convenient option for those who don't want to spend time manually adjusting parameters. It's worth experimenting with each profile on your favorite track to see which algorithm best fits the acoustic features of your phone model.

⚠️ Attention: When lifting the equalizer sliders above +4 dB or +6 dB on budget models of smartphones can be observed the effect of clipping (digital overflow), manifested in the form of unpleasant wheezing and coding on loud areas of the composition.

To get deeper into the settings, you can use the hidden functions of the engineering menu, although access to them is limited in new firmware versions. The standard path through the audio settings is the safest and most stable way to modify the audio stream. Remember that the changes take effect immediately, allowing you to evaluate the result in real time.

Activation and configuration of Dolby Atmos on Xiaomi

Dolby Atmos is a surround sound standard that creates a three-dimensional audio-space effect. On Xiaomi devices, this feature is often hidden or only available in certain regions, but its activation can dramatically change the sound. Atmos not only amplifies the bass, but intelligently distributes frequencies, adding depth and clarity. To enable you need to find the appropriate item in the audio effects menu or use the MI Sound app depending on the shell version.

Once the technology is activated, the user is given a choice of profiles such as Auto, Film, Music and Voice. To maximize the impact on low frequencies, it is recommended to choose Music or Film mode, where algorithmic processing is aimed at expanding the dynamic range. In Auto mode, the system itself analyzes the content and applies the desired filters, which sometimes leads to a less pronounced bass response compared to manual selection.

It's important to understand the difference between a simple equalizer and a Dolby spatial processing. If the equalizer mechanically raises the volume of certain hertz, Atmos works with psychoacoustics, creating the illusion of more powerful sound without critically increasing the load on the speaker, this is especially true for compact smartphone housings where the physical size of the emitter is limited.

It’s worth noting that Dolby Atmos requires additional processing power, and on older smartphone models, enabling this feature in combination with heavy gaming or multitasking can theoretically lead to micro-twitching of the interface, although on modern Snapdragon and Dimensity chipsets, this impact is minimized.

Use of third-party equalizer applications

If built-in tools are not enough, Google Play Market apps come to the rescue, with leaders in this niche being Poweramp Equalizer, Bass Booster, and Flat Equalizer, which intercept audio before it is sent to the speaker and use their own processing algorithms. Poweramp, for example, is famous for its high-quality play engine and flexible frequency band configuration.

When installing a third-party equalizer, it is critical to provide the application with the necessary permissions. In modern versions of Android (10, 11, 12 and above), the system strictly controls access to the microphone and modification of system settings. Without permission to Change System Settings or Access to Use, the application will not be able to correctly process sound from other sources such as YouTube, Spotify or VK Music.

Many users mistakenly believe that installing a booster will automatically make the sound better. In fact, misuse of such programs can lead to poor quality. Aggressively amplifying low frequencies in a third-party application on top of already processed system sound often causes severe distortions. It is recommended to first reset the system equalizer settings to zero before starting third-party software.

The Wavelet app, which uses an autocorrect database for specific headphone and speaker models, can automatically apply the optimal profile for your device if it is in the database, and is a great example of how software can compensate for hardware flaws.

Set-up Developer Parameters for Audio

In the depth of Android settings, there's a developer menu that contains hidden audio controls, and you have to click on the build number several times in the About phone section to get there. Among the many technical options, we're interested in absolute volume and volume limits.

One useful feature is to turn off Absolute Volume. In standard Android mode, it synchronizes the volume of the phone and the connected Bluetooth device. Disabling this feature allows you to adjust the volume of the smartphone speaker and headphones independently, which can help squeeze additional decibels out of the system if one of the channels was limited by software.

Also on the developer menu, you can find the option Disable Absolute Volume, which sometimes solves problems with quiet sound on Bluetooth headsets, but can also be useful for internal acoustics in some audio stream scenarios. However, be careful: changing these settings can lead to the fact that when you connect external devices, the sound will either be too quiet or, conversely, deafeningly loud from the beginning.

Some enthusiasts resort to editing system files through root rights, changing the parameters of the mixer. mixer_paths.xml. This allows you to directly control (amplify) digital amplifiers. However, this procedure is extremely dangerous for beginners and can lead to someone damaging the speakers or software failure of the system, so in this article we will not give specific commands for editing system files.

⚠️ Note: Experiments in the Developer menu can lead to unstable Bluetooth connections or conflicts with system applications. Write down any changes you make so you can return settings back.

Compatibility issues and hardware limitations

You can't ignore the fact that software setup has limits dictated by hardware. Xiaomi's entry-level and mid-range smartphones often use monophone speakers or stereo pairs with asymmetrical sound (the main speaker at the bottom and the conversational speaker at the top).

Excessive software processing of the signal on weak speakers leads to mechanical wear. The speaker membrane oscillates with a greater amplitude than the design provides, which leads to its stretching or coil break. If you hear a constant cracking even after resetting the equalizer settings, this may indicate that the speaker has begun to physically destroy.

In addition, you should consider the codecs used in the transmission of sound. When listening to music via Bluetooth, it is important that both the smartphone and the headphones support high-quality codecs like aptX HD, LDAC or at least aptX. The standard SBC codec has a low bitrate, and any attempts to amplify the bass on such a compressed signal will only emphasize the artifacts of compression, making the sound “porridge”.

Owners of devices with a 3.5 mm connector (which is becoming less and less in the Xiaomi line) should be aware of the resistance of the headphones. the built-in smartphone amplifier may not cope with low-omnipotent load at maximum amplification of the bass, which will overheat the audio chip and automatically reduce the volume to protect the circuit.

💡

Use high-quality audio files (FLAC, WAV) to adjust the equalizer. Compressed formats like MP3 with a low bitrate (less than 192 kbps) with amplified bass sound significantly worse due to the loss of frequency spectrum.

FAQ: Frequently Asked Questions

💡

Optimal sound tuning is a balance between the desired power of the bass and keeping the intelligibility of the medium frequencies. Don't try to twist all the sliders to the maximum, it's better to find the "middle ground" for your acoustic system.
