How to change the audio playback speed on Xiaomi

Modern Xiaomi smartphones, which are based on the shell MIUI or HyperOS, provide users with huge multimedia opportunities, but some features remain hidden or implemented outside the box. One of these features is changing the speed of audio playback, which is especially important for listening to lectures, audiobooks or podcasts at an accelerated pace. Many device owners face a situation where the standard player does not have an obvious button to adjust the pace, which is puzzling for those who are accustomed to the functionality of desktop programs.

However, there is a solution to the problem of changing the sound speed on Redmi and Poco, and it can be implemented both by the regular system tools and with the help of third-party software that is deeply integrated into the playback process. It is important to understand that Android system limitations sometimes do not allow you to change the pitch (tone height) regardless of speed, but modern sound processing algorithms cope with this quite qualitatively. In this guide, we will discuss all available methods in detail so that you can customize the playback to your needs.

Before we get to the complex settings, it’s worth noting that the effectiveness of one or another method depends on the version of the operating system and the model of your gadget. On new versions of HyperOS, the sound processing algorithms in the Mi Music system player have been significantly revised compared to the older versions of MIUI. So if one of the methods described below does not work, it is worth trying an alternative option, since the architecture of the sound engine may differ.

Standard features of the system player Mi Music

The built-in Mi Music app is the primary tool for listening to tracks on most Xiaomi devices. Developers are constantly updating the interface, and in some versions of the shell, the speed change feature is hidden in the additional equalizer menu or effects. To access these settings, you need to start playing any audio file and open the control panel.

Click on the album cover to turn the player on the full screen, and then look for a three-dot icon or an “Effects” button (often looks like a sound wave or note). The menu that opens should look for “Speed”, “Tempo” or “Learning Mode.” If this option is not explicitly available, try activating the “Smart Sound” or “Mi Sound” mode, where sometimes you hide advanced real-time signal processing options.

Note that the standard Xiaomi player does not always save the speed settings for different files independently of each other. Global setting can be applied to all tracks, which is not always convenient when switching between music and lectures. In addition, at strong acceleration (over 1.5x), artifact sounds can be observed, since the built-in time compression algorithm is not always ideal.

If you have a global firmware version installed in your region, the functionality may be reduced compared to the Chinese version of the CN ROM. Chinese builds often have more advanced audio tools, including detailed playback speed settings that are not ported to the international market due to licensing restrictions or differences in user preferences.

Using Android Hidden Settings for Audio

The Android operating system that underpins MIUI has a hidden layer of settings for developers to interfere with system components, including audio streaming, which is more versatile and independent of the version of the installed player, as it affects the system level of sound processing, but should be used with caution to avoid disrupting the system's work tab.

To activate the developer mode, you need to go to Settings → About Phone and quickly click on the MIUI or HyperOS version seven times. After the notification that you have become a developer, a new section “Additional” or “Extended Settings” will appear in the main settings menu, where you need to select “For Developers”.

• 🔍 Find the item “Windows animation speed” – although it affects the interface, in some builds it correlates with the system media timer.
• ⚙️ Look for the option to “Disable Absolute Volume Level” – this can unlock additional sliders in the audio menu.
• 🎚️ Check for the Audio Effects item in the developer menu for forced activation DSP-processor.

⚠️ Warning: Changing the settings in the Developer Menu may cause the interface to work in an unstable way or conflict with other applications.

There is also a method of activating the hidden test menu through a set of special code in the "caller." Entering code ##64663## (or similar for your model) opens up an engineering menu where you can run a speaker test. Although there is no direct speed adjustment there, resetting the audio profile in this menu sometimes helps if the pace change function was blocked by a software glitch.

Third-party tempo control applications

The most reliable and flexible way to change the playback speed on Xiaomi remains the installation of specialized third-party players. the Google Play application market offers many solutions that can change the speed without distorting the pitch (pitch correction), which is critical for the perception of speech in audiobooks and podcasts.

One of the leaders in this category is VLC for Android, which is completely free and supports almost all file formats, and allows you to change speeds from 0.25x to 4.0x in increments of 0.05, which provides incredible customization accuracy, installing such a player solves the problem of lack of functionality in the standard Music app once and for all.

Another great option is Musicolet, which has no advertising and no internet connection, and has a built-in equalizer and a handy widget for fast speeds from the desktop, and for users who listen to podcasts, specialized clients like Pocket Casts or Google Podcasts, where the speed is implemented at the streaming level, are ideal.

When installing a third-party player on Xiaomi, it is important to adjust the permissions correctly. MIUI is known for its aggressive energy savings, which can kill the background processes of the player, which can interrupt playback, you must manually allow the application to autostart and work in the background in the appropriate battery settings menu.

Setting speed in streaming services

If your audio is not stored in your phone’s memory but is streamed over the Internet, the settings of your Xiaomi device may not take precedence over the settings of the streaming app. Popular services like Spotify, Yandex Music or YouTube have their own playback algorithms that often ignore system commands to change speed.

In the YouTube app, for example, the speed change feature is available directly in the video playback menu (cog icon → Speed). However, for background music, this is not always convenient. Some users use YouTube Music, where this feature is also present. At the same time, Spotify has long not had this feature for music, but implemented it for podcasts, which demonstrates the dependence of the functionality on the type of content.

For services that don't have built-in functionality, there's a system feature on Android that sometimes works. Go to Settings → Accessibility. Find the "Hearing Improvement" or "Audio on a single device." Some versions of Android have a "Replay Speed" slider that forcefully changes the tempo of any sound coming from the phone, including streaming services.

⚠️ Warning: Systemic speed change through special features can distort the sound of system notifications and ringtones, making them too fast or low-frequency.

Problems with codecs and file formats

Often, the inability to change the speed is not due to the lack of function, but to the format of the audio file itself. DRM-files or rare codecs (e.g. older versions) WMA or ALAC in certain containers) may not be supported by the speed change engine.

The solution is to convert the file to a more versatile format, such as MP3 or AAC. On Xiaomi smartphones, you can use converter applications that quickly recode the file without losing audible quality. Once converted, the standard Mi Music player is more likely to recognize the file as editable and allow you to change the speed.

Also worth paying attention to is the bitrate of a file. Too low bitrate (less than 128 kbps) when you speed up playback can lead to strong artifacts and "robotic" sound. Resynthesis algorithms require a certain amount of data to process quality, so high-resolution files (FLAC, WAV) are handled by players better than compressed streams.

Optimize sound through Dolby Atmos equalizer

Many of Xiaomi’s current flagship and mid-range models are equipped with Dolby Atmos technology. It’s not just a marketing ploy, but a powerful audio processing tool that has its own application with advanced settings. In some regions and firmware versions, you can access profiles that affect the dynamics of sound through the Dolby Atmos control panel.

While there is no direct time-stretching in Dolby Atmos, correct frequency balance adjustment can compensate for loss of speech intelligibility when played faster in third-party players. Increased frequencies in the 2 kHz to 4 kHz range helps to better perceive consonants at 1.5x and above.

To activate advanced features, go to Settings → Sound and Vibration → Sound Effects. Select Voice or News profile if available. These presets are speech-optimized and can serve as a great baseline before applying acceleration in the player. The combination of a third-party player with fast speed and system setting Dolby Atmos gives the best result for learning.

The impact of MIUI and HyperOS versions on functionality

Users often notice that some Xiaomi phones have a feature and others don’t. This is directly related to the shell version. In MIUI 12 and MIUI 13, the player’s functionality was limited, while in MIUI 14 and the new HyperOS, the company began to actively implement features to improve productivity, including improved tools for working with audio.

If you’re an older device owner who doesn’t get updates, installing feature updates through the GetApps app (Xiaomi’s app store) can bring a new version of the system player with new functionality. Check the Updates section in the Music app itself, as it updates regardless of the phone’s firmware.

In conclusion, changing the audio speed on Xiaomi is a solvable task, but it requires understanding which tool (system player, third-party app or availability settings) is right for your particular case. The Android ecosystem allows you to flexibly customize your device to your needs, if you know where to look for the right controls.
