Xiaomi smartphone owners often face the need to quickly change the audio file: cut a fragment from a favorite song to install on a call or remove the extra silence from the voice recorder. Unlike many other manufacturers, Xiaomi builds into their devices powerful multimedia tools that do not require the installation of additional software. However, the functionality of standard applications is not always obvious to beginners, and sometimes the built-in features become insufficient for professional work.
There are several proven methods of editing sound, ranging from the use of a standard voice recorder to specialized audio editors from Google Play. The choice of the specific method depends on what you need to do: just install a ringtone or quality mix tracks. Built-in HyperOS and MIUI system allows you to perform basic operations without loss of quality, which is a huge advantage for the average user.
In this article, we will take a closer look at all the audio trimming options available on Xiaomi smartphones, learn how to work with standard applications, which third-party utilities are worth considering, and which file formats are best used to maintain maximum sound quality, and also touch on the topic of format conversion, as this is often required when installing non-standard ringtones.
Use of the standard Xiaomi voice recorder
The fastest way to crop a recording of a conversation or a lecture is to use the Dictophone app, which is often underestimated as primitive, but in recent versions of MIUI, it has a cropping feature that is hidden in the editing menu. You just have to open the application, find the desired entry in the list and click on it to play.
To start editing, you need to go into editing mode, usually through the "More" button (three dots) or a special pencil icon at the bottom of the screen. Once you select "Edit" or "Prune", you will have a visual wave scale where you can set the boundaries of the cut fragment, and the accuracy of the trimming here depends on the scale, which can be changed with a pinch of two fingers.
⚠️ Note: When you save a cropped recording through a standard voice recorder, the original file can be overwritten or saved as a copy depending on the option selected. Always check for the source before deleting it.
Once the snippet sliders are installed, the system will suggest saving the result. It is important to note that the standard Xiaomi editor is great at.m4a and.mp3 formats, but may have trouble with Lossless formats like FLAC if they were not pre-coded by the system when written.
💡
If a standard recorder doesn't see the right recording, check the application permissions under Settings → Applications → Recorder → Permissions. File access must be allowed.
Cutting through built-in audio player and editor
The second native way that users often ignore is in Xiaomi’s standard Music app. Unlike simple playback, this player has hidden file-sharing functionality. To access it, open any track, click three dots in the corner of the screen, and select “Sound Settings” or “Edit” if available in your firmware version.
The functionality of the built-in editor allows not only to crop tracks, but also to apply simple fading effects (Fade-in/Fade-out), And that's critical to making good ringtones, and that's because the smooth volume increase at the beginning of the call makes it more pleasing to hear, and it doesn't scare you from starting off. MIUI They work fast enough without requiring a powerful processor.
If your version of the shell does not have an editing point, it may mean that the Music Effects component is not installed or disabled, in which case the system will suggest downloading the plugin or using an alternative method. For most regions with global firmware, this functionality is available by default.
☑️ Pre-trimming check
Once the manipulation is complete, the file is saved to the MIUI/Sound folder or to the same directory where the original was, but with the label " cut" or " edited" in the title, making it easy to find the edited track among the many other files in the Manager.
Third-party applications for professional pruning
When built-in tools are not enough, specialized applications from the Google Play Market come to the rescue, the leader in this niche is already the MP3 Cutter and Ringtone Maker application. It is characterized by a minimalist interface and high speed, since it does not require recoding the entire file, but only changes the metadata of the beginning and end of the track.
Another powerful tool is Lexis Audio Editor, which is a full-fledged studio in your pocket that allows you to not only cut, but also to apply effects, noise reduction and change the tone. The app supports multitrack editing, which is rare for mobile platforms. However, for beginners, its interface can seem overloaded.
The third option is a universal combine harvester like Audio Editor & Music Editor, which is convenient because it allows you to set a file on a call immediately after trimming, without wandering through the system settings, which saves time, especially if you need to quickly change the ringtone for a specific contact.
| Annex | Type of editing | Support for formats | Difficulty |
|---|---|---|---|
| MP3 Cutter | Basic pruning | MP3, M4A, WAV | Low. |
| Lexis Audio Editor | Professional | MP3, M4A, WAV, AAC, FLAC | Tall. |
| Ringdroid | Medium (for ringtones) | MP3, M4A, WAV, AMR | Medium |
| WaveEditor | Semi-professional | WAV, MP3, OGG | Medium |
Installation of cropped audio on the call
Once you have successfully trimmed an audio file, it must be properly installed on a call. On Xiaomi, this process has its own peculiarities associated with aggressive system optimization. Simply renaming a file to “ringtone.mp3” may not be enough. It is best to use the standard path: Settings → Sound and vibration → Phone Call.
In the menu that opens, select "Select Melody on Device" (or similar). The system will suggest a File Manager. Find a folder where the cropped track has been saved (usually Music or MIUI/Sound), and select it. If the file is not displayed, it may have an unsupported format or bitrate.
⚠️ Note: To install audio on a contact from a phone book, Contacts must include permission to read the memory.
The alarm clock is set to the notification and the alarm clock, and you have to go directly to the Clock app, select a specific alarm clock, and look for your file at the Sound. The logic of choosing is the same as setting the ringtone, but the path in the menu is different.
💡
Xiaomi system can ignore files DRM-If you cut a track from a streaming service (Spotify, Yandex.Music), it may not be installed on the call due to digital protection of rights.
Work with formats and conversion
The quality of the final audio depends on the original format and bitrate. The standard and most compatible format for ringtones on Android is MP3 or AAC (M4A). The WAV format provides the best lossless quality, but the files weigh significantly more, which can be critical when installing long tunes.
If your cropped file is not playing or the system is writing an error, you may need to convert. Many advanced audio editors have a built-in converter. You can also use online services, but they require a stable Internet connection and consume traffic.
Optimal parameters for ringtones on Xiaomi: bitrate 128-192 kbit / s, sampling frequency 44100 Hz. Higher values (for example, 320 kbit / s) on the smartphone dynamics practically do not give an increase in audible quality, but increase the file size. For voice notes, you can reduce the bitrate to 64 kbit / s.
Why MP3 is better than WAV for ringtones
Frequent problems and their solution
Xiaomi users sometimes face a situation where the cropped file is simply not visible in the list of available tunes. MIUI/HyperOS strictly controls the application's access to the file system, and you must manually allow the editor or dispatcher app to access Music and Audio».
Another common problem is the artifacts of sound at the pruning joints, and if you hear clicks at the beginning or end of the track, it means that the pruning didn't go to the "zero" of the sound wave, and professional editors allow you to see the wave in detail and make a slice at the point where the signal amplitude is minimal, avoiding sharp volume surges.
Also, you should consider that after updating the system, the sound settings may reset, in which case the installation of the ringtone will have to be repeated. Regular backup of the folder with your favorite ringtone to the Xiaomi cloud or Google Drive will help quickly restore personalization.
