Personalizing a smartphone is not just about changing wallpaper, it's about creating a unique experience with the device. When you pick up the Xiaomi Redmi 9, the first thing that gives off its personality is often the melody of the call. Standard ringtones pre-installed by the manufacturer can be boring or too intrusive, so many users tend to replace them with their favorite tracks. However, simply downloading a file is not enough: often the composition is too long, contains unnecessary introductions or does not have the necessary accent at the beginning.
The process of creating a ringtone based on the Android operating system requires some preparation of an audio file. You need not only to choose a track, but also to edit it correctly, removing extra seconds and adjusting the volume. In this article, we will discuss all the available ways to crop a song on Android for a Xiaomi Redmi 9 call using both built-in tools and third-party software. Competent cropping will avoid awkward pauses before the beeps and ensure instant recognition of the incoming call.
Owners of Redmi devices with a MIUI shell face a number of features when installing their tunes. The system has strict restrictions on access to system files and requires certain actions to activate user audio. We will look at an algorithm of actions that is guaranteed to work on current versions of firmware, and help you avoid common mistakes. Properly tuned sound is a guarantee that you will never miss an important conversation in a noisy environment.
Preparation of audio file and choice of format
Before you start editing, you need to make sure that the source file meets the technical requirements of the system. Android and the MIUI shell work best with the MP3 format, which provides good sound quality with a relatively small file size. Although the system can play WAV or OGG, using MP3 ensures maximum compatibility and no errors when trying to install a track on a contact or SIM card.
The track bitrate is an important parameter. The ringtone does not require studio quality, so the best choice is 128 kbit / s or 192 kbit / s. Higher values, such as 320 kbit / s, will only increase the file size without a noticeable benefit to the speaker of the smartphone. In addition, too "heavy" files can be loaded into the audio buffer longer, which will delay the start of playback in the first seconds of the call.
⚠️ Note: Do not attempt to install ringtone files with DRM-protection (for example, tracks from streaming services with limited copying). Xiaomi Redmi 9 will not be able to play them as system sound, and you will see an error when selecting a file in the settings.
Also worth paying attention to the structure of the file. If you plan to use an embedded editor, make sure that the file is saved in an accessible folder, such as the Music root directory or Downloads. The Android file system is sensitive to paths, and if the track lies deep in the archives of messengers, the search can take a long time.
💡
For best results, choose tracks where the vocals or the main motif start immediately, without long instrumental introductions, which will allow Caller to hear the music from the first second.
Using the built-in editor Xiaomi
Many users do not know that Xiaomi Redmi 9 already preinstalled a functional tool for working with audio. the Dictator app or the standard player Music often have basic trimming functions that allow you to quickly create a ringtone without installing additional software. This is ideal for those who want to keep the system clean and not clog up memory with unnecessary programs.
To use this method, open the track in a standard player. In the playback control menu (usually three dots or a gear), find "Create a ringtone" or "Turn it off." The interface will ask you to select the starting and end points of the segment with an accuracy of milliseconds. The visual wave chart helps you pinpoint the moments where the music begins and where it dies down.
- 🎵 Open the Music app and select the track from the list.
- ✂️ Click on the menu (three dots) and select the "Create a ringtone" option".
- 📍 Move the sliders to highlight the fragment lasting up to 30-40 seconds.
- 💾 Click Save, the system will automatically assign the file a name and save it.
Once saved, the file automatically enters the appropriate ringtone system folder, which means you don't have to manually search for it in the audio settings - it will immediately appear in the list of available tunes. However, the functionality of the built-in editor can be limited: it does not allow you to apply fade-in/fade-out effects or change the volume, which is sometimes critical for sharp compositions.
Third-party music cropping apps
If built-in capabilities aren’t enough, Google Play Market offers a huge number of specialized applications, led by MP3 Cutter and Ringtone Maker and Ringdroid, which provide advanced functionality including precision cropping, mixing tracks, changing playback speeds, and applying audio effects.
When installing third-party software on Xiaomi Redmi 9, pay attention to the permissions requested. The audio application requires storage access (“Files and Media”). Without this, it will not be able to read the source file or save the result. Be careful with applications that require access to contacts or locations without an explicit need – this can be a sign of data collection.
Consider the algorithm of work on the example of the popular MP3 Cutter:
- Launch the application and give access to the files.
- Select a track from a list sorted by folders or artists.
- Use your fingers to zoom in (waveform) and highlight the area accurately.
- Apply the effects if necessary and press the save button.
⚠️ Attention: Many free apps contain aggressive ads. When cropping a song, carefully monitor where you click so that you don't accidentally download an ad. APK-file instead of saving the result. Use only proven programs with high ratings.
The advantage of third-party applications is that they can be batched, you can slice multiple tracks for different contacts or SIM cards at once, and they often allow you to save files in different formats and with different compression quality, which gives you more flexibility. For Android, this is standard practice, since standard tools manufacturers are often stripped down.

Online services for quick pruning
When you don't want to install new apps, online services come to the rescue. Sites like mp3cut.net or audiocutter.com let you do all the work right in your Chrome browser or MI Browser, which is especially convenient if you need to quickly trim a single file, and you don't want to clog your smartphone memory with temporary programs.
The process is simple: you upload a file to a server, process it with the site and download the finished result. The main requirement is a stable Internet connection. The processing speed depends on your data plan and the quality of communication. For owners of Redmi 9 with 4G support, this is usually not a problem, but it is worth remembering the traffic consumption.
| Parameter | Built-in editor | Annex | Online service |
|---|---|---|---|
| We need the Internet. | No. | No (usually) | Yes (required) |
| Pruning quality | Basic | High. | High. |
| Advertising | No. | Often | Many. |
| Difficulty | Low. | Medium | Low. |
The main advantage of the online method is cross-platform. You can start cropping on your phone, and if the interface is uncomfortable, continue on your computer by logging into the browser history (if the service saves a session) or simply by flipping a file. However, by uploading personal audio files to third-party servers, you theoretically risk privacy, although for ordinary music tracks this is rarely a problem.

Installation of a cropped melody on a call
Once the file is ready, it needs to be installed correctly. In the MIUI shell, this process has its nuances. Simply renaming the file is not enough; the system must "see" it in the correct directory or select it through settings. If you used the built-in editor, the file is already there. If a third-party, check the way you save it.
To install, go to Settings → Sound and Vibration → Rington. Here you will see a list of standard tunes. Scroll down or up to the "Select Rington from Files" button (plus icon or folder icon) and the file manager will open to find your cropped track. Once selected, it will automatically stand up for the call.
Special attention should be paid to the installation of a ringtone on a specific contact. Xiaomi Redmi 9 does this through the application "Contacts":
- 👤 Open the contact you want to assign a unique sound to.
- ⚙️ Click "More" or select "Sound" in the contact card.
- 🔊 Select “Your ringtone” and find your file in the list.
- ✅ Save the changes, now this subscriber will call uniquely.
⚠️ Note: If you use two of these SIM-And remember to set the melody for each of these cards separately. By default, the system can only apply the settings for the first SIM, and you can't tell the difference between calls to different numbers.
In some cases, after updating the system, the sound settings may get lost. So it makes sense to save the source files of cropped tracks in the cloud or on the computer. Also remember that when cleaning the cache, "some" applications can delete their temporary files, so store the finished ringtones in a reliable folder, such as Ringtones in the root of internal memory.
💡
Files saved to the Ringtones folder in internal memory automatically appear in the system ringtones list after the smartphone is rebooted.
Solving problems and mistakes
Even when following the instructions, Redmi 9 users may encounter difficulties. One of the common problems is that the file is cropped, saved, but not in the ringtones list. Most often it is because the file is in the wrong folder or has an unsupported bitrate. Try moving the file to the root of the Ringtones folder and restarting the device.
Another problem is quiet sound or wheezing, which can be caused by the source file being too loud (clipping) and the smartphone speakers not being able to handle volume peaks when converting, and in such cases, normalizing the volume in the editor before saving helps, and making sure that peak values don't go to the red zone.
Users also complain that the ringtone is reset to the standard one after rebooting. This often happens if the file has been deleted or moved. Android doesn't like system links to lead nowhere. Always store ringtone files in internal memory, not on the back of the system. SD-map, as the card can be mounted later than the system load, and the sound simply does not have time to load.
If nothing works, try clearing the Themes or Sounds app cache in the application settings. Sometimes the system glitch keeps the list of available audio files from being updated. At the very least, third-party call management apps can take over, ignoring system limitations.
