Owners of Xiaomi, Redmi and POCO smartphones often face the need to quickly change the duration of an audio file. Whether it is creating a ringtone, cropping a voice message or preparing a track for video editing, the built-in capabilities of the system are not always obvious. Fortunately, the MIUI and HyperOS shells provide tools to solve the problem without installing third-party software, although third-party applications are often more powerful.
There are several proven methods that work consistently on most modern models. Cutting audio may be necessary to save memory space or to personalize the device. We will look at all the current ways, from the system recorder to specialized applications from Google Play, which allow you to work with MP3, M4A and WAV formats.
It is important to understand that the quality of the source file directly affects the result. If you are working with a high-resolution track, make sure that the method you choose does not compress it further. Next, we will discuss each method in detail so that you can choose the most convenient for your situation and smartphone model.
Using the Xiaomi system voice recorder
Many users are unaware that the standard Dictophone app in Xiaomi smartphones has built-in functionality for editing records. This is the fastest way to crop audio if the original file was written on the device itself or imported into the record folder.
To get started, open the app and select the entry you want from the list. The interface here is minimalistic but functional. Click three dots in the corner or the menu button to find the edit option. The system will prompt you to select the beginning and end of the snippet you want to save.
Once the sliders are installed, you need to save the result. Note that the recorder may suggest that you save the file as new so as not to damage the original. This is a reasonable practice to avoid accidental loss of important data.
The Secret Function of the Recorder
Online services for quick pruning without installation
If you don't want to clog up your memory with apps, online services are a great solution. Browsers like Chrome or MI Browser can easily handle server-side audio processing, which is especially useful when you need to quickly make a ringtone on someone else's phone or in a guest akka.
One of the most popular tools is AudioCutter, which supports downloading files from the cloud or from the phone's memory, and it's simple: you download a track, slide the right segment, and you download the result, the processing quality remains high, and the encoding is automatic.
The advantage of web tools is that they're cross-platform, and it doesn't matter what version of Android or MIUI you have, the site will open and work, but you have to be mindful of the traffic costs if you don't have Wi-Fi.
- 🎵 Support for all popular formats: MP3, WAV, OGG
- 🌐 No requirement to install or obtain permits
- ⚡ Instant results without complex processing
- 📱 Adaptive interface for mobile screens
⚠️ Note: When using online services, do not download sensitive records or files containing personal information, as they are processed on third-party servers.
Top Apps from Google Play for Editing
For those who plan to create ringtones or process sound regularly, it is better to install a specialized application. MP3 Cutter and Ringtone Maker is the market leader. It provides accuracy up to a millisecond and allows you to make smooth attenuation.
Another powerful tool is the Lexis Audio Editor, which is almost a professional tool in your pocket, and you can not only cut, but you can also apply effects, change speed and normalize volume. For simple tasks, it may seem complicated, but the functionality is worth it.
When installing these programs, carefully read permission requests. Often they require access to all files on the device. In modern versions of Android, this is a necessary step to work with the media library, but it is better to use proven applications with high ratings.
Installing third-party software gives you complete control of the process, so you can create exact copies of fragments, glue multiple tracks, and even convert formats on the fly, which turns a smartphone into a full-fledged mobile studio.
Creating a ringtone through system settings
The unique feature of the MIUI and HyperOS shell is the ability to configure the ringtone directly into the sound menu using the built-in editor. You don't have to pre-prepared the file. Just select any track from your library as a call signal.
Go to Settings → Sound and Vibration → Phone Rington. From the list that opens, select “Select Music” or click on the plus icon. The system will open a player where you can select a song. After selecting a track, click the edit button (usually looks like scissors or sliders).
Here you can select a specific clip of up to 30-40 seconds that will play back when you call in, and it’s the perfect way to personalize your contacts without creating unnecessary copy files in your device’s memory.
☑️ Checking before installing the ringtone
Comparison of popular processing methods
To make it easier for you to choose the right way, we have compiled a comparison table that will help you understand which tool is best for your goals: quick editing or deep editing.
| Method | Difficulty | Quality. | We need the Internet. |
|---|---|---|---|
| Dictaphone | Low. | Average. | No. |
| Online services | Low. | High. | Yes. |
| Specialist annexes | Medium | Maximum. | No. |
| MIUI settings | Low. | High. | No. |
As you can see from the table, online services or system settings are best for one-off tasks, and if you plan to work with sound often, it's worth spending time learning a full-fledged editor.
💡
To maintain the maximum quality of the source track, always choose methods that work offline (applications or system tools), as they do not compress the file again when you download.
Working with formats and preserving results
When cutting music, it is critical to understand the difference between formats: MP3 format is compressed and most compatible; WAV format stores lossless sound but takes up 5-10 times more space; while saving the ringtone for Xiaomi, it is better to use MP3 or M4A.
Some applications can automatically change bitrate when saved. If quality is important to you, check your export settings. Usually the optimal value is 192 kbit / s or 320 kbit /. Smaller values can make the sound "flat".
When you save a file, make sure you check where it is. Usually, apps create a folder called AudioCutter or RingtoneMaker at the root of the internal memory, and sometimes you need to manually specify the path to it through the file manager to install a file on a call.
⚠️ Note: When converting from lossless formats (FLAC, WAV) into MP3 There is an irreversible loss of quality. Always save the original file.
