How to Cut a Recording Recording on Xiaomi: A Step-by-Step Guide

Xiaomi, Redmi and POCO smartphone owners often use a built-in voice recorder to record lectures, interviews or important conversations. However, the standard recording feature is not always perfect: there may be unnecessary noises, pauses or extraneous conversations at the beginning or end of a file. There is a natural need to quickly remove these fragments without rewriting the entire file. Fortunately, the MIUI shell and the new HyperOS provide a basic but functional tool for working with audio.

Many users mistakenly believe that editing sound requires downloading heavy third-party applications or transferring a file to a computer. It's not. The built-in features of the system allow you to trimm just a few touches of the screen. It's important to know where to look for this option, because the voice recorder interface can vary depending on the firmware version and region.

In this article, we will discuss in detail the regular methods of editing audio files on Xiaomi devices, we will also touch on the topic of working with a file manager and consider situations when the built-in tools are not enough, you will learn to save edited fragments as new files so that the original remains intact.

Use of the built-in editor in the application Record

The easiest and fastest way to change the length of an audio file is to use the functionality of the Mi Recorder application itself. In the latest versions of the shell, Xiaomi developers integrated a simple audio editor directly into the listening interface, which allows you to stay in the application and immediately save the result.

To get started, open the Record app on your desktop or in the Tools folder, and you'll see a list of all the saved files, sorted by date, select the record you want by clicking on it, and open a play screen with a sound wave visualization or just a timer, depending on your smartphone model.

Notice the bottom of the screen or the three-dot menu in the corner, and you'll find additional features, and you'll need to find a item that might be called Edit, Cut, or have a scissor icon, and in some versions of MIUI, this button only appears after you click on the option menu.

• 🎧 Click on the play button to listen to the file and understand where the extra snippets are.
• ✂️ Select the “Edit” option in the file action menu.
• 📍 Move the start and end sliders of the allocation on the timeline to indicate the desired area.
• 💾 Click Save to create a new copy of the file with cropped content.

⚠️ Note: The staff editor in the Xiaomi Record app often works in Save As mode, which means that it does not change the original file, but creates a new copy of it with the selected fragment.

The interface of the editor may be different. Some models will show two vertical lines that limit the playback area; others will show a more advanced wave that can accurately see bursts of voice and silence. The accuracy of the sliders installation depends on the screen diagonal and the resolution of your Xiaomi.

Once you've selected the desired area, the system will suggest saving the result. Be sure to give the new file a clear name so as not to get confused with the versions. The saving process is instantaneous, since the phone does not recode the entire file, but only changes the metadata of the beginning and end of playback.

Configure the recording parameters to simplify editing

The quality and convenience of post-processing depends on the settings you chose before recording. The Mi Recorder app has a settings menu that allows you to adjust the bitrate, file format and even the sound source. The correct configuration here will help you avoid compatibility issues when trying to trim.

Go to the app settings (usually the gear icon or the three dots in the top right corner of the record list). Find the "Write Quality" or "Format" section. The default format is often M4A or MP3 with a high bitrate. There's enough medium-quality for speech to reduce file size and speed up the editor.

If you plan to edit records frequently, it is recommended to choose lossy formats such as MP3, as they are easier to handle with mobile processors. Non-compression formats such as WAV take up a lot of space and can be run longer on Redmi's budget models.

You should also pay attention to the Background Recording feature, which, if it's turned off, will keep the phone screen from going out during dictation, allowing you to visually control the process, which is useful if you want to stop recording immediately after the end of the speech, minimizing the tails that you have to cut.

File management through File Manager

Sometimes the built-in editor is missing, or it doesn't work properly with long files, and you can try File Manager, but it's worth noting that Xiaomi's standard file manager doesn't cut audio files directly like video, but rather serves as a tool to prepare or move a file to a third-party editor.

However, through the file manager, you can quickly find where your record is physically stored.The path to files usually looks like internal memory. → MIUI → sound_recorder. Knowing the exact location, you can copy the file to the cloud or to your computer for more complex processing if mobile tools can not cope with the problem.

In some versions of the shell, if you press the audio file long enough, a context menu may appear in the conductor. Check if there is an "Open with Help" option. If you install a third-party audio editor, the system may suggest opening the file through it directly from the conductor, which will speed up the process.

Using a file manager is also necessary if you want to clear the memory after making many cropped copies.Duplicate files can take gigabytes if you record long lectures daily.Regular folder revision sound_recorder It will help to maintain the speed of the smartphone.

Third-party applications for advanced pruning

Xiaomi’s regular tools are good for fast trimming of a piece of sound, but they don’t allow you to do a smooth attenuation (fade-in/fade-out), glue several files or remove noise. These tasks will require installing specialized software from Google Play. The market offers a lot of free solutions that will turn your phone into a mobile studio.

One of the most popular and functional applications is Lexis Audio Editor, which provides a full-fledged waveform interface that allows you to see and cut any artifacts with millisecond accuracy. It supports multitrack editing and various effects.

Another great option is the MP3 Cutter and Ringtone Maker, which is a simpler tool that is sharpened specifically for quick cropping and ringtones creation. If your goal is just to cut a piece and put it on the phone, complex editors can be redundant, and this option will work perfectly.

• 📱 Lexis Audio Editor: Professional tool with format support WAV, MP3, M4A. Allows the use of noise reduction and equalizer.
• ✂️ MP3 Cutter: Easy app for quick pruning without loss of quality. Perfect for creating ringtones.
• 🎚️ AudioLab: All-in-one combine harvester, including cropping, conversion, recording and changing playback speed.

⚠️ Warning: When installing free audio editors, be careful of permissions. Many require access to microphones and files. Try not to provide access to contacts or geolocations unless the audio application requires it.

Once you install a third-party application, the algorithm remains the same: you open a file through the application, select the area and save the result. The main advantage of third-party software is the ability to more accurately control visually and the Undo function if you cut off the excess.

Creating a ringtone from a cropped recording

Often users cut the recorder just to set a unique notification sound or ringtone. On Xiaomi smartphones with a shell MIUI and HyperOS, this process has its own peculiarities. It is not enough to trim the file — it needs to be saved correctly and placed in the right directory.

Once you have clipped the recording (by regular means or through the application), when saving, select the option “Save as a ringtone” (if available in the editor used). If this option is not available, just save the file to the phone memory. Then go to Settings → Sound and vibration → Phone call.

In the tone list, scroll down to the end, there should be a "Select a ringtone from files" button or a "+" icon. The system will suggest selecting an audio file from memory. Find your cropped recording, and it will appear in the general list of available tunes. Now it can be assigned to a contact or to all incoming ones.

For messages (SMS, messengers), the procedure is similar, but you need to choose in the section “Notification Sound”, which is a great way to personalize your smartphone using, for example, a funny phrase from a friend or an important voice snippet from a work call.

Problems in pruning and their solution

Despite the simplicity of the process, users may encounter difficulties, most often with file formats or access rights, for example, if the recording was in a format that the system reads as secure or non-standard, the editor may refuse to open the file.

Another common problem is a broken file after saving, which can happen if the phone is dead or the system crashes during the process of saving or trimming the record, in which case the file can be played in jerks or not opened at all.

If the in-house editor gives an error, try converting the file to a more common format (e.g., from M4A to MP3) before cropping. You can use online converters or converter apps that are also available in the Play Market.

💡

Always make a copy of the file before any manipulation (trimming, converting, formatting), and it is almost impossible to recover a deleted or damaged dictaphone record, especially if it was an important interview.

It is also worth considering that very long recordings (several hours) can be processed slowly, in which case it is better to break the process into stages or use more powerful applications optimized for working with large amounts of data, such as AudioLab.
