How to Cut Music on Xiaomi Redmi Note 8T: From Built-in Tools to Professional Apps

Cutting audio files on a smartphone is a challenge that both amateur musicians and those who want to create an original ringtone or cut a favorite piece from a song. Xiaomi Redmi Note 8T based on MIUI offers several ways to solve this problem, but not all of them are obvious. Unlike flagship models, where multimedia functionality is more extensive, you will either have to use hidden features of the system or turn to third-party applications.

Many users mistakenly believe that cutting audio requires a computer or complex programs like Audacity. In fact, even on a budget Redmi Note 8T with a Snapdragon 665 processor and 4 GB of RAM, you can cut tracks right on the device - the main thing is to know where to look for the right tools. In this article, we will analyze 5 working methods: from a standard MIUI editor to professional mobile studios, compare them in speed, quality and convenience, and also reveal little-known chips that will simplify the work with audio.

The Redmi Note 8T features limited functionality in the built-in Music app (it doesn’t support editing), but this is offset by integration with Google Files and the ability to install third-party utilities. It’s important to note that when you trim some formats (such as.flac or.wav) may lose quality if you don’t configure the right settings. We’ll discuss this in detail in the section on file saving.

If you’ve previously tried to trim audio on Android and have had problems — for example, the app didn’t save changes or the final file had distortions — this guide will help avoid typical errors. We’ve tested all methods on the Redmi Note 8T with MIUI 14 (Android 11) and taken into account the nuances of this firmware, including the limitations on working with the MIUI folder and system sounds.

1.Pruning through the built-in “Cut” application (hidden MIUI function)

Few people know, but MIUI has a hidden tool for basic audio cropping that doesn't require any additional software installation, it's hidden in the Tools menu and works even without an Internet connection, the main advantage of this method is the lack of advertising and unnecessary permissions, and the minus is limited functionality (you can only cut a fragment, but not impose effects).

To find this tool:

1. Open the Tools app (the wrench icon).
2. Scroll down to the Multimedia section.
3. Select Cut (on some versions of MIUI it may be called Audio Editor).

The editor interface is very simple: you'll see the waveform of the track and two sliders to indicate the beginning and end of the fragment. Importantly, this tool only supports the formats.mp3 and.m4a — files in other formats will have to be converted in advance. After cropping, the file is saved to the folder MIUI/sound_recorder, and it can be immediately used as a ringtone or notification.

⚠️ Warning: If the sound is quieter or clicks after the clipping, check if the highlighted segment is silent at the beginning/end of the original track. The built-in editor MIUI cannot automatically cut the pauses.

The processing speed depends on the length of the track: for a song lasting 3-4 minutes, it takes no more than 10 seconds to trim, but if the file weighs more than 50 MB, the system may suggest shortening it before editing.

2.Using Google Files for Basic Trimming

Google Files (the default app on most Xiaomi devices) not only clears memory, but also edits audio files, a technique that is suitable for quick cropping without installing additional programs, but has a limit: the maximum length of the final fragment is 30 seconds.

Instructions for pruning:

1. Open Google Files and find the audio file you want.
2. Slip on it and select Open with → Audio Editor.
3. Move the sliders on the timeline to highlight the fragment.
4. Click Save – the file will appear in the Downloads/Audio folder.

The advantage of this method is automatic volume normalization, which is useful if the original track is recorded too quietly. However, the quality of the file being saved is reduced to 128 kbit / s, even if the source was in higher resolution. This is enough to create ringtones, but for professional use, you better choose another method.

If you need to crop a piece longer than 30 seconds, but you don't want to install third-party apps, you can use a workaround to split the track into several parts for 30 seconds, and then glue them back together with the same editor, but it will take much longer.

3. Professional cropping in the Lexis Audio Editor app

For those who need advanced features such as overlaying effects, changing pace or removing noise, Lexis Audio Editor is one of the few free apps on Google Play that supports multi-track projects and saves files in their original quality.

To cut the track in Lexis:

1. Install the app from Google Play (weight ~20MB).
2. Import the audio file through the File → Open menu.
3. Use the Scissor Icon (School Scissor Icon) to mark the fragment.
4. Click Cut and select Save as for export.

The main advantages of Lexis:

• 🎛️ Supports.flac,.wav,.aac formats without conversion.
• 🔊 Ability to adjust the bitrate when saved (up to 320 kbit/s).
• 📊 Frequency spectrum visualization for accurate trimming.
• 🎵 Built-in equalizer and effects (reverberation, compression).

The disadvantage is the free version of the advert that appears when you save the file. To disable it, you need to purchase a premium version for ~ 300 rubles. The application also requires permission to access files and a microphone (the latter is necessary to record voice on top of the track).

⚠️ Warning: When you first start, Lexis may request access to contacts — this is necessary for the collaboration function. If you don't need it, waive permission: it doesn't affect the basic editing functionality.

For the Redmi Note 8T with its modest technical specifications, Lexis works stably, but when processing files longer than 10 minutes, you can slow down, in which case it is recommended to close the background applications or use the No-Distract mode in the MIUI settings.

💡

If the file weighs significantly more than the original after trimming in Lexis, check the export settings: the application defaults to.wav (uncompressed sound) format. To reduce the size, select.mp3 with a bitrate of 192-256 kbit / s.

4. Creating ringtones through the MIUI Sounds app

If your goal is to make a song a ringtone or a notification melody, you don't have to crop the file in advance. MIUI has a built-in Sound app that allows you to assign any fragment of the track as a signal without changing the original file.

How it works:

1. Open Settings → Sound and vibration → Phone Sound.
2. Select Add Rington and specify the path to the audio file.
3. In the editor that opens, move the sliders to highlight the fragment (maximum 30 seconds).
4. Save the changes – the new ringtone will appear in the list of standard tunes.

Advantages of this method:

• ⚡ Instant application – no need to wait for file processing.
• 🔄 Ability to change the fragment at any time without re-trimming.
• 📱 No additional applications are required.

Limitations:

• ❌ Maximum fragment length is 30 seconds.
• ❌ You cannot save a cropped file separately (just as a ringtone).
• ❌ Only.mp3 and.m4a formats are supported.

This is ideal for people who want to quickly personalize notification sounds without going into editing, such as cutting a chorus of a favorite song or a movie screensaver and assigning it to an SMS or alarm clock.

5. Trimming through online services (without installing applications)

If you don't want to download additional software, you can use online audio editors, which work right in the browser and support most formats, and the main advantage is that they don't take up space on the phone, and the disadvantage is that they require a stable Internet connection and can limit the size of files that can be downloaded.

Top-3 online audio cropping service:

• 🌐 AudioTrimmer (audiotrimmer.com) – supports files up to 50MB, export to.mp3 and.wav.
• 🌐 BearAudio (bearaudiotool.com) – there is a function of noise removal and volume normalization.
• 🌐 MP3Cut (mp3cut.net) – allows you to crop and glue several tracks.

Instructions for working with online editors:

1. Open your website in Chrome or Mi Browser.
2. Download the audio file from your phone (click Choose File or drag the file into the browser window).
3. Select the fragment with sliders or specify the start and end times manually.
4. Select the format and quality of the export, then click Cut or Save.
5. Download the clipped file back to your phone.

Important nuances:

• 🔒 Before downloading the file, check that the site is using HTTPS (the lock icon in the address bar).
• 📶 Online services can compress audio when downloading/downloading, which degrades the quality.
• ⏳ Processing speed depends on your internet speed and server load.

⚠️ Warning: Some online editors (e.g. MP3Cut) add watermarks as a quiet voice message at the end of the track. To avoid this, use the Premium Download option (usually paid) or opt for ad-free services like BearAudio.

For Redmi Note 8T, it is recommended to use the traffic saving mode in the browser settings to reduce Internet consumption when downloading / downloading files. Also, before working with online services, clear the browser cache (Settings → Applications → Browser → Memory → Clear cache) to avoid processing errors.

6. Alternative methods: from converters to automatic scripts

If none of these methods work for you, consider alternatives that are suitable for specific tasks:

1. Converters with a pruning function

Apps like MediaConverter or Any Audio Converter can not only change the format of a file, but also trim it. This is convenient if you need to simultaneously convert.flac to.mp3 and cut out a fragment.

2 Automation through Tasker

For advanced users: Tasker can create a script that will automatically crop audio files to specified parameters (for example, the first 10 seconds of each track in a folder).

3. Terminal and FFmpeg

If your Redmi Note 8T has a Termux (Linux emulator) installed, you can use the ffmpeg command to prune accurately.

ffmpeg -i input.mp3 -ss 00:01:30 -to 00:02:15 -c copy output.mp3

This command cuts the fragment from 1:30 to 2:15 without transcoding (keeps the original quality).

pkg install ffmpeg

4. Trimming through video editors

Apps like CapCut or KineMaster can edit audio tracks in video, but they can also be used to cut audio cleanly. Just import the audio file as a background track, trim and export the project without video (selecting audio only format).

The choice of method depends on your goals:

• 🎧 For ringtones, there are enough built-in tools MIUI or Google Files.
• 🎶 For music mixes, it is better to use Lexis Audio Editor.
• 🖥️ For mass processing, FFmpeg or Tasker is suitable.
• 🌍 Online services are convenient for one-time pruning.

💡

On the Redmi Note 8T, the fastest way to trim is the built-in MIUI editor or Google Files, but for professional quality, it is better to use Lexis Audio Editor or FFmpeg.
