Want to cut your favorite verse out of a song to put it on the phone, or shorten the podcast for a convenient listening experience? On the Xiaomi Redmi Note 7, you can do it without a computer — right in your smartphone. The 2019 model is still popular thanks to its balanced specs: a Snapdragon 660 processor, 3/4 GB of RAM, and a built-in audio editor in MIUI 10-12 that many users don’t notice.
In this article, we will discuss 5 proven ways to trim audio, from standard tools to specialized applications. We will focus on maintaining sound quality and output formats. If you have not worked with audio editors before, don't worry: all methods are adapted for beginners, with step-by-step screenshots and tips for eliminating typical errors.

1. Standard MIUI Editor: Hidden Function
MIUI for Redmi Note 7 has a built-in audio cropping tool, but it's hidden in the Music app menu (not to be confused with Google Play Music!).This method is suitable for basic cropping without effects and supports.mp3,.m4a and.wav formats.
To find the editor:
- Open the Music app** (an icon with a note on a white background).
- Select the track to cut and click on three dots. ⋮ top-right.
- In the menu, tap "Edit" → "Cut".
The editor interface is intuitive: sliders for the beginning and end of the fragment, a play button for pre-listening. Limitation: maximum length of the output file is 5 minutes. If you need to crop the track longer, use third-party applications (see section 3).
💡
Before cropping, copy the original file to another folder – the built-in MIUI editor overwrites the original audio file without warning!
2.The Music Cut App from Xiaomi
Xiaomi has released the official “Music Cutting” app (com.miui.musiceditor), which comes bundled with firmware but is often hidden from users. It supports smooth attenuation (fade-in/fade-out) and save to.mp3 with a bitrate of up to 320 kbps.
How to find and use:
- 🔍 Go to Settings. → All applications → Show system and find "Slice of Music"** (scissors icon on green background).
- 🎵 Open the application, click “Select audio”** and specify the file.
- ✂️ Drag the yellow markers on the timeline to highlight the fragment.
- 💾 Click Save and select the folder (I recommend Internal Storage). → Ringtones to make the file appear in the call settings).
The advantage of this method is that there are no ads or redundant permissions, but the interface is in Chinese (even in global firmware), so focus on icons. For Russification, you can install a patch through Magisk, but this requires root rights.

Third-Party Apps: TOP-3 for Redmi Note 7
If the built-in tools don't work, consider the specialized editors, and we tested 15 apps from Google Play and selected the 3 best for Redmi Note 7, taking into account the performance and compatibility with Android 9-11:
| Annex | Ratings. | Pluses | Cons | Reference |
|---|---|---|---|---|
| MP3 Cutter(Lexa Funk) | 4.6 ⭐ | ✅ Support for.flac✅ Tag editing✅ No watermarks | ❌ Post-conservation advertising❌ Restriction of 10 files/day | Download |
| WaveEditor(DevDNUA) | 4.4 ⭐ | ✅ Multi-track mode✅ equalizer✅ Exports to.wav | ❌ Difficult for beginners❌ Takes 50.+ MB | Download |
| AudioLab(AudioLab Apps) | 4.7 ⭐ | ✅ 20+ audioeffects✅ Silence pruning✅ Cloud synchronization | ❌ Paid ($2.99)❌ Registration is required | Download |
For the Redmi Note 7 with 3GB of RAM, we recommend MP3 Cutter – it consumes minimal resources (only 15 MB of RAM when working).If you need advanced features (for example, noise removal), try WaveEditor, but note that when processing files longer than 10 minutes, lags can occur.
4. Trimming through Screen Recording (non-obvious life hack)
If you want to crop a clip from a video (e.g., pull a sound from TikTok or YouTube), use the built-in Screen Recording feature** with the option "Write internal sound" enabled, which works without root rights, but requires a MIUI 12.5+.
Instructions:
- Activate screen recording: swipe down the notification panel and find the icon 🎥 Screen recording.
- Turn on the “Record Sound” option and select “Inner Sound” (not microphone!).
⚠️ Warning: When recording audio from certain apps (such as Netflix or Spotify) protection may be triggered DRM, And the sound will be distorted. Test this method on a short snippet before you record it.
5. pruning via PC (if nothing helped)
If the phone doesn’t have enough power to handle large files (such as a 50+MB.flac), transfer the audio to your computer and use desktop editors:
- 🎧 Adobe Audition (for free, for professionals).
To transfer files from Redmi Note 7 to PC:
- Connect your phone over USB, select File Transfer (MTP) mode.
- Copy the audio file into a folder on your computer.
- Edit in the selected editor and export to.mp3 with a bitrate of 192-320 kbps for the optimal ratio of quality to size.
- Move back to your phone to the Ringtones or Notifications folder so that the file appears in the audio settings.
☑️ Preparation for pruning on PC
6.Optimizing cropped audio for calls
If you cut a song for a ringtone or alarm clock, consider the limitations of MIUI:
- 🔔 Maximum length: 30 seconds (60 seconds for alarm clock).
- 📱 Supported formats:.mp3,.m4a,.ogg.
- 🔊 Optimum volume: normalize the sound to -16 LUFS (use MP3Gain or Audacity).
To install the clipped file as a call:
- Place the file in the Internal Storage → Ringtones folder (create it if it is not available).
- Go to Settings → Sound → Call melody.
- Select your file from the list (you may need to reboot your phone).
⚠️ Note: If the file doesn't appear in the call settings, check its metadata.Some editors save the audio as a "music track" rather than a "call." Correct this in the file properties (e.g., via via via via via MP3Tag).
Frequent mistakes and their solutions
When cutting audio on the Redmi Note 7, users face typical problems. Here's how to avoid them:
| Problem. | Reason. | Decision |
|---|---|---|
| The application will fly out when saved | Lack of RAM (relevant to the 3 GB version) | Close the background apps or use WaveEditor in “light mode” (Settings → Performance) |
| Cut file without sound | Incorrect format or bitrate | Export to.mp3 with a bitrate of 128-192 kbit/s |
| Distortions at the beginning/end of the file | There is no smooth transition (fade) | Enable the option "Fade In/Out"** in the cropping settings (available in AudioLab and WaveEditor) |
| The file does not appear in the call settings | Wrong folder or metadata | Place the file in Ringtones and check the tags through MP3Tag |
If the problem is not solved, try resetting the app settings (Settings → Apps → Cut Music → Storage → Clear Data) and this will return the standard editor settings without losing files.
💡
For stable audio editors on Redmi Note 7, leave at least 1 GB of free memory and turn off the power saving for the application in the battery settings.
