How to crop audio recording on Xiaomi phone: all ways without a computer

Cutting audio files on Xiaomi smartphones is a challenge that both amateur musicians and those who edit podcasts or simply want to remove unnecessary snippets from voice notes. Unlike video editors, the built-in audio tools in MIUI often go unnoticed, even though they are even in the basic models of Redmi and POCO. The problem is complicated by the fact that many users search for solutions through Google Play, unaware that the necessary functionality is already integrated into the firmware.

In this article, we’ll look at 5 proven ways to trim audio directly on your phone, from the hidden capabilities of the standard Records app to professional tools like Lexis Audio Editor. We’ll focus on the nuances of the latest versions of MIUI 14/15, where the audio editing interface has undergone changes. And if you work with voice messages from Telegram or WhatsApp, you’ll find special life hacks here to process them.

1. Standard Records app: Hidden audio editor

Few people know, but MIUI's default firmware has a Recording app (a microphone icon) that can not only record sound, but also edit it. The cropping feature is hidden in the file's detailed viewing menu, which is not on the home screen, which confuses many users.

To crop audio through Records:

1. Open the application and find the desired entry in the list.
2. Tap the file, then click on three dots. ⋮ top-right.
3. Choose to edit → Cut off.
4. Drag sliders on the timeline to highlight the desired fragment.
5. Click Save as a new file (the original will remain intact).

⚠️ Note: In some regional versions MIUI (For example, in India, there may be no pruning function, in which case use alternative methods from the following sections.

2.Editing through "Gallery": an unexpected lifehack

If you have Xiaomi on MIUI 14+, you can even cut audio through the Gallery app, which works for.mp3,.m4a and.wav files, but does not support.aac (used in instant messenger voice messages).

Instructions:

• 📁 Open the gallery. → Go to the Albums tab. → Audio.
• 🎵 Find the file you want and tap it. The toolbar will appear at the bottom.
• ✂️ Click on the scissors icon (Cut off).
• 🕒 Drag sliders to highlight the fragment (maximum accuracy - up to 0.1 seconds).
• 💾 Save the result as a new file or replace the original.

⚠️ Note: When cropping through the Gallery, files larger than 50MB may be processed with a delay.If a Redmi phone with 4GB of RAM or less, close all background apps before editing.

3.The Music app: Rington trimming

If the goal is to create a ringtone or a notification from an audio file, the easiest way to use the built-in Music app is to not only crop tracks, but also assign them to events (call, alarm, message).

How to do this:

1. Open the music and find the track in the library.
2. Put three points on it. ⋮ near-name → Set up how → Cut audio.
3. Select a snippet (maximum 30 seconds for ringtone, 5 seconds for notifications).
4. Save and select the action: Call, Alarm or Notification.

🔹 Limitations:

• 🎵 The length of the fragment is limited to 30 seconds.
• 📱 Not all models. POCO Support this function (checked for the POCO X5 Pro - working on POCO M4 Pro - no).
• 🔊 Quality is only maintained for files.mp3 and.m4a.

💡

If you need to crop audio longer than 30 seconds, first split the file into parts through the Lexis Audio Editor app, and then save each piece as a separate ringtone.

4. Third-party apps: top-3 editorials for Xiaomi

If the built-in tools don’t fit (like putting effects on or trimming.aac), third-party apps will come to the rescue, and we tested dozens of editors and selected the top three for Xiaomi:

Lexi Audio Editor – for professionals

🔹 Pros: support for all formats, multitrack editing, effects (echo, noise cancellation).

🔹 Cons: paid version is needed for export without watermarks.

MP3 Cutter – for quick trimming

🔹 Pros: simple interface, real-time preview, support for.aac.

🔹 Cons: Advertising in the free version.

WaveEditor – to work with waveform

🔹 Pros: audio visualization, accurate editing up to milliseconds.

🔹 Cons: difficult for beginners.

📌 Tip: Check the permissions of the application before installing. Some editors (such as AudioLab) request access to contacts and SMS — These are unnecessary permissions for audio cropping.

5. cropping voice messages from messengers

Voice messages from Telegram, WhatsApp or Viber are saved to a phone in.ogg or.aac format that are not supported by standard MIUI tools.

1. Download the file from the messenger (in Telegram: hold the message → Save to the gallery).
2. Rename the extension from.ogg to.mp3 (use Files or Solid Explorer).
3. Open in MP3 Cutter or Lexis Audio Editor and trim.
4. Save it in.mp3 format, and you can now send the file back to chat.

⚠️ Note: When converting.ogg →.mp3 If accuracy is important, use WaveEditor to work with the original format.

💡

Voice messages from WhatsApp are automatically saved in the folder /WhatsApp/Media/WhatsApp Voice Notes/. To find them, turn on the display of hidden files in the Files app (three dots → Settings → Show hidden files).

6 Automation: Pruning via Tasker or Shortcuts

If you regularly need to cut audio from one template (e.g., delete the first 5 seconds from podcasts), you can automate the process.

• 🤖 Tasker (for advanced users): Creates trigger tasks (for example, when you save a new file to a folder) Downloads/Audio cut off the first 3 seconds).
• 🔄 Shortcuts (simple): Records the sequence of actions (open the file) → cut off → keep) in one tap.

Example of script for Tasker:
