How to crop recording in the Xiaomi voice recorder: 3 working methods + editing tips

Xiaomi voice recorder recordings often contain unnecessary pauses, noise, or unnecessary snippets at the beginning/end. Cutting audio helps save space on the device, make listening easier, and prepare the file for sending. This article provides step-by-step instructions for the standard Dictaphone app (MIUI 12–14 versions), as well as alternative methods for models where the cropping function is hidden or absent.

Many users are facing a problem: in some Xiaomi firmware, the trim button disappears after the update or is not initially available, we will analyze how to return this feature through settings, which third-party tools are safe to use, and how to maintain sound quality when editing. We will pay special attention to the nuances of working with.m4a and.mp3 formats, which are most often generated by the Redmi and POCO voice recorder.

If you want to quickly remove the beginning or end of a recording, the standard editor in Xiaomi Recorder is enough, but for complex editing (insert silence, overlay music), you will have to use third-party applications. Below you will find a comparison of built-in and external tools with the pros and cons of each.

1. Trimming recording through a standard Xiaomi voice recorder

In most Xiaomi smartphones (Redmi Note 10/11/12 series, POCO X3/X4/X5, Mi 11/12), the built-in voice recorder supports basic trimming. The feature is available directly in the recording player interface, but its location depends on the version of MIUI.

To crop the audio file:

1. Open the Dictaphone app (mic icon).
2. Find the right entry in the list and tap it.
3. In the bottom panel of the player, click on the scissors icon (✂️) or edit.
4. Drag the blue sliders on the timeline to highlight the desired snippet.
5. Click Save – the system will prompt you to replace the original or create a copy.

⚠️

Note: In MIUI 14, on some devices (Redmi Note 12 Pro+, Xiaomi 13T), the trimming button can be hidden behind a long tap on the record. Hold your finger on the file for 2-3 seconds until the context menu with the option to Cut appears.

The standard editor allows you to crop only the beginning and end of the entry, but does not support:

• 🔇 Removing fragments from the middle of the file.
• 🎛️ Volume control or noise cancellation.
• 🔄 Save in other formats (original only.m4a).

2.Why may the crop button be missing?

If your recorder does not have a cropping function, the reasons may be as follows:

• 📱 An outdated version MIUI (Update the firmware through Settings → The phone. → System updates often solve the problem.
• 🔧 Regional restrictions. Some firmware for India or China has disabled. Check the region in Settings → Additionally. → Region.
• 🛠️ Modified firmware (castom or lightweight) In such cases, the recorder can be cut down.
• 📁 When the audio is not played, the system automatically hides the editing tools.

⚠️

Attention: On devices with MIUI for Russia (e.g. Redmi) 10C or POCO M4 Pro) the crop button may be called Modify and be in the three-point menu (⋮) noteboard.

If the firmware update did not help, try resetting the voice recorder settings:

1. Go to Settings → Applications → Application Management.
2. Find a recorder and select a Warehouse.
3. Click Clear the cache and Reset the settings.

Check out the MIUI version (Settings → About the phone)

3. Alternative methods of pruning without third-party applications

If the built-in feature is not available, use the hidden MIUI features or system tools:

Method 1: Through the Gallery (for.mp3) recordings

Some recordings of the recorder automatically appear in the Gallery in the Audio section, where the basic editor is available:

1. Open the gallery. → Albums. → Audio.
2. Select the entry and tap on the pencil icon (Edit).
3. Cut the file with sliders and save it.

Method 2: File Manager (MIUI File Manager)

If the record is stored in the device memory:

1. Open the files. → Audio.
2. Find the file (usually in the Recordings folder or MIUI/sound_recorder).
3. Slip on the three-point menu (⋮) and choose to cut.

Method 3: Google Voice Assistant

For quick trimming without installing programs:

1. Say, "OK Google, open the recorder."
2. Select the entry and ask: "Short the beginning for 10 seconds."
3. The assistant will offer to save the modified file.

⚠️

Note: The voice method only works for recordings shorter than 5 minutes and can distort metadata (date of creation, tags).

4. Third-party applications for advanced pruning

If built-in tools aren’t enough, use specialized editors. We tested 5 popular apps for compatibility with Xiaomi:

🔹 Recommendation for Xiaomi: For recordings from a voice recorder (.m4a) Lexis Audio Editor is better suited – it processes metadata correctly MIUI (If you want a free option, try WaveEditor, but note that it does not save the original date of creation of the file.

📌 How to Transfer a Post to a Third-Party Editor?

1. Open the recorder, find the file and tap Share.
2. Select Save to Files (Downloads folder).
3. In the editor, import the file from the Internal Drive → Download.

💡

Before editing in a third-party app, check the export quality settings. 64-128 kbps is enough for voice, but for music or interviews, choose 192-320 kbps.

5. How to crop a recording on a PC (for accurate editing)

If you want to delete snippets from the middle of a file or apply effects, you should use desktop software, even free tools will do:

Method 1: Audacity (Windows/macOS/Linux)

Instructions:

1. Connect Xiaomi to your PC and copy the entry from the Internal Storage folder → MIUI → sound_recorder.
2. Open the file in Audacity (download from the official website).
3. Select the unnecessary fragment with the mouse and press Delete.
4. Export to File → Exports → Exports to MP3.

Method 2: Online editors

For quick trimming without installing programs:

• 🌐 MP3Cut — supportive.m4a and.mp3, maximum file size of 50 MB.
• 🌐 Audio Joiner – allows you to combine and trim fragments.

⚠️

Warning: Online services upload your files to their servers and do not use them for sensitive records (such as business conversations or personal conversations).

Important: When pruning in Audacity,.m4a files from Xiaomi's voice recorder may lose metadata (write time, device model). To save them, go to File → Properties before exporting and manually fill in the fields.

6. Frequent mistakes and how to avoid them

When trimming records, Xiaomi users often face the following problems:

• 🔊 Distortion of sound after preservation - occurs when compressed in.mp3 Solution: Choose a format.m4a (AAC) or bitrate not lower than 128 kbit/s.
• ⏱️ Non-saving cropped file - check the permissions for voice recorder in Settings → Annexes → Permits → Warehouse.
• 📱 Closing the application when trimming – free up RAM (close background programs through Recent Apps).
• 🔄 Lose the original after saving – always choose the option to Save a copy, not Replace.

🔹 How to Restore a Cut Recording?

If you have accidentally saved the changes over the original:

1. Check the Recycle Bin in Files (Recently Deleted).
2. Use recovery programs like Recuva (for PC) or Dumpster (for Android).
3. If the recording has been synced to Mi Cloud, check the web version of the cloud at https://i.mi.com.

💡

Always back up important records by sending them to yourself via Telegram or email. Xiaomi's built-in tools don't have a "Cancel" function after saving.

Cut files often take up less space, but they can be further optimized without losing quality.

• 📉 Size reduction: Convert to.opus (good compression format) via Audio Converter.
• 🔇 Noise Reduction: In Lexis Audio Editor, use the Noise Reduction filter (levels 20–30%).
• 📤 Easy sending: For messengers (WhatsApp, Telegram) crop files up to 15-20 MB, otherwise they will shrink automatically.
