How to crop audio recording from a voice recorder on a Xiaomi phone: 5 proven ways

The built-in voice recorder on Xiaomi smartphones is an indispensable tool for quickly creating voice notes, interviews or lectures. But what if the recording is too long and the desired fragment is hidden in the middle? Cutting the audio directly on the phone saves time and eliminates the need to transfer files to the computer.

Current versions of MIUI (12 to 14) offer several ways to edit sound, from basic functions of a standard voice recorder to third-party applications with advanced capabilities. In this article, we will discuss all current methods, including hidden chips that are not written about in official instructions, special attention will be paid to preservation of sound quality and export formats.

If you've never edited audio on Xiaomi, don't worry: the process is intuitive even for beginners, the key is knowing where to look for the right options and how to avoid typical errors (such as accidentally deleting the original recording), starting with the simplest way - the built-in voice recorder editor.

1.Pruning through a standard Xiaomi voice recorder

The fastest way to cut audio is to use the built-in tools of the Dictaphone app (an icon with a microphone), a method that works on all Xiaomi, Redmi and POCO smartphones with MIUI 12 and later, including the latest version of HyperOS.

Algorithm of action:

1. Open the Dictaphone application and find the desired entry in the list.
2. Slip on the record - the player with a waveform will open.
3. Click on the scissors icon (or "Edit" in some versions).
4. Drag sliders on the timeline to highlight the desired fragment.
5. Click Save as a new file (important: the original will remain intact!).

Note that MIUI 14 has a preview feature, which allows you to listen to a selected snippet before saving, which helps avoid errors in accurate trimming. If you don't have an option, update the app via Google Play or the App Store (for global firmware versions).

💡

If the sound is quieter after pruning, check the microphone settings in Settings → Apps → Recorder → Permissions. Sometimes recording restrictions lead to a loss of volume.

Unfortunately, the standard editor does not support:

• 🎛️ Overlay of effects (noise reduction, equalizer)
• 🔄 Combining multiple files
• 📊 Exports to formats other than.m4a and.mp3

Editing through the Music appendix

Few people know, but Xiaomi's built-in Music player can cut audio files -- even those recorded by a voice recorder -- that's a great way to do it if you want to share a piece of music quickly through a messenger.

Instructions:

1. Open the Music app and go to the Local Music tab.
2. Find your record (usually in the Recordings or Recorder folder).
3. Slip along the track and select Edit (pencil icon).
4. Select the fragment with sliders and press Cut.

The advantage of this method is that it can be exported directly to WhatsApp, Telegram or WeChat without saving a copy.

• 🔊 Sound quality may be affected by conversion
• 📁 The file is saved in the player folder, not the recorder.
• ⏱️ There's no precise millisecond adjustment.

Third-party precision trimming applications

If built-in tools are not enough, look for specialized editors. Xiaomi will do:

Top.-3 audio-cutting:

To install third-party editors:

1. Download the app from Google Play or APKMirror (for models without Google services).
2. Give access to files in Settings → Apps → Permissions.
3. Import the record from the folder /sdcard/Recordings/ or /sdcard/MIUI/sound_recorder/.

Important: Apps like Lexis Audio Editor let you save projects for further editing, which is useful if you work with long interviews or podcasts.

4. Trimming through the file manager (for experienced)

This method is suitable for users who prefer to work with files directly, and you will need a file manager with an integrated audio player (for example, Mi File Manager or Solid Explorer).

Step-by-step:

1. Open Files and go to the folder with records (usually Recordings or sound_recorder).
2. Take a long time to tap the file and select Open with → Music.
3. In the player, click on three points → Edit → Cut.
4. Select the fragment and save it as a new file.

The advantage of this is that you can batch multiple files, for example, you can quickly trim the beginning of all the records in the folder.

⚠️ Note: When cropping through the file manager, some versions MIUI automatically delete the original file. Always check your save settings!

For Xiaomi models with HyperOS (such as Xiaomi 14 or Redmi K70), this method may not work – in this case, use a standard voice recorder or third-party applications.

5. pruning on the computer (for maximum quality)

If you need professional editing (for example, for a podcast or music track), it is better to transfer the file to the PC.

1. Connect your phone to your computer via USB-C (select File Transfer Mode).
2. Copy the record from /sdcard/Recordings/.
3. Use Audacity (free) or Adobe Audition for precision trimming.

Advantages of editing on PC:

• 🎧 Support for.wav,.flac formats without loss of quality
• 🎛️ Advanced tools (normalization, noise removal)
• 📊 Export to any format with bitrate setting

To transfer files without loss, use the original cable from the Xiaomi kit - cheap analogues can cause errors when copying large audio files.

6. Frequent mistakes and how to avoid them

Even with the seemingly simple audio trimming, Xiaomi users often face problems, and here are the most common ones and ways to solve them:

Problem 1: After pruning, the sound became robot-like

Reason: Too aggressive compression when saved. Solution:

• In the editor settings, select WAV or FLAC format instead of MP3.
• Set the bitrate to at least 192 kbps.

Problem 2: You can't cut a record longer than 30 minutes.

Reason: Limitation of the standard recorder.

• Break the recording into pieces with Lexis Audio Editor.
• Use a PC to edit long files.

Problem 3: The waveform disappeared during editing

Reason: File damage or incompatible format.

• Convert your entry to.wav via Online-Convert.
• Check the file for errors with VLC Media Player.

💡

Always check the format of the source file before cropping. entries from Xiaomi's voice recorder are saved by default to.m4a (AAC), which not all editors support correctly.
