How to cut recording from a voice recorder on a Xiaomi phone: step-by-step instructions

Why Xiaomiโ€™s standard voice recorder canโ€™t cut records โ€“ and what to do

You recorded a long lecture, interview or meeting on a Xiaomi recorder, and now you need to cut fragments or break the file into pieces? Unfortunately, the standard Dictophone app (including versions for the Redmi Note 12, POCO X5 and other models) does not support audio sharing directly in the interface, but this does not mean you have to transfer files to your computer or search for complex programs.

In this article โ€” 5 Proven ways to share recording directly on your phone, including built-in tools MIUI, Third-party apps and little-known chips, and we'll compare them in speed, quality and time stamp retention, and we'll also show you how to avoid losing important pieces when editing. 13/14 HyperOS, where the algorithms of working with audio have changed.

โš ๏ธ Important: Always duplicate the original file to the cloud or memory card before editing โ€“ some applications save changes โ€œon topโ€ of the source, which can lead to data loss if a crash occurs.

Method 1: Use of the built-in MIUI editor (without installing applications)

With MIUI 12, Xiaomi has a hidden tool for basic audio editing that doesn't advertise on the menu, but works on most models (including Redmi 10C, POCO F4 and later).

  1. Open the Files app (Menu โ†’ Tools โ†’ Files).
  2. Go to the Recordings (or Recorder) folder where the records are stored.
  3. Click on the file you want and select Open with โ†’ Music (or โ€œMusic Playerโ€).
  4. In the lower panel will appear the button Edit (scissors) โ€“ tap it.
  5. Move the sliders on the timeline to highlight the snippet, then click Save as a new file.

โœ… Pros: does not require the Internet, maintains the original quality (AAC 128-192 kbps, working offline.

โŒ Cons: no smooth separation function (you have to save each fragment separately), does not support the format.m4a firmware.

File format (should be.mp3 or.aac)

Free space on the phone (minimum 200 MB)

Battery charge (at least 30%)

Power saving mode is off.-->

Method 2: The Lexis Audio Editor app is the best choice for Xiaomi

If the built-in tools are not good, we recommend Lexis Audio Editor, one of the few applications optimized for MIUI and HyperOS.

  • ๐Ÿ”ช Accurate separation with time stamps saved (useful for decrypting interviews).
  • ๐ŸŽ›๏ธ Volume normalization โ€“ eliminates the differences in sound between fragments.
  • ๐Ÿ“ค Export to the cloud (Google Drive, Mi Cloud) directly from the interface.
  • ๐Ÿ“ฑ Adaptive interface for screens with a cutout (like on Xiaomi) 13T).

Step-by-step:

  1. Install Lexis Audio Editor from Google Play (free version is sufficient).
  2. Open the entry through the File โ†’ Import menu.
  3. Click on the Scissors icon (Split) and move the sliders while holding your finger on the scale.
  4. For accuracy, use the +1c/-1c button for second-by-second settings.
  5. Save fragments through Export โ†’ MP3 (320 kbps).

๐Ÿ’ก Tip: if the recording is longer than 1 hour, pre-break it into parts for 30 minutes - so the application will work more stable.

Method 3: Online services (if you need to be fast and without installation)

If you don't have enough space on your phone or you're afraid to install third-party software, you can use online editors. We tested 3 services -- the results in the table:

โš ๏ธ Note: Online services do not guarantee confidentiality โ€“ if the record contains personal data (passport, medical), use offline methods.

How to cut through MP3Cut:

  1. Open your website in Chrome or Mi Browser.
  2. Click Select File and download the recording from your phone.
  3. Move the sliders to select the fragment (maximum accuracy - up to 0.1 seconds).
  4. Click Save and download the result.
How to speed up up the upload of large files to online editors?
Use Wi-Fi instead of mobile internet. compress the file before download (e.g., through the Audio Compressor app). Break the recording into 100MB pieces using Lexis Audio Editor (method 2).

Method 4: Automatic separation by silence (for lectures and interviews)

If the recording contains long pauses (for example, between interview questions), you can automatically break it by silence.

  1. Install Audio Splitter from Google Play.
  2. Select a file and activate Split by Silence mode.
  3. Customize: Silence threshold: -40 dB (optimum for voice recordings) Minimum pause: 2 seconds (to avoid breaking the speech).

Start

๐Ÿ“Š Example of the result: the recording of a lecture lasting 1 hour and 20 minutes was automatically divided into 12 fragments by topic (pauses between blocks - 3-5 seconds).

โš ๏ธ Warning: If there is background noise in the recording (air conditioning, street), pre-clean it through the Lexis Audio Editor (Noise Reduction function.

Method 5: Split through Google Drive (if you want to share snippets)

Little-known life hack: Google Drive can cut audio files without installing additional programs, which is convenient if you need to quickly send a piece of recording to a colleague or save it in the cloud.

Instructions:

  1. Upload the recording to Google Drive (Folder My Device โ†’ Audio).
  2. Open the file and press three dots (โ‹ฎ) โ†’ Open with help โ†’ Google Drive.
  3. In the bottom panel, you'll see a playback scale. Click on the scissors icon.
  4. Select the desired fragment and save it as a new file (Create a copy).

๐Ÿ” For models with HyperOS (Xiaomi 14, Redmi) K70): Check for an update for Lexis Audio Editor โ€“ new firmware has changed microphone access, and older versions of the app may not see the recordings.

If the record contains important information (court session, medical dictation), use only offline methods (methods 1, 2 or 4) - online services do not guarantee the safety of data.

Frequent Mistakes and How to Avoid Them

When editing audio on Xiaomi, users often face typical problems. Hereโ€™s how to prevent them:

  1. File doesn't open in editor: Check format - Xiaomi's standard voice recorder saves.m4a (AAC) records, but some apps only work with.mp3. Use Audio Converter to convert.
  2. After pruning, the sound disappeared: Chances are you saved the file in a low bitrate format. In Lexis Audio Editor, choose MP3 320 kbps or WAV.
  3. The app flies on long files: On phones with 4GB of RAM (like Redmi 9A), edit the records piece by piece or use online services.

๐Ÿ› ๏ธ If nothing helps: try clearing the Dictophone app cache (Settings) โ†’ Annexes โ†’ Dictaphone โ†’ Warehouse โ†’ Clear cache. Sometimes this solves file playback problems.

Can I share a record without losing the time stamp (for decryption)?
Yes, but only in Lexis Audio Editor (method 2) or Audio Toolkit (online), the built-in MIUI editor doesn't save any tags. If time stamps are important (for example, for court records), export the file in.m4a format with the Preserve Timestamps option enabled.
Why did the file become quieter after the clipping?
This is due to the normalization of volume in some editors. In Lexis Audio Editor, turn off the Auto Gain option before saving. If the sound is already lost, use the Amplify feature in the same app (increase the volume by +6 dB).
How to share a record on Xiaomi if the phone does not see the files of the recorder?
Check /storage/emulated/0/Recordings through any file manager (e.g. Mi File Manager). If there are no files: Open Recorder and check if the memory card is saved (Settings โ†’ Save Place). Reboot the phone - sometimes MIUI does not display fresh records without a reboot. If the records are missing after the firmware update, use DiskDigger to restore the audio.
Can I automatically break down the recordings by voice (e.g. question-answer)?
On a Xiaomi phone, this is only partially possible: Audio Splitter (method 4) can break files by pause, but does not recognize the change of speakers. To fully split voices, you need PC programs like Audacity with the Vocal Separation plugin.
How to keep the cut fragment in its original quality?
Use the format. WAV (uncompressed audio) or FLAC In Lexis Audio Editor: Select Export โ†’ Other formats. WAV (PCM) or FLAC (Disable the Resample option to save the original sampling rate. โš ๏ธ Keep in mind that WAV-Files take up 10 times more space than MP3.
