How to crop recording on the tape recorder Xiaomi Redmi: 3 ways without installing programs

The built-in voice recorder in Xiaomi Redmi smartphones is an indispensable tool for recording lectures, interviews or voice notes. But what if there were unnecessary pauses, noise or unnecessary phrases at the beginning or end of the file? Many users do not suspect that you can cut audio directly in a standard application without installing additional programs.

In this article, you will find 3 proven ways to crop records on Redmi Note 10/11/12, Redmi 9/10 and other models with the shell MIUI 12/13/14. We will understand how to work with the timeline, save changes without loss of quality and avoid typical errors.

If you've used third-party editors like Lexis Audio Editor or WavePad before, you should give them up -- MIUI has everything you need, you know where to look for the options you want, and then you'll have a step-by-step picture guide, a method map, and answers to a lot of questions.

1. Method 1: Trimming through the built-in voice recorder editor

The easiest method is to use the built-in tools of the Dictaphone app, which works on all Xiaomi smartphones with MIUI 12 and later, including the Redmi Note 11 Pro, Redmi 10C and even budget models like the Redmi A1.

1. Open the Dictaphone app (the microphone icon on the desktop).

2. Find the desired entry in the list and tap it - the player will open.

3.At the bottom of the screen, click on the scissors icon (✂️) or select Edit in the menu (three dots in the upper right corner).

And then you'll see a waveform timeline, and you can pick out the unnecessary fragment and delete it, and importantly, MIUI 14 has a pre-listening feature that helps you define the edges of the clipping.

• 🎵 Slice highlighting: swipe the scale to indicate the beginning and end of the desired segment. Markers can be dragged to fine-tune the markers.
• ✂️ Remove: Click Cut (or Remove highlighted in older versions) MIUI). The system will allow you to save the changes.
• 💾 Save: Select Save as a new file to avoid losing the original. The new entry will appear in the list marked (cut off).

Note that if the recording is longer than 10 minutes, the editor can slow down when rewinding, in which case it is better to use the second method (via the Gallery).

💡

To speed up navigation over long entries, zoom in on the timeline – spread two fingers across the screen, as in maps.

2. Method 2: Editing through the Gallery app

Few people know, but in MIUI, audio files can be edited directly in the Gallery, a method that is suitable for records stored in a Recordings folder or on a memory card, an advantage of the method: there are additional effects (for example, noise removal) that are not available in a standard recorder.

Instructions:

1. Open the Gallery app.
2. Go to the Audio section (or find the recording through search).
3. Slip the file and select Edit (pencil icon).
4. In the editor that opens, select the desired fragment and click Cut.
5. Save the changes – the file will be overwritten or a copy will be created (depending on the settings).

The Gallery also has a volume normalization feature, which is useful if the recording is too quiet. After pruning, click Effects → Improve the sound.

Make sure the file is not password protected | Check the free space on the device (needs at least 20% of the file size) | Turn off the power saving mode for stable operation |Close the background applications that consume memory-->

3. Method 3: Trimming through "Tools" (MIUI Tools)

Xiaomi smartphones have a hidden Tools menu that contains useful utilities, including an audio editor, which is suitable for advanced users, as it allows you to work with several tracks at the same time and customize bitrate.

To find the tool:

1. Open Settings → Applications → Tools (or use a search by settings).
2. Select the Audio Editor (some firmware called Sound Recording).
3. Import the file through Open and start editing.

Extended options are available here:

• 🔊 Mixing tracks: you can overlay music on voice recording.
• ⏱️ Precise trimming: step of selection - 0.1 seconds (vs. 0.5 in the Gallery).
• 📊 Spectrum analysis: frequency visualization for professional processing.

⚠️ Note: In some regional firmware MIUI (For example, for Europe, the Tools section can be hidden. To activate it, run the command to ADB:

adb shell pm enable com.miui.tools

Then restart the phone and the menu will appear in the settings.

4.How to save a cropped recording without loss of quality

One of the most common questions is, "Why did the sound get worse after pruning?" The fact is that when you save MIUI, the default compresses the file to a bitrate of 96 kbit / s. To avoid this, you need to manually select export options.

Follow these steps:

1. Then, after you have finished, click on the three steps.
2. In the export window, tap on Settings (cog in the corner).
3. Select: WAV (lossless) or AAC 320 kbps (optimal balance) Quality: Original or High.

Music/Edited

⚠️ Attention: Files in format WAV It takes up 10 times more space than MP3. If you have little memory, choose. AAC 192 kbps is the gold standard for voice recordings.

5. Common Mistakes and How to Avoid Them

Even power users sometimes have trouble cropping audio on Xiaomi Redmi. TOP-5 errors and ways of solving them:

1. File not saved: Reason: not enough space on the device or SD-map formatted in exFAT (MIUI It doesn't work well with this format. Solution: release. 1-2 GB memory or reformat the card into FAT32 PC.
2. The cropped fragment is missing: Reason: You chose Save Changes instead of Save as a new file. Solution: Check the Recycle Bin in the Files app - the original could have gotten there.
3. Sound became robotic: Reason: When you save it, you turn on the playback speed effect. Solution: cancel the action and export the file without any additional effects.

Another common problem is that the time stamps disappear in long records, which happens when you crop a file in the Gallery. To save the tags, only use the built-in voice recorder or MIUI Tools.

💡

Before you trim important entries (interviews, lectures), always back up the original. To do this, send the file to your mail or to the Mi Cloud (in MIUI it takes 2 clicks: Share → Mi Cloud).

6. Alternative cropping applications (if standard ones do not fit)
