How to crop recording from a voice recorder on the phone Xiaomi Redmi Note 7: 5 ways

Recording voice notes on the Xiaomi Redmi Note 7 is a convenient way to capture important information, interviews or lectures. But what if there are unnecessary pauses, noise or unnecessary fragments in the recording? Cutting audio directly on the phone saves time and eliminates the need to transfer files to the computer. In this article, we will examine all the available ways to edit records, from built-in tools to specialized applications.

It is important to understand that the quality of the cropping depends not only on the method chosen, but also on the format of the original file. Redmi Note 7 defaults to.m4a (AAC), which is supported by most editors. However, if you use third-party recorders, the format may differ - for example,.mp3 or.wav. This affects the choice of program for cropping.

We tested all of the methods below on the Redmi Note 7 with MIUI 12.5 and later, and if your phone runs on a different shell (like MIUI 14), the interface may be slightly different, but the principles remain the same.

1.Pruning through a standard Xiaomi voice recorder

The easiest way is to use the built-in Dictophone app, which is pre-installed on all Xiaomi smartphones and supports basic trimming without installing additional software. Here's how it works:

1. Open the Dictophone app and find the desired entry in the list.
2. Tap the recording to open it to the full screen.
3. In the lower right corner, click on the Edit icon (scissors).
4. Drag the blue sliders to the beginning and end of the fragment you want to save.
5. Click Save – the system will prompt you to replace the original or create a copy.

⚠️ Note: Xiaomi’s built-in editor doesn’t support multiple cropping of a single file. If you saved the edited version and want to cut it again, you’ll have to work with a new copy. There is also no function of pre-listening the selected fragment before saving - this can be uncomfortable with accurate settings.

Make sure that the record is not password protected|Listen to the original to highlight key points|Battery charge above 20% (for long files)|Free space on the phone (copy takes as long as the original)-->

If you need to crop a record to within a millisecond, the standard tool might seem too rough, and in that case, you'd better use third-party applications, which I'll talk about later.

2.Editing through the Music app (MIUI)

Few people know, but MIUI has a hidden feature of clipping audio through the standard Music app, which is a good method if you want to not only shorten the recording, but also convert it to MP3 for easy use.

1. Open Files and find the Recordings (or Records) folder where audio files from the recorder are stored.
2. Long click on the file → “Open with” → select “Music”.
3. In the player, click on the three dots in the upper right corner → “Edit audio”.
4. Drag sliders to select a fragment and click "Save".

The advantage of this method is the ability to change the bitrate (sound quality) when saving. For example, if the source file weighs too much, you can reduce its size by choosing a bitrate of 128 kbit / s instead of the standard 192-256 kbit / s.

⚠️ Note: When converting to MP3 The recording metadata (date of creation, duration of the original) is lost through the Music app. If it is important, pre-backup the file.

3.Using Google Drive for Trimming

If you prefer cloud-based solutions, Google Drive offers a built-in audio editor, which is convenient if you want to share a cropped recording immediately after editing.

1. Download the recording from the recorder to Google Drive (via the app or browser).
2. Open the file → click on three dots → Open with the help → Google Drive (web version).
3. In the player, select the "Cut" tool (scissors).
4. Specify the beginning and end of the fragment, then click "Save".

The main advantage of this method is access from any device, you can start cropping on your phone and finish on your computer, and Google Drive automatically saves the history of changes, which allows you to roll back edits if you do not like the result.

Cons:

• 🔴 Requires a stable Internet connection for downloading / downloading.
• 🔴 File size limit – up to 250MB for free accounts.
• 🔴 No function to normalize volume or remove noise.

Third-party precision trimming applications

If you don't like the built-in MIUI tools, consider the specialty apps. We tested the three most popular variants for the Redmi Note 7:

4.1. Lexis Audio Editor

Lexis Audio Editor is a powerful multi-track mixing editor, suitable for professional processing, but can seem difficult for a beginner.

• 🎛️ Pruning to within 1 ms.
• 🎛️ Noise removal and volume normalization.
• 🎛️ Exports to MP3, WAV, FLAC.
• 🎛️ Battery economy: charge consumption is minimal.

4.2. WaveEditor

It's a simpler, intuitive interface, perfect for quick pruning and effects (echo, reverberation).

• 🎧 Pre-listening of the fragment before saving.
• 🎧 Support for batch processing (packet trimming of several files).
• 🎧 Built-in equalizer.

4.3. MP3 Cutter and RingTone Maker

Optimized for ringtones, but also for cropping voice recordings.

• 🔊 Automatic definition of silence (removal of pauses).
• 🔊 Export directly to the Ringtones folder.
• 🔊 No advertising in the premium version.

Important: When installing third-party apps, give them access to only the records folder, not the entire repository, which will reduce the risk of personal data leakage.

5. pruning on a computer (for complex tasks)

If the recording requires deep processing (noise removal, volume alignment, music overlay), it is better to transfer it to the PC.

1. Connect the Redmi Note 7 to your computer via USB (select File Transfer mode).
2. Copy the entry from the Internal Storage folder → MIUI → sound_recorder.
3. Open the file in Audacity (free editor) or Adobe Audition (professional tool).
4. After pruning, export the file back to your phone.

Advantages of this method:

• 💻 Accuracy of editing at the level of individual samples.
• 💻 Access to extended filters (background removal, compression).
• 💻 Ability to work with files of any size.

Disadvantages:

• 🖥️ It takes time to transfer files.
• 🖥️ You need skills to work with audio editors.

💡

If you frequently edit entries on a PC, set up automatic folder sync sound_recorder Google Drive, Dropbox, so files are always on hand.

6. Frequent mistakes and how to avoid them

When you trim a Redmi Note 7, users often face typical problems, and here's how to prevent them:

⚠️ Note: If the file is not played after pruning, check its format. Some applications (for example, Telegram) do not support the file.m4a — convert MP3 through "Music" or third-party programs.

Problem 1: After saving, the clipped recording sounds quieter than the original.

Solution: In the Music app, enable the "Normalize Volume" option before saving. In third-party editors (e.g., Lexis Audio Editor), use the "Compressor" tool.

Problem 2: When you trim through Google Drive, the file is saved without extension.

Solution: Rename the file manually by adding.mp3 at the end, such as writing 1.mp3.

Problem 3: You can’t cut a record for more than 30 minutes.

Solution: Split the file into parts using the MP3 Splitter app, then trim each fragment separately.

💡

Always back up the original recording before pruning, and even the most reliable applications can fail, and it will be impossible to recover lost data.
