Xiaomi’s current smartphones, which run MIUI shells or the new HyperOS, allow users to record hours of audio material, whether it’s lectures, interviews or personal notes. Over time, the accumulated amount of data begins to occupy a significant part of internal storage, which can slow down the device. Deleting unnecessary files becomes not just a matter of order, but a necessity for stable system operation.
The cleaning process depends on whether the recording is stored in the system recorder or in the correspondence of popular messengers. Proper cleaning requires understanding the structure of Android folders so that you do not accidentally delete system-critical files or rare records that you planned to save. In this article, we will discuss all possible scenarios for working with audio files.
You will learn to manage your space effectively using standard system tools and third-party utilities. Secure removal ensures that sensitive information does not fall into the wrong hands, and the vacated space can be used to install new apps or photos.
Deletion of records through a standard dictaphone
The most obvious and most commonly used way to work with audio is the built-in Dictophone app, which automatically sorts records by date, which makes navigation easier. To delete one or more files, open the app and find the list you want at the bottom of the screen.
Press and hold your finger on a specific file to activate the allocation mode. Then you can select additional entries or use the "Delete All" function in the control menu. The system will request confirmation of action, since the process is irreversible without a backup.
💡
Before mass deleting old lectures or meetings, copy important files to your computer or cloud storage, as the standard shopping cart in Xiaomi’s recorder is often missing.
Importantly, some versions of the MIUI shell may hide the control menu behind a separate tri-point icon. If a long press does not trigger the selection menu, carefully examine the interface for an Edit button or similar item in the top corner of the screen.
Cleaning through File Manager Explorer
For deeper cleaning, when you want to remove not only the tracks themselves, but also free up space occupied by the cache or hidden copies, you better use the system Explorer, which gives you full control over the file system of the device.
Go to the Audio section or manually find the folder MIUI/sound_recorder. It stores all the records that are made by a standard application. You can sort files by size to quickly find and delete the largest records that take up the most space.
☑️ Check before deleting files
When working with files through Explorer, be especially careful. Deleting files from system folders such as Android/data can cause applications that use this data for their functionality to malfunction.
⚠️ Warning: Clean up in the storage settings may suggest removing "large files." Always check the content before confirming to avoid erasing important documents or media files that the system has mistakenly classified as junk.
Removal of voice messages in messengers
Voice messages on WhatsApp, Telegram and Viber often take up more space than voice recorders because of duplication in the cache. Deleting a message in a chat doesn't always mean it disappears completely from the device, as a copy can remain in the folder of the application's media files.
Telegram can use the built-in Memory Use feature to clear the voice cache, which allows you to delete files from the device, leaving them available for re-download in the cloud if necessary. WhatsApp is similar to the process: go to the storage settings inside the app.
Where is WhatsApp on Xiaomi stored?
For mass removal in chats, use the Clean Chat function, which will delete all of your correspondence history, including text, photos and voice, freeing up a significant amount of memory. Remember, it will be impossible to restore deleted correspondence without a pre-created backup.
Using the Security Application for Cleaning
Xiaomi provides a powerful built-in Security app that includes the Cleanup tool, which automatically scans the device for temporary files, app cache, and residual data that can be safely deleted.
Run the scan and wait until the analysis is complete, and the system will suggest removing the garbage, which is often where old voice recordings are also found if they were labeled temporary or cached, a quick way to do a superficial but effective clean.
However, it is worth considering that automatic algorithms are not always perfect: Deep cleaning requires manual verification, the application can miss large files in download folders or attachments in messengers that were not recognized as standard garbage.
💡
The Security app is a good tool for rapid prevention, but to ensure the removal of specific voice recordings, it is better to use the manual method through Explorer or Recorder.
Comparison of methods of deleting audio files
The choice of method of removal depends on your goal: whether you just need to make room or you need to guarantee the destruction of confidential information.
Below is a table that will help you choose the best option for your case, comparing the speed, safety and depth of cleaning of different methods.
| Method | Speed. | Security of data | Depth of cleaning |
|---|---|---|---|
| Through the Dictaphone | Tall. | Medium (files deleted) | Just the tape recorder. |
| Through the Conductor | Medium | High (User control) | Full (all folders) |
| Cache cleanup (Security) | Very high. | Low (automatics) | Surface (temporary files) |
| Resetting settings | Low (long training) | Maximum | Complete removal of everything |
Use Explorer if you need to pinpoint specific files by name or date, but if the goal is to prevent and speed up your smartphone, the built-in Security tools will be enough for regular maintenance.
Recovery of deleted voice recordings
If you accidentally delete an important record, there is a small chance of recovery, but you need to act quickly. Modern file systems mark the space as free to write, but the data itself can remain on the disk for some time.
First, check cloud services. If your Xiaomi account was enabled sync with Mi Cloud or Google Drive, a copy of the file could be saved there, and it is also worth checking the Recycle Bin folder in the Gallery or File Manager, if this feature is supported by your version of Android.
Recovery from internal memory requires specialized PC programs such as Dr.Fone or DiskDigger, and the effectiveness of these utilities depends on many factors, including root rights and the time elapsed since the deletion.
⚠️ Warning: Do not write new files to your phone after data loss. Each new photo or application can overwrite the memory sector where the remote voice recording was located, making recovery impossible.
