Owners of Xiaomi, Redmi and Poco smartphones often face the need to save an important conversation, whether it is a business meeting or a personal conversation. the built-in functionality of the MIUI system allows you to automatically or manually record an audio stream, but after the call is completed, many users are lost, not knowing where to look for the received files. Understanding the Android file structure on the devices of the Chinese brand is the key to fast access to the archive.
The system logic of the call recorder on these devices differs from the usual third-party applications installed from the Google Play store. The standard save path is rigidly tied to system folders, which ensures stability of work, but sometimes makes it difficult for inexperienced users to find. Files are not copied to shared folders with music or voice notes, but lie in a specialized directory.
In this article, we will take a closer look at the algorithms for finding audio files, look at the differences in paths for different versions of the shell, and learn how to adjust automatic synchronization. You will learn how to change the standard behavior of the system so that the recordings are stored exactly where you want, and how to avoid data loss when cleaning the cache.
Standard path to files through file manager
The fastest and most reliable way to find a record you are interested in is to use the built-in Explorer (or Files) application. By default, all audio files created by the system recording module are placed in the root directory of internal memory. You need to open the application, select the Internal Drive section, and find a folder called MIUI.
Inside this system folder, you should go to the directory sound_recorder. This is where all the audio information generated by standard Xiaomi applications is stored. However, to avoid getting confused with the many files from different recorders, pay attention to the attached folder. call_rec. In the file. call_rec Files created exclusively during telephone conversations, unlike regular voice notes.
The complete path to the desired file is usually as follows: /storage/emulated/0/MIUI/sound_recorder/call_rec. If you use a third-party file manager, such as Total Commander or FX File Explorer, the navigation will be similar. Files are often formatted.m4a or.mp3, This allows them to be reproduced on any modern device without conversion.
⚠️ Warning: When cleaning memory through built-in system optimization tools, be careful.Some aggressive Cleanup settings can delete folder contents sound_recorder, if it is classified as cache, although this is rare on current versions MIUI.
Search for records through the built-in Dictophone application
An alternative and more visual search method is the use of the regular MIUI Dictaphone application, which is convenient because it does not require knowledge of file paths and allows you to immediately listen to, rename or delete an unnecessary entry. On your desktop or in the Tools folder, find an icon with the microphone image.
When you start the app, you'll notice the top of the screen, and you'll have tabs that change modes, and you'll need the Call Record tab, and if you switch to that, you'll see a list of all the saved dialogs, sorted by the date and time of the incoming or outgoing call.
The application interface allows you to perform basic manipulations of files without logging into the file system.
- 📱 Click on the contact name or number to listen to the recording.
- ✏️ Use the Edit button to rename the file or trim extra seconds.
- 📤 Send a file via messenger or mail using the “Share” button».
- 🗑️ Delete the recording by freeing up space on the device.
It's important to note that the MIUI Recorder app syncs to the file system in real time, and if you delete a file through a Explorer, it disappears from the list in the application, and vice versa. It's a single database, presented in different interfaces.
☑️ Checking the recording settings
Configure automatic recording and saving parameters
To avoid looking for a record button every time a call is made, you can set the system to automatically record all incoming and outgoing calls. To do this, open the Phone app (green handset), click on the three dots in the upper right corner and select Settings. Next, look for Call Record.
This menu provides flexible system behavior settings, you can choose All numbers for total recording or Selected numbers by adding only important contacts to the list, and you can also adjust the Record Mode option: you can choose recording without warning (the interlocutor will not hear the beep) or with a warning.
In some regions and firmware versions, there is a choice between MP3 and AAC (or M4A) formats. MP3 format is more versatile but takes up more space, whereas AAC provides better quality with a smaller file size, which is critical for devices with a smaller memory.
⚠️ Note: Call recording without audible notification may not be available in some countries due to legal privacy restrictions.
Hidden recording functions
Changing the conservation path SD-map
Audio recordings, especially in high quality, can take up a significant amount of internal memory. If your smartphone supports microSD cards, it makes sense to move the record store there, which will free up the internal space for installing applications and running the system.
To change the save path, go to the Dictophone settings (through three dots in the corner of the screen). Find the "Record settings" or simply "Settings" section. There will be "Save folder" or "Path to files." Click on it and select «SD-map».
Once the path is changed, all new records will automatically be created on an external medium, while the old files will remain in internal memory, they will have to be transferred manually through the file manager if necessary: MIUI/sound_recorder/call_rec.
💡
Use Class 10 or UHS-I speed memory cards to record calls. Slow cards can cause audio interruptions or audio artifacts during a conversation.
Sync with the cloud Xiaomi and Google Drive
To ensure data safety, it is recommended to set up automatic synchronization, which will protect your records from loss in the event of a phone breakage, theft or accidental reset. Xiaomi ecosystem offers an integrated cloud that seamlessly integrates with the recorder.
To activate synchronization with Xiaomi Cloud:
- Open the “Settings” of the smartphone.
- Go to the Mi Account (top menu line).
- Select “Cloud” and find the Dictator app in the list.
- Activate the synchronization switch.
Synchronization via Google Drive is also possible, although it often requires manual intervention or the use of third-party automation scripts, as direct integration "out of the box" for the call folder may not be available.
💡
Regularly syncing with the cloud is the only reliable way to ensure that important conversations are kept safe when a device is physically lost.
Comparison of save ways and file formats
Understanding the differences between record types and their location helps you navigate the file system more quickly, and here is a table that organizes information about paths and formats for different use cases.
| Type of record | Standard path | File format | Annex |
|---|---|---|---|
| Conversations (Calls) | /MIUI/sound_recorder/call_rec | .m4a / .mp3 | Telephone/Dictator |
| Voice notes | /MIUI/sound_recorder/rec_... | .m4a | Dictaphone |
| Screen recording (with sound) | /MIUI/screen_recorder | .mp4 | Screen recording |
| Third-party annexes | /Android/data/[Annex name] | Depends on the app. | Call Recorder et al. |
As you can see from the table, system call records have a strictly defined storage location. Third-party apps downloaded from the Play Market often create their own folders at the root or in the Android directory, which can confuse the user.
The.m4a format is a modern standard for audio compression, providing good quality at low weight.If you plan to transfer files to older devices or specific hardware, you may need to convert to.mp3, which is why there are many free online converters available.
