Modern Xiaomi and Redmi smartphones have powerful built-in functionality for automatic or manual recording of phone conversations, a feature that often becomes critical for preserving evidence, recording customer agreements, or simply for personal archives. However, once a call is complete, many users face difficulties: the built-in player can not display old files, and the standard gallery ignores audio formats. Where is this data physically stored in the file system?
Finding records is complicated by the fact that with each update to the MIUI shell or the new HyperOS operating system, the directory structure may change slightly. In addition, devices with Android 11 and above have strict security restrictions that hide system folders from third-party file managers. In this article, we will discuss in detail all possible paths to your audio files, how to extract them and solve typical playback problems.
Understanding the logic behind Xiaomi Recorder will allow you to not only find files, but also manage them effectively by backing up. We'll look at both the standard paths through the interface and direct access to the root file system through the computer, which is a knowledge that every smartphone owner needs to know when it comes to keeping voice information safe.
Search for records through the standard Dictaphone application
The most obvious and quick way to find a record you're interested in is to use the standard app, which is installed by default on all devices of the brand, usually called "Dictophon" or "Recorder" and has a characteristic icon with a microphone. Inside the application, all records, including phone conversations, are often sorted by date or have a separate tab.
To get to the list, open the app and look at the top of the screen, and you can have the Dictophone, Interview, and Phone tabs, and that's where all the automatic and manual recordings of incoming and outgoing calls are stored, and if you don't have tabs, try clicking three dots in the corner or swiping left-right, because the interface depends on the firmware version.
Each file in the list has a context menu, and you click on it, and you'll see the duration, the date of creation, and the subscriber number, and you can do the basic things: rename the file so you don't lose the essence of the conversation, send it via messenger, or delete it.
- π± Open the Dictophone app on the home screen or in the Tools folderΒ».
- π Switch to the Phone tab or find a list of all entries in the menu.
- βοΈ Click on the desired file to play or select βMoreβ to act on the file.
- π€ Use the βSendβ button to share a post via WhatsApp or Telegram.
β οΈ WARNING: When you clear the Dictophone app cache or delete its data through your system settings, the list of records within the application may disappear, although the files themselves often remain in memory.
Direct access through the file manager
If a standard application is not working properly or you need to copy many files to your computer at once, direct access to the file system will be the most effective solution.The standard Explorer on Xiaomi allows internal memory, but due to Android security policies, new versions can hide the Android folder.
The main way to record conversations on modern versions MIUI HyperOS is as follows: Internal memory β MIUI β sound_recorder β call_rec. It's in the directory. call_rec All audio files of telephone conversations are stored.m4a or.mp3, What provides good quality with a small size.
In older versions of the shell or on Android devices 10 The path may be different: Internal memory β MIUI β sound_recorder. Here, the files could be right at the root of the folder or in the subfolder with the date. MIUI, Check if it is hidden or use a computer to view it.
βοΈ File access check
For users who canβt find files through built-in Explorer due to Android 11 limitations+, It is recommended to connect the smartphone to the PC through USB-On a computer, system folder access restrictions are often less stringent, allowing you to copy the data directly to the destination folder.
Structure of file storage on different versions of MIUI and HyperOS
Xiaomi regularly updates the software, and with the new features, the organization of the data changes. Understanding the differences between versions will help you navigate faster if the standard path does not work. Below is a table that organizes the paths depending on the version of the system.
| System version | The way to the folder | File format | Features of access |
|---|---|---|---|
| MIUI 10 - 12 | /MIUI/sound_recorder/ | .mp3 /.aac | Direct access through any conductor |
| MIUI 13 - 14 | /MIUI/sound_recorder/call_rec | .m4a | Permission to access files is required |
| HyperOS 1.0 | /MIUI/sound_recorder/call_rec | .m4a | The Strict Limits of Android 14 |
| Global ROM | /Recordings/Call_rec | .mp3 | It is found on some models. |
It's worth noting that on Global ROMs, the structure may be different from the Chinese versions, and in some cases, the system creates a separate root folder, Recordings, which already has subdirectories for different types of recording, which is designed to be unified with other devices on pure Android.
If you upgrade from MIUI 12 to HyperOS, old records may stay in the old folder structure, and new ones may be written in the new way, so when looking for archival data, it makes sense to check both file locations.
Why is the Android folder hidden?
Viewing computer records
Listening to long conversations on a small smartphone screen is not always convenient, and the quality of the built-in speaker can distort the details of the conversation. Connecting to a computer allows you not only to conveniently listen to a file through a quality media player, but also immediately send it by mail or save it to the cloud.
Use the original to connect USB-After the connection on the smartphone screen will be a request for mode of operation USB. Select File Transfer or MTP. On your computer, open "My Computer," find your device, and follow the path indicated in the previous section, and copying files to your PC ensures they are safe even in the event of a phone crash.
If your computer can't see the folder or it's showing empty, try unlocking your smartphone screen. For security reasons, Android prevents you from accessing the file system while your device is locked. Also check if you have an ADB driver or standard MTP drivers installed if you're using Windows.
- π» Connect your smartphone to your PC with the original cable.
- π Unlock the screen and select the File Transfer modeΒ».
- π On PC, open the smartphone drive and go to the folder MIUI.
- π§ Copy files from sound_recorder/call_rec hard-drive.
β οΈ Warning: Do not turn off the cable while copying large amounts of data, this can damage the file system or corrupt the audio file, after which it will stop playing.
Setting up the quality and parameters of the recording
The quality of the recording depends on the settings set in the Dictaphone application. By default, the system can choose the balance between the quality and the size of the file, but for important negotiations, these parameters can be changed manually, this is especially true if the recording is used as proof.
Go to the voice recorder settings (usually three dots or a gear in the corner). Find the "Record quality" or "Call settings" section. Here you can choose the bitrate. High quality will provide better legibility of quiet voices, but take up more space. For normal conversations, medium enough.
Also important is the audio source setting. Some Xiaomi models have the option of choosing a microphone: the main (lower) or additional (top/noise suppressing). For recording conversations, the best mode is that captures sound from the speaker and microphone at the same time, but this depends on the specific model of the processor and modem.

Use headphones with a microphone to record critical conversations, which will allow you to record the voice of the interlocutor directly from the line, eliminating background noises and echoes in the room.
Problems with reproduction and restoration
Sometimes users are faced with a situation where a file is in a folder, but it does not open or play as "broken" This can occur due to incorrect completion of a call, a system failure during recording or damage to the file system..m4a format may not be supported by older players on a PC without installed codecs.
If a file is not readable on your phone, try opening it through a third-party player, such as VLC for Android or MX Player. These applications have their own codecs and are often able to reproduce what a standard player does not see. If the file is physically damaged, there are special reenactors for audio, but they do not give a 100% guarantee.
In the case of accidental file deletion, the chances of recovery depend on how long it has been since the deletion. If you immediately stopped using your phone and did not record new data, you can try data recovery software such as DiskDigger, although deep scanning often requires Root rights.

Timely backup of the folder call_rec On a cloud drive or PC, the only reliable way to ensure that important conversations are safe for the long term.
