Xiaomi and Redmi smartphones, which run on MIUI and HyperOS shells, have a powerful built-in voice recorder that allows you to record phone conversations, a feature that is often indispensable for saving an important agreement, confirming an order, or simply for a personal archive. However, after the call is completed, many users face difficulties: where exactly the file is saved and how to quickly find it among the system folders.
The Android system logic that the devices are built on provides multiple layers of media access. The conversation can be recorded in both the standard gallery and hidden directories of the file system, which can not always be accessed through a regular conductor. Understanding the folder structure will help you avoid wasting time on chaotic searches and instantly access the desired audio file.
In this article, we will take a look at all the possible search paths, auto-save settings, and ways to transfer data to your computer, learn how paths differ on different versions of Android and how to properly manage your voice library.
Search through the standard Dictophone application
The fastest and most obvious way to find a recording you just made is to go to a native app that automatically starts when you turn on the recording function during a call. On Xiaomi smartphones, it's called a Recorder and has a characteristic icon with a microphone. When you open the application, you immediately see a list of all available records, sorted by date of creation.
The application interface allows you not only to listen to the file, but also to perform basic manipulations: rename, delete or send a contact via the messenger. Audio recording in the list is usually indicated by the call time and phone number (if it is determined), which greatly simplifies navigation through the archive. If you do not see the desired file, check tabs or sections within the application, as they are sometimes divided into "All records" and "Favorites".

If the recorder list is empty, check if the recording function was turned on directly during the call - the record indicator should have been lit in red on the call screen.
To better manage files within the app, you can tap three dots in the corner of the screen or hold your finger on a specific file. A context menu will open where the file's properties, including the exact size and duration, are available, and this is especially useful if you want to free up space in the device's memory by deleting old or unnecessary audio files.

The Dictophone app is the main storage where records are automatically structured by date, eliminating the need to search them manually in folders.
The path to files through the Explorer on the smartphone
If you need to copy a file, send it by email, or just look at its location in the file system, you have to use the built-in Explorer. The logic of storing files has changed with the release of new versions of Android, so there can be several ways. Most often, files are located in the MIUI root folder, which is created by the system on the first run.
Standard route for finding conversation records on current versions MIUI It looks like this: you need to go to the internal storage, find the folder. MIUI, later sound_recorder and finally, call_rec. It's in this directory. call_rec All your phone calls are stored. Files usually have an extension.m4a or.mp3 and named according to the date and time of the call.
βοΈ File path check
It is worth noting that in some cases, especially on older versions of firmware or with changed settings, the path may be different -> sound_recorder. If there are no files in one folder, it makes sense to check adjacent directories, and Explorer has an Audio category that aggregates all audio files from across the device, which can make it easier to search if you don't remember the exact path.
β οΈ Note: Do not delete or rename system folders MIUI or sound_recorder. This can cause a dictaphone to malfunction and new records will cease to be saved or will be lost.
Where the records are stored on the computer (when connected via USB)
When connecting a smartphone to a computer through USB-cable and choice of file transfer mode (MTP), The folder structure remains similar to what you see in mobile Explorer, but navigation on a large screen is often more convenient, especially if you want to find a specific file among hundreds of others.
You will need to open the internal memory of the phone (Internal Storage) and follow the already familiar path: MIUI β sound_recorder β call_rec. Here you can copy recordings of conversations to your computer's hard drive, back up or edit them in professional audio editors. Direct access to the file system allows you to quickly sort the archive by size or date of change.
| Parameter | Path/file description | Note |
|---|---|---|
| The main path | /MIUI/sound_recorder/call_rec | Standard for MIUI 12, 13, 14, HyperOS |
| An alternative path | /Music/sound_recorder | It is found on older versions of Android |
| File format | .m4a or.mp3 | Depends on the recording quality settings |
| File name | Date Time Number | Automatic generation by the system |
If you connect to a computer folder MIUI not displayed or access restricted, try using another USB-Sometimes Android security may ask permission to access files on your smartphone screen β be sure to confirm this request, otherwise the computer will not see the contents of the folders.
Automatic recording and sound quality setting
To avoid looking for a record button every time an important call, Xiaomi has an automatic recording feature, which can be activated by opening the Dictaphone app, clicking three dots in the corner and selecting Settings, where you need to find the "Record Calls" item and enable automatic recording for all numbers or only for selected contacts.
You can adjust the sound quality in the same settings menu, and you can have low, standard and high options, and high quality, which allows you to have better speech intelligibility, but takes up more space in the memory of the device, and if you're often in long conversations, it makes sense to choose standard quality to save gigabytes.
You can also set the settings to tell you whether you need to sound a recording alert for the person you're talking to, and many countries require that you notify the other person, and if you have this feature on, when you start recording, you hear a voice message that the conversation is being recorded.

Problems with access and lack of files
Users may find themselves in a situation where the recording appears to have been made but the file is nowhere to be found, often due to Android security restrictions. 11 And above, that hide the folder. Android/data Xiaomi's built-in Explorer usually has the necessary rights, but third-party file managers may not see the contents of the folder. call_rec.
Another reason is overflowing memory, because if there's no room left on the phone, the system can't physically save the new audio file, even if the recording is visual, in which case the system memory blocks the creation of new data, and it's worth checking if the phone has "Do Not Disturb" mode or special profiles that may conflict with the operation of the recorder.
β οΈ Warning: Clearing the cache of the Phone or Recorder app does not delete the recordings themselves, but it can reset the automatic recording settings.
If files are missing after a firmware update, check if the path to them has changed. Sometimes with major MIUI updates, the folder structure changes, and old records may end up in the archive folder or require re-indexing of the media library.
Transfer and backup of records
Regularly backing up important conversations is good practice, as accidental resets or phone breakdowns can cause data loss. call_rec on a computer or in cloud storage (Google Drive, Yandex.Disk, Mi Cloud).
When using cloud services, you can set up automatic synchronization of the record folder, which ensures that even if you lose your device, the entire negotiation history will be available from any other gadget. Note that synchronizing large volumes of audio requires a stable connection to the Wi-Fi network to avoid spending mobile traffic.

Backup of the folder call_rec on external media is the only guaranteed way to save records when flashing or resetting a smartphone to factory settings.
To transfer to another phone Xiaomi enough to copy the folder sound_recorder After transferring to a new device and placing files in a similar directory, they should automatically appear in the Dictaphone application due to indexing of the system's media files.
