Poco X3 Pro smartphone owners often face the need to save an important conversation, whether it is a business conversation or confirmation of agreements with service services. However, once completed, the user may not find the saved file in the usual places, since the MIUI and HyperOS file system have its own specific logic of organizing data. Understanding the structure of directories allows you to quickly find the desired audio recordings, transfer them to the computer or clean the internal memory of the device from unnecessary debris.
Modern versions of Xiaomi’s shell use different audio encoding formats, which also affects which folder the final file will be in. Depending on the recording quality settings and the Android version, the path may vary slightly, but the basic directory remains unchanged for most models of the brand. In this article, we will discuss in detail all possible paths, search methods through file managers and the nuances of working with cloud services to save your audio archive.
Standard path in device memory
By default, all records created by the built-in voice recorder or phone call recording feature are stored in the smartphone's internal storage.The root directory is usually named MIUI, inside sound_recorder. This is where all audio data is stored unless the user has changed the default save settings to an external memory card.
To access files, you need to open any file manager, like standard Explorer or the more advanced Total Commander. At the root of the internal memory, you'll see many folders with application and system service names. MIUI, Go to it and select a subsection sound_recorder. Inside this directory are often several folders that sort records by source type.
💡
If you don’t see the MIUI folder at the root, check if the hidden files are included in the Explorer settings, although this directory rarely requires this.
It is important to note that inside the folder sound_recorder For example, voice recorders are often separated from call records, which can be marked with a date or time prefix. X3 Pro uses a logical structure that allows you to sort thousands of files without losing system performance.
Searching for telephone records
The mechanism of saving telephone conversations deserves special attention, since they often take priority for users. Unlike a recorder that writes sound through a microphone, the call is recorded directly from the audio stream, and the system assigns special metadata to such files. You can find them by going through the internal memory path. → MIUI → sound_recorder → call_rec.
If the folder call_rec When it is empty or absent, it may mean that the automatic recording is disabled or conversations are saved to the cloud.In some regions, due to legal restrictions, the call recording function may be hidden or require activation through a change of region in settings.m4a.aac, which provides good quality with a small size.
Why the folder call_rec may be empty?
To make it easier to navigate through the call archive, you can use the built-in Explorer sorting system, which allows you to sort files by date of change, size or name. If you're looking for a specific conversation, the easiest way to sort the list by date descending is because the latest records will be at the top of the list, and this is especially true for the Poco X3 Pro, which supports working with large amounts of data without delay.
Using cloud services for storage
Xiaomi’s ecosystem offers integration with Mi Cloud, which allows you to synchronize voice recorders between devices. If this feature is activated, copies of your audio files can be stored not only in the phone’s memory, but also on the company’s servers. This is a great way to protect data from loss in the event of a smartphone breakage or reset to factory settings.
To check sync status, go to Settings → Mi → Mi Cloud → Recorder. Here you can see if sync is enabled and how much space your records take up. Cloud storage is especially useful for users who often change devices or use multiple Xiaomi gadgets at once.
Keep in mind that free cloud space is limited and syncing of new files will stop when overflowing, in which case old records can be deleted from the device if appropriate storage optimization is enabled, and check your account status regularly so that you do not lose important conversations that may be needed in the future.
Working with files through a computer
For mass copying or editing records, it is most convenient to connect Poco X3 Pro to the computer through USB-Cable. After you connect, select the mode of operation. USB «File transfer» (MTP) It's going to be in the notification curtain of your smartphone, and on your computer, it's going to be like an external drive, and you can navigate it in the same folder structure that I mentioned earlier.
Using a PC allows you to quickly rename files, give them clear names instead of automatic digital codes, it is also easier to sort and archive on a large screen. For transferring large amounts of data, it is recommended to use the original cable that comes with the kit to ensure maximum data transfer speed through the USB Type-C port.
☑️ Preparation for file transfer
If your computer can’t see your phone, try replacing the cable or USB-Sometimes you need to install drivers, although modern versions of Windows 10/11 When you're done with files, make sure you safely extract the device to avoid damaging the file system.
Table of paths to different types of audio
To systematize the information, the following table shows the exact paths to the different types of audio recordings on Xiaomi Poco X3 Pro. Keeping this structure in memory will help you navigate the file system faster.
| Type of record | The path in the file system | File extension |
|---|---|---|
| Call recording (automatic) | /internal_storage/MIUI/sound_recorder/call_rec | .m4a /.aac |
| Recording of the recorder | /internal_storage/MIUI/sound_recorder/rec_YYYYMMDD | .m4a |
| Screen recording (with sound) | /internal_storage/DCIM/screen_recorder | .mp4 |
| WhatsApp voice messages | /internal_storage/Android/media/com.whatsapp/WhatsApp/Media/WhatsApp Voice Notes | .opus |
Please note that the paths starting with /internal_storage, If you've used a microSD card, the folder structure will be similar, but it will be at the root of the external drive. Some applications can create their own directories to store audio, ignoring standard paths. MIUI.
Customization of quality and format of recording
The quality of the files you save depends on the settings of the recorder. In the Dictophone application, you can choose the recording mode: Standard, High quality or Compressed. The choice of mode affects the bitrate and, accordingly, the size of the final file. For important negotiations, it is recommended to choose high quality, so as not to lose the details of the conversation.
You can also find the settings menu with the Noise Removal option, which uses AI algorithms to clean the audio stream from background sounds. On the Poco X3 Pro, this feature works quite efficiently thanks to a powerful processor. However, it is worth remembering that aggressive noise cancellation can distort the voices of interlocutors, making them metallic.
💡
The optimal balance between sound quality and file size is achieved in Standard mode, which is suitable for 90% of household tasks.
If you plan to use records for transcription or professional analysis, choose the highest quality available. Larger files take up more space but provide a cleaner signal for software processing. Don’t forget to clean the folder periodically. sound_recorder, Not to overflow the system partition.
Solving problems with missing files
Sometimes users are faced with a situation where the record seems to be being recorded, the indicator was on fire, but the file is not in the folder. First of all, check if the device memory is full. If there is critically little space, the system can interrupt the saving process. Also, make sure that the Phone and Recorder application are given all the necessary permissions in the privacy settings menu.
⚠️ Note: If you use third-party apps to record calls, they may save files to their own folders, such as, /CallRecorder or /Recordings at the root of the memory. Check the settings of the specific application.
In rare cases, it may be necessary to clean the cache of the voice recorder application. This is done through the Settings menu → Apps → Recorder → Storage → Clear the cache. This operation will not delete your records, but can correct errors in the program. If the problem persists, try restarting the smartphone to reset temporary system errors.
