Xiaomi’s modern smartphones have become powerful multimedia centers that allow users to consume content, but also actively create it. One of the most popular features for bloggers, gamers and educators is the ability to capture images from the display. However, standard recording of video without audio often loses its meaning, making the video uninformative for the viewer, which is why the question of how to record a screen with sound on Xiaomi remains one of the most popular in the user community.
The built-in MIUI shell tools and the new HyperOS provide advanced capabilities to customize the capture process. You don’t need to look for third-party applications that can overload RAM or contain advertising. The system recorder can work with internal audio stream, which allows you to save clean sound of the game or video without extraneous noise from the environment.
In this guide, we will take a closer look at all the nuances of audio track setup, look at the differences between microphone recording and system sound, and identify hidden features that not all Redmi and Poco owners know about.
Basic setting of the built-in screen recorder
Before you start debugging the parameters in detail, you need to activate the recording module itself. In most current models, such as the Xiaomi 13 or Redmi Note 12, this component is already integrated into the control system. To call the quick access panel, you just need to unlock the device and swipe your finger from the upper right corner of the screen down. If the Screen Record icon is missing in the first row, click on a pencil or three dots to edit the widget list and drag the desired element to the active panel.
When you start the app, you'll have a preview interface where the key audio settings are, and it's not just about pressing the start button, it's about preconfiguring the signal source. By default, the system can only offer a microphone recording, which requires you to be completely silent in the room. Switching to the internal sound changes the quality of the result dramatically, eliminating echoes and street noise.
⚠️ Warning: When you try to record protected content (Netflix movies, paid courses, some banking apps), the screen can turn black and the sound can go abyss. DRM, and bypass it by regular means is impossible.
The interface of the settings may vary slightly depending on the firmware version, but the logic remains the same: at the top of the window are the audio source select buttons, and below are the video quality and touch display parameters, a competent combination of these settings will allow you to create a professional video in seconds.
Sound Sources: Microphone vs System Audio
The main dilemma that the user faces is the choice between recording the sounds of the device and recording from the microphone. In the recorder menu, this is usually presented as a switch or drop-down list. Understanding the difference between these modes is critical to achieving the desired result. System sound captures the digital audio stream directly from the processor, providing crystal clear playback of music, the effects of shots in games or the voice of the interlocutor in the messenger.
The microphone mode, in turn, records everything your phone speaker hears, including fan noise, room conversations and street hum. This option is suitable exclusively for video comments when you need to superimpose your voice over what is happening on the screen, but it is worth remembering that in this case, the quality will depend on the acoustics of the room.
There is also a combined mode available on some versions of MIUI 14 and HyperOS, which allows you to simultaneously write the system track and your voice through the microphone. This is ideal for creating tutorials where you need to show actions on the screen and comment on them in real time. Activating this feature requires attention, since the volume of your voice must be above the background noise for the comment to be heard.
💡
If you're recording gameplay, always choose System Sounds, which will take away the keyboard sound and the fingers rubbing against the screen, leaving only the clean audio of the game.
Step-by-step instruction for activating recording with sound
To ensure you get audio video, follow a clear action algorithm. An incorrect sequence of steps can cause you to record a long video that turns mute. First, make sure the phone doesn't turn on Do Not Disturb mode, as it can block some system sounds or notifications you plan to capture.
Next, follow the following steps to set up before starting:
- 📱 Open the notification curtain and find the Screen Record icon».
- 🔊 In the window that opens, find the microphone icon or the item "Sound Source».
- 🎙️ Select System Sounds for Clean Audio or Microphone for Voice.
- ⚙️ Check the volume slider in the media settings to make sure the sound is not twisted to zero.
After selecting the settings, press the red recording button. You will have a few seconds before the actual capture starts to roll the menu and take the desired position in the application. During the recording process, a floating control panel can be displayed on the screen, through which you can pause the process at any time or switch the sound source on the fly, although the latter feature is not available on all models.
☑️ Pre-recording checks
Extended quality and bitrade parameters
The quality of the audio track is directly dependent on the selected video parameters. In the recorder settings (available through the gear in the recording menu), you can find the section responsible for resolution and frame rate. High resolution, such as 1080p or 2K, often correlates with a higher bitrate of the audio stream. If you choose the minimum settings to save space, the sound can become deaf and indistinct.
Special attention should be paid to frame rate. For dynamic games, it is recommended to set a value of 60 fps, which will make the picture smooth and the sound synchronized with the action. When writing static instructions or presentations, 30 fps is enough, which will significantly reduce the load on the processor and reduce the size of the final file. Remember that 4K recording is not available on all devices and can cause overheating of the case.
| Parameter | Recommended value | Impact on sound |
|---|---|---|
| Permission | 1080p (Full HD) | Standard quality of audio coding |
| Bitreit | 12-20 Mbps | High bitrate improves the clarity of the soundtrack |
| Codec | H.264 / AAC | AAC provides better compatibility and quality |
| Frequency of personnel | 60 FPS | Improves sound synchronization in dynamic scenes |
Experiment with settings on short stints to find a balance between quality and file size. Recording at maximum quality will quickly fill up internal memory, especially if you plan to create long video tutorials.
Hidden bit-trade setup
Recording sound from specific apps and games
Not all apps are equally sensitive to audio capture: Messengers like Telegram or WhatsApp, as well as social networks, can block the recording of internal audio for privacy reasons, in which cases the system will automatically switch to the microphone or issue a warning, games, especially heavy projects like PUBG Mobile or Genshin Impact, are usually perfectly recorded through the system channel.
If you notice that a particular app doesn't write sound, check its individual permission settings. From the Settings menu → Apps → Screen Recorder (or Screen Recorder), make sure you allow microphone use if you plan to comment on the process.
There is a nuance with voice calls. Recording conversations through standard means (GSM/VoLTE) is often impossible due to legal restrictions and technical blockages at the modem level. However, video calls over the Internet (Viber, Zoom, Skype) can be recorded with sound if the source is selected "Microphone", because the sound is output through the speaker and immediately captured.
⚠️ Note: Recording telephone conversations without warning may violate your country's laws. Use the recording function solely for personal or educational purposes with the consent of participants.
Solving problems with lack of audio
When you're recording video but you're not sounding, it's quite common. The first reason is always a volume conflict. Make sure you don't turn the media volume down to zero during the recording. The system recorder captures the level of the signal that's set at the time of capture. If the speaker is silent, the file will be silent.
The second common problem is that third-party equalizers or audio amplification apps can intercept the audio stream without allowing the recorder to access it. Try temporarily disabling Dolby Atmos or other sound effects in the phone settings. It's also worth checking if Bluetooth headphones are connected that can intercept the audio output while the recorder waits for the signal from the speakers.
If nothing works, try clearing the Screen Record cache. Go to Settings → Apps → All Apps → Screen Record → Memory → Clean. This will return the recorder settings to factory values and fix software glitches.
💡
90% of sound problems are solved by checking the media volume slider before recording and choosing the right source in the recorder menu.
Where records are stored and how to edit them
When the process is complete, the file is automatically saved to the gallery. Usually, a separate Screen Recorder or Screen Recorder album is created to avoid mixing screencasts with normal photos. /MIUI/screen_recorder/ or /DCIM/ScreenRecorder/. Default file format — MP4, It provides maximum compatibility with any video player and social networks.
The built-in editor, available immediately after recording stops, allows you to do basic cropping of the beginning and end of the video, but for more complex processing, such as subtitling or mixing audio paths, it is better to use specialized applications like CapCut or InShot. They easily import files created by the Xiaomi system recorder.
Remember to periodically check the folder with records and delete unsuccessful duplicates. High-resolution videos take up a significant amount of memory, and a crowded drive can cause a new record to interrupt in half-word or not to start at all.
