The built-in voice recorder in Xiaomi smartphones is a powerful tool that users often underestimate. It can replace professional devices for recording lectures, interviews or personal notes thanks to high bitrate support and advanced noise reduction algorithms. The standard application “Dictophone” in the shell of MIUI (or HyperOS) offers functionality that goes far beyond simple recording of sound.
Understanding the intricacies of this app will allow you to create studio-quality audio recordings right in your pocket, not only can you save your voice, but also automatically translate it into text, which greatly speeds up the work with notes. In this article, we will discuss all aspects of using a regular recorder from Xiaomi.
The interface may seem minimal, but it hides a lot of hidden possibilities. Getting the settings right before you start a session will help you avoid future audio quality issues. Let's look at how to unlock the full potential of your device.
Interface and basic recording management
When you first start the app, you'll see a clean screen with a large start button, which is usually located at the bottom of the display and has a characteristic red color, and you click on it instantly starts capturing audio, and the timer counts the session time, and at the top of the screen you'll see the current duration and level of the incoming signal.
It's important to note that while recording, you can turn off the screen, and the system will continue to work in the background, saving battery life, which is especially convenient for long interviews or lectures, when you don't have to keep your smartphone on all the time, but if you use high-quality mode, the energy consumption can be higher.
- 🔴 Start/Stop button – the main element of process control.
- 🏷️ Marker – allows you to put labels on the timeline in real time.
- 📂 File List – Access to the archive of all stored audio recordings.
- ⚙️ Settings – menu to change microphone parameters and format.
At the top of the screen, there are often additional tools, such as a mode switch or a recording search. The interface adapts to the orientation of the screen, but in landscape mode, the functionality can be limited. For most tasks, portrait orientation is quite enough.
⚠️ Note: If you receive an incoming call during the recording, the recording may be interrupted or continued depending on the version. MIUI. It is better to turn on the “Do Not Disturb” mode before an important session.
Customization of audio quality and formats
For best results, you need to adjust your recording settings correctly. By default, your smartphone can use a compressed format to save space, which reduces the detail of the sound. To change this, go to the app settings menu through three dots or a sidebar.
Here you will find the item "Record quality." For musical instruments or pure voice, it is recommended to choose a lossless or maximum bitrate. If you need to record a long lecture and save space, standard quality will do. The difference in file size can be tenfold.
The file format also matters. Current versions of the shell support MP3 and AAC, which are compatible with any player. Some models allow you to choose the sampling frequency. 44.1 kHz is enough for speech, but for professional processing, you better choose 48 kHz.
💡
Use MP3 format with a bit rate of 320 kbps for the optimal balance between the quality and file size when transferring via messengers.
Don't forget to check the source of the sound. In the settings, you can choose to use the main microphone, an additional (if any) or a headset. Connecting an external loop through a 3.5 mm connector or USB-C will automatically switch the input to the external device.
Recording and noise cancellation modes
One of Xiaomi's strengths is that it has presets for different scenarios, and at the bottom of the screen or in the mode selection menu, there are options like General, Interview, Lecture and HD. Each mode adjusts the microphone sensibility and processing algorithms differently.
Interview Mode optimizes recording for situations where people are on opposite sides of a smartphone, by increasing the capture of sound from the front and back, ignoring side noises, while Lecture Mode focuses on the remote source of sound, ignoring the whispers in the audience.
| Regime. | Appointment | Noise processing |
|---|---|---|
| Common | Universal record | Standard. |
| Interview | Voice reinforcement | |
| Lecture. | Audience, auditorium | Echo suppression |
| HD | Music, nature | Minimum |
Noise reduction works at the software level, it effectively removes air conditioning hums or street noise, but it can slightly distort the timbre of the voice when you're at maximum tune-up. Experiment with sensitivity levels in a quiet room to find balance.
💡
The right recording mode is more important than the smartphone model. The lecture mode works wonders in large rooms.
Text work and speech recognition
Xiaomi's current smartphones can translate voice into text right while recording, a feature called "Speech Recognition" or "Transcribation," which is particularly useful for journalists and students, and to activate it, you need to tap the corresponding microphone icon with letters before recording.
The system supports several languages, including Russian and English, and the accuracy of recognition depends on the speaker's diction and the absence of strong extraneous noises, and after the session is over, you will receive a text file synchronized with the audio.
Text can be edited, copied or exported to other applications, eliminating the need to print large amounts of information manually, but for complex technical terms, manual editing may be required.
- 📝 Automatically create a text file when you stop recording.
- 🌐 Support for language switching on the fly (in new versions).
- ✏️ Ability to edit text within the application.
It is worth considering that this feature requires an active Internet connection to work, since processing often takes place on servers. Without a network, the function may not be available or work with a limited vocabulary.
Hidden recording and control with lock
In some situations, you need to record a discreetly conversation. Xiaomi recorder allows you to record even with the screen off. Moreover, there is a recording function when the phone is locked, although its availability depends on the specific version of the firmware and region.
To start recording from a locked screen, you can set up a quick start, often via a combination of buttons or a voice command, and you can also turn off the start and end sounds in the settings to avoid attracting attention.
Settings → System applications → Dictator → Recording with the screen off⚠️ Attention: Keep in mind the laws of your country, that recording a conversation without warning the person may be illegal.
If the screen still lights up when recording begins, you can use the “Block Screen” function inside the app, if it is available in your version of MIUI. This will darken the display, making the process invisible to others.
☑️ Checking settings before an important entry
Editing and managing files
Once the recording is complete, the file is stored in the archive, the built-in player allows you to listen to the result, speed up playback or cut out unnecessary fragments, and the trim function works fairly accurately, allowing you to delete the introduction and conclusion.
Files can be renamed, which is critical to archive organization, the system automatically assigns names by date, but it is better to give descriptive names, and the feature of adding to favorites is also available for quick access to important notes.
File export is done through the standard Share menu, you can send the audio file to messengers, cloud storage, or your computer, and you can transfer it over Bluetooth and Wi-Fi Direct.
Where are the records of the recording physically stored?
For ease of navigation, records are sorted by date, you can use keyword search if you have transcription enabled, and that allows you to instantly find the desired phrase in hours of audio.
