How to connect the microphone to the smartphone Xiaomi

Modern smartphones in the Xiaomi, Redmi and POCO line have impressive multimedia capabilities, but regular microphones often do not cope with the tasks of professional recording. Device owners strive to improve the sound quality for video blogging, podcasts or business negotiations. Connecting external acoustics allows you to achieve studio clarity and remove background noise, which inevitably captures the built-in module.

Peripheral integration depends on the interface type and version of the MIUI or HyperOS operating system. Some methods require minimal action, others involve adapters or special applications. It is important to understand that not all models support audio output through a digital port without additional drivers. In this article, we will discuss all the current ways of connecting equipment.

Choosing a compatible microphone for Xiaomi

The first step is to determine the type of connector on your gadget. flagship Xiaomi models are most often deprived of the classic 3.5 mm audio jack, relying on the USB Type-C port. Budget devices of the Redmi Note series can save "minijack", which makes it easier to choose accessories. Ignoring this nuance will lead to the purchase of incompatible equipment.

There are three main categories of input devices on the market: loop models are popular with bloggers because of their compactness; studio capacitor microphones require power, and dynamic options are reliable. OTG, This technology allows the smartphone to transmit energy and data through the USB-port.

Also worth considering is the length of the cable and the presence of windscreen if you plan to shoot outdoors. Cheap Chinese counterparts may not have a built-in DAC (digital-to-analog converter), which makes the smartphone simply not see them.

Connection via 3.5 mm connector

If your smartphone is equipped with standard audio output, the procedure is as simple as possible: you will need a microphone with the appropriate plug or adapter. insert the device into the connector before the characteristic click. Android system usually automatically switches the sound source from the internal to the external.

But there's an important technical nuance about the slinging: the CTIA standard used in most modern Xiaomi is different from the old OMTP. If you're using a very old headset or a cheap Chinese microphone without labeling, the sound may play with distortion or not work at all.

To test your performance, run a tape recorder and make a test record. Touch the microphone body -- if you hear a loud hum or crackle, you may need to ground or change the cable, sometimes helping to reconnect the device when the screen is off.

⚠️ Warning: Do not use force when inserting a plug.The 3.5mm connector in Xiaomi budget models may be less protected from mechanical damage than in flagships.

Use USB Type-C and OTG

Digital connectivity via the charging port is the preferred option for today's models, and it provides digital signal transmission bypassing the noisy analogue path of the smartphone. USB-adapter.

Make sure USB OTG is activated in the settings. Most MIUI firmware has it turned on by default, but some HyperOS builds require manual activation in the developer menu or in quick settings. Without this, the smartphone will not power an external device.

When connecting, pay attention to the notification in the curtain. The system must report the connection of a new one. USB-If you don't, try flipping the Type-C plug or using another adapter cable. Some powerful microphones may require external power that the phone can't provide.

It's worth noting that the Type-C port is also used for charging, and the only way to record sound and charge simultaneously is through a different route. USB-Power Delivery-enabled hub, otherwise you’ll have to monitor the battery level of the device.

Wireless Bluetooth connection

Wireless systems like Boya BY-WM8 or Saramonic Blink allow wireless audio transmission, pairing via a standard Bluetooth menu, and once connected, the smartphone perceives the system as a headset, directing all audio stream to an external receiver.

The main problem here is latency, and when recording video on the built-in camera, desynchronization can reach noticeable values, and professional camera applications have manual synchronization or automatic delay correction to solve this problem.

Connection stability depends on the Bluetooth version and whether there is interference on the air. Keep the receiver at a distance of no more than 5-10 meters from the transmitter. If the sound is interrupted, try turning off other wireless devices or restarting the communication module in the phone settings.

Configure the recording parameters in MIUI and HyperOS

Once you're physically connected, you need to programmatically configure your capture settings. Xiaomi's standard Dictophone app has limited functionality. For serious work, it's recommended to install third-party solutions like RecForge II or Easy Voice Recorder.

In the settings of the selected application, find the Audio Source section. Select the External Mic or USB Audio option. If you leave the "Default" value, the phone can continue to use the internal microphone, ignoring the connected hardware.

It's also important to adjust the bitrate and sampling rate. 44.1 kHz is enough for podcasts, 48 kHz is better for video to avoid being out of sync during editing. High values (96 kHz) may not be supported by some budget smartphone models.

💡

Use headphones with monitoring while recording to hear yourself in real time and control the volume level.

Comparison of popular connection interfaces

So for the sake of convenience, let's look at a comparative table of different connectivity methods, which will help you decide on your priorities: quality, convenience or price.

As you can see from the table, wired USB connectivity is the best balance between quality and stability, and wireless is good for reporting, where operator mobility is important.

💡

For professional video production on Xiaomi, always choose a wired USB or 3.5mm connection to avoid audio and video dissynchronization issues.

Solution and lack of sound

Often users are faced with a situation where the microphone is connected, but the recording is quiet or with noise. First of all, check the permissions of the applications. In the MIUI privacy settings, access to the microphone must be allowed for the program used (Camera, Recorder, Instagram).

If the sound is wheezing, maybe the input level is too high. Professional applications have a Gain slider. Turn it down. Also check if the microphone hole is covered with a cover or a finger.

⚠️ Note: When using cheap USB-The sound can disappear when the battery is below 20%, as the system does not have enough energy to power the DAC.

And in rare cases, it helps to reset the sound settings. ADB-And the easiest way to do that is to reboot a smartphone with a microphone already connected.

adb shell am broadcast -a android.intent.action.CLOSE_SYSTEM_DIALOGS

This command can help reboot the audio service without fully restarting the device, although the method's effectiveness varies from Android version to version.
