How to set up a microphone on Xiaomi Redmi Note 10 Pro: the full guide

Xiaomi Redmi Note 10 Pro is equipped with high-quality microphones that are responsible for recording voice during calls, videos, voice messages and work with voice assistants, but even in such a device can cause problems: low volume, background noise, distortion or complete absence of sound, most often due not to hardware malfunctions, but to the wrong settings of the program or system.

In this article, we will explore how to check the microphone, adjust its parameters manually, fix typical problems and optimize sound recording for different scenarios, from calls to streams. Particular attention will be paid to the hidden features of MIUI, which allow you to finely adjust sensitivity and suppress noise without third-party applications.

If you find that the interlocutor does not hear you during a conversation or voice commands are not recognized, do not rush to carry the phone to the service. In 90% of cases, the problem can be solved independently in 5-10 minutes, following our recommendations.

How to check the performance of the microphone on the Redmi Note 10 Pro

Before you set up the microphone, make sure it works at all. The Redmi Note 10 Pro has three microphones: the main one (below the USB-C connector), the noise suppressor (at the top of the case), and the video recording option, which can be checked in several ways.

The easiest way is to use a built-in voice recorder. Open the Dictaphone app (if not available, download it from Google Play), click on the record button and say a few words. Play it back: if the voice is heard clearly, without wheezing or fading, the microphone is good. If the sound is missing or badly distorted, the problem may be in the settings or the hardware.

• 📱 Call over the bell: Call another phone and ask the person to rate the quality of your voice. If they hear you quietly or with interference, the problem is with the microphone for calls (main or noise-cancelling).
• 🎤 Verification through voice assistant: Activate Google Assistant or Alice with voice. If commands are not recognized, the top microphone may not work.
• 🎥 Video recording: Take a short video in the Camera app and check the audio track. If there is sound but with noise, you will need to adjust the sensitivity.

If the microphone doesn't work in any of the tests, it could be mechanical damage (like after a phone falls) or contamination of the holes, in which case you should contact the service center, and if there is sound, but the quality leaves much to be desired, move to the next section.

Basic settings of the microphone in MIUI

The MIUI operating system on the Redmi Note 10 Pro offers some built-in microphone management tools, and most users are unaware of their existence, because they're hidden in the back of the menu, so let's figure out where to look for them and how to set them up.

The first thing you should do is check the sensitivity level of the microphone.

1. Go to Settings → Sound and vibration → Sound quality.
2. Select the Microphone Settings option (in some versions of MIUI it may be called Voice Improvement).
3. Activate the microphone boost slider and adjust it to the average (usually 50–70%).

If this item is missing, your firmware version does not support manual configuration, in which case you can use third-party applications, which we will discuss later.

Another important option is noise cancellation, which automatically suppresses background sounds (wind, transport, other people's voices) during calls, to turn it on:

1. Open Settings → Special features → Improve the sound.
2. Activate the Noise Reduction Switch when making calls.

Note: This feature can lower the overall volume of your voice, so test the microphone again after it is turned on.

💡

If after activating noise cancellation, the interlocutor began to hear you worse, try to turn off this feature and instead use headphones with a microphone (for example, Xiaomi Earbuds) for important calls.

Customizing the microphone for calls and voice messages

Most of the time, microphone problems are when you're calling, and if someone complains that they can't hear you well or that your voice sounds like a barrel, try the following steps:

1. Check the microphone mesh. The microphone holes on the Redmi Note 10 Pro are located in the lower and upper parts of the case. They are often clogged with dust or villi from your pocket. Carefully clean them with a soft brush or compressed air (do not use needles or toothpicks!).
2. Turn off Bluetooth devices. If you have wireless headphones or speakers on your phone, the microphone can transmit sound to them. Before you call, turn off all Bluetooth gadgets.
3. Reset network settings. Sometimes the sound problems during calls are due to incorrect mobile network settings. Go to Settings → Mobile Network → Reset network settings and confirm the action.

If the quality hasn't improved after this manipulation, try using the hands-free mode. When you call, click the speaker icon, this will use the top microphone, which can work better than the main one. Also check if the In-plane mode is activated or Do Not Disturb, as they can block the microphone.

For voice messages in messengers (WhatsApp, Telegram, Viber), the microphone is set up directly in the applications.

1. Open the chat and hold the microphone icon to record the message.
2. Before recording, click on the three dots in the upper right corner and select Record Settings.
3. Activate the Voice Improvement option (if available).

Optimizing the microphone for recording videos and streams

When recording videos or streaming on TikTok, YouTube or Twitch, sound quality is as important as picture quality. Unfortunately, the standard camera settings on the Redmi Note 10 Pro don't always deliver perfect sound. Here's how to improve recording:

In the Camera app, go to Settings → Video Settings and find the Microphone. Here you can select one of three modes:

• 🎤 Stereo: uses both microphones to create surround sound (suitable for music recordings).
• 🔇 Monosound: Records sound from one microphone (less noise but less saturated sound).
• 🎧 External microphone: automatically switches to a connected headset or lavalier microphone.

For streams, it's better to use an external microphone, but if you don't have one, select Monosound and manually reduce the sensitivity. You should also turn off the option to Improve Sound in the camera settings - it often adds distortion.

If you're streaming games, install Streamlabs or OBS Camera from Google Play, which allows you to set up your microphone separately and suppress noise in real time, for example, in Streamlabs:

1. Launch the application and go to Settings → Audio.
2. Select the Microphone (Xiaomi Redmi Note 10 Pro) as the source.
3. Activate Noise Reduction and Compressor filters.
4. Adjust the volume level so that the indicator is in the yellow zone (does not go into the red).

Important: When recording 4K video, the microphone can automatically lower the bitrate of sound so as not to overload the processor. If the sound gets worse in high resolution, try recording in Full HD (1080p).

Solving Common Problems with the Microphone

Even after you set up the microphone correctly, the Redmi Note 10 Pro can malfunction.

If the microphone stopped working after the firmware update, try to roll back to the previous version of MIUI.

1. Download the stable firmware version for Redmi Note 10 Pro from the official Xiaomi website.
2. Go to Settings → About the phone → System update.
3. Click on the three dots in the upper right corner and select Select the firmware file.
4. Specify the downloaded file and confirm the installation.

Before rolling back, make a backup of the data, as the process will reset all settings.

Third-party applications to improve microphone sound

If the built-in MIUI tools don't work, you can use third-party apps that offer advanced noise reduction, equalizers, and even the ability to record sound from different sources separately.

Here's the top.-3 Apps for setting up the microphone on Redmi Note 10 Pro:

• 🎛️ Wavelet: a free equalizer app for the microphone, which allows you to increase low voice frequencies and reduce noise.
• 🔊 Microphone Amplifier: amplifies microphone signal in real time. Useful for streaming and video calls. Download to Google Play.
• 🎙️ Voice Changer: In addition to changing voice, it has a built-in noise maker and compressor. Suitable for recording podcasts. Download to Google Play.

Before installing third-party apps, check their permissions. Some programs request access to contacts or locations, which is not always justified. Also remember that only one application that controls the microphone can work at a time, otherwise conflicts will arise.

For professional audio recording (for example, for podcasts or music tracks), it is better to use an external USB microphone connected via a USB-C adapter → USB-A. Redmi Note 10 Pro supports OTG, so there will be no compatibility problems.

💡

Third-party microphone apps can significantly improve sound quality, but they consume additional battery and processor resources. Use them only when needed, and there are built-in MIUI tools for everyday calls.

How to protect the microphone from damage and pollution

The microphones on the Redmi Note 10 Pro are quite reliable, but they are easy to damage if handled carelessly. Here are some tips to help extend their lifespan:

⚠️ Warning: Never blow into microphone holes with your mouth - this can damage the membrane. Use only a soft brush or a special can of compressed air to clean.

• 🛡️ Use a microphone-protected case. Some cases have cutouts that cover microphone holes from dust, but do not block sound.
• 🚿 Avoid moisture, even if your phone is protected. IP53, Microphones can fail when they come into direct contact with water.
• 🔇 Don't put the phone down with the microphone, which increases the risk of dust and scratches on the mesh.
• 🎧 Turn off the microphone when you don't need it. In some apps settings (such as Zoom), you can turn off the microphone by default to reduce the load on it.

If you often record sound in noisy places (outdoors, in traffic), consider buying a windshield for the microphone. This is a small device that attaches to the microphone grid and reduces wind noise. The Redmi Note 10 Pro will suit a universal windshield with a diameter of 5-6 mm.

Also update your phone’s firmware regularly. Xiaomi often releases patches that improve microphone performance and fix sound bugs. To check for updates, go to Settings → About Phone → System Update.
